Time for a new home

2006-09-06T20:17:00.000-05:00

With much regret and yet excitement the Sargent Park Math Zone has moved to a new site. The reasons for leaving are that Blogger in Beta is a much better service. Please continue to use this site to see what happened over my first year of blogging.

Former students I encourage you to continue to use you classroom blogs as a way to communicate with each other and the math blogging community.

I enjoyed it and am looking forward to seeing what will happen this year. Below you will find links to the new Math Class blogs for Sargent Park School. To the seven wonderful people who have subscribe to this blog. Come on over to the new site and continue the journey. Comments are always welcome and appreciated.

New Homes for.....

Sargent Park Math Zone This will be the new class hub. Students will find out what they need to do for Blogging assignments and have the ability to be interactive in their learning.

816 The new class blog for this classroom. Its 33 students will become members and have opportunties online to reach new levels of learning.

817 The new class blog for this classroom. Its 31 students will become members and have opportunties online to reach new levels of learning.

841 The new class blog for this classroom. Its 32 students will become members and have opportunties online to reach new levels of learning.

873 The new class blog for this classroom. Its 31 students will become members and have opportunties online to reach new levels of learning.

Students will also post to their classroom wiki to create A Grade 8 Math Guidebook. This is a new and exciting opportunity to create a manual of everything that they have learned. The students will include problems and solutions, their scribeposts and growing posts.

The Scribe Post Hall of Fame will be a place to showcase the best class scribes.

The Growing Post Hall of Fame will house the best Growing Posts that the students create.

I hope you take time to visit our new blogs.

Mr. Harbeck
Thanks for watching our journey..... but it ongoing

A new year Dawns

2006-08-30T09:40:00.000-05:00

It comes time to say good bye to some very terrific blogs. These blogs will remain alive as former students come back and reminisce about the previous year. I hope that this years students use these blogs as examples to help them with this years work. Good luck to my former students who now are in grade 9 and welcome the new group of grade 8's who will be learning math in new exciting ways.

The new class blogs for 2006 are

8-16
8-17
8-41
8-73

I would like to thank the students for being such excellent learners and using technology to enhance their learning. I could not have done this without them.

Mr. Harbeck

Its August and its kewl-last post :(

These are all of the possible nets.
They are labelled, therefore already mentioning the are of the base.
Most important thing to remember about nets:
V= B x h OR l x w x h
Always use every combination possible

This is the question with parts A,B,C,D.
THe easiest way to find out the size of each part is to divide the entire square up into 16's.
Then all it is is a matter of counting the # of pieces in each section.

Rectangle Cylinder
V= l x w x h V= pi r2 x H
V= 90x35x45 V=3.14(50)(50)(120)
V=90x1575 V=3.14x2500x120
V=141750cm3 V=7850 x 120
V=942000 cm3
942000/141750
=6.64
=rounded to 7

Approximately 7 rectangular bales will fit into the cylinder.

The algebraic expression is 4x+4

1) Here are some layouts of boxes/rectangles with a volume of 8 units.

2) This is a box divided into four different parts, and our goal is to find the percent of each one.

This section equals 12.5/100

A is made of 2 sections
12.5 + 12.5 = 25/100 = 25%

B is made of a half of a section
12.5/2 = 6.25/100 = 16%

C is made of 3 sections
12.5 + 12.5 + 12.5 = 37.5/100 = 37.50%

D is made of 2 sections plus one half of one
12.5 + 12.5 + 12.5/2 = 31.25/100 = 31.25%

What we did is divide the square into quarters then divided the quarters into halves....does that make sense??

3. How many rectangular prisms fit inside a cylinder

Answer: 6 and a little bit.

How....

Rectangle: I dont have the measurements right now

Find the volume of each the cylinder and the rectangle, then divide the rectangle into the cylinder. you will end up with the answer 6. something.

of having a volume of 8.

2. To find the fraction of each
you cut it into 16ths.

Review help

2006-05-31T18:09:00.000-05:00

Well we started probability.

Number of favoured outcomes
_____________________
Number of possible outcomes

example: flipping a coin
you want to flip a heads
there is 2 possible outcomes and you only want 1 outcome.
so it would be a 50 50 chance or 1:2

if you have 2 dice, you multiply the number of sides(6 in total) on one die by 6 on the other
so 6x6=36 possible outcomes
you want a 2
there is only one possible outcome to get 2
so it would be 1:36 chance of rolling a 2.
This is theoretical probability.
Experimental probability is different.

Example: Even though rolling a 2 is 1:36 chance, you still can roll a 2 more than once in thirty six times.
to get the closest to theoretical pr4obability, you just keep on rolling the die.

Next we did algebra

A question I made up was:

A guy is trying to find a perimeter that is 128 feet for his flower bed. But because of his awquard(don't mind spelling) yard, the length has to be 6 feet more that 5 feet less than 2 times the side of the width. What are the length and width of his pretty flower bed?

To answer this go

l=
l=
w=
w=

Too bad exams are over! It was ""fun!""

#1

Expressing fractions into lowest terms means, by dividing the numerator and enominato by the same number.
#2
Improper fractions and mixed fractions are the same because they still reprsent the same fraction. eg. 9/5=1 4/5.

1) I think this is how you do it..

2) You multiply the two numerators and the two denominators...
( You can also cross reduce to make it more simple)
( Dont forget to change it into a mixed number and put it into lowest terms)
3) Multiplying Fractions
This site is a good site that explains how to multiply fractions. It has simple rules at first then it shows you step by step. It has three different games that help you practice multiplying fractions. It also shows you how you can cross reduce. .

4) When you divide fractions you use a reciprical? Or the additive inverse? You flip the second fraction. Then you just multiplty it like you would when you multiply fractions.
5) Dividing Fractions
This website is good for learning how to divide fractions. It gives you the rules and it shows you how to do it with an example. It also has some games that help you practice.

6) In room 41 I chose Tyler's Post because I could read it clearly.
In room 17 I chose Katho's Post because I liked the pictures.
In room 16 I chose Annalyn's Post because she explained everything really good.
In room 73 i chose Ingrid's Post because the animations helped me understand it better.

7) If i was stuck driving behind some crazy driver that only drove at an average speed of 90 km, for 1 1/4 hours, how far would I go?!?

I answered Katho's question..

1. The picture on the left is 5/6 The picture on the right
is 54/30 also 9/5
Like my flags??

2. 1x1=1 1 over 30 okay
5x6=30

3. This site about Multiplying Fractions is from Enchanted Learning. THis site as everything about multiplying and dividing if you click on the links. THis is a good site because you can also use it as learn about other subjects.

4. 1x4=4 =1
4x3=12=3

5. THis is practically the same Site because enchanted learning has everything about learning
6. I nominate Deannia's because hers is the only other one than mine that I see
I nominate Katho I think because that also is the only one I can see
I nominate Me because I only see three and I be one of them HArbuck can I skip the rest of the nominations because no one is going to post tonight so I don't think I will remember to come back and nominate other people.

7.Someone has a lemon murang(don't mind the spelling) pie loded with cherries is cut into 8ths.
You get half of the eight pieces. You decide to share 2/3 of your share. How much pie does each have?

Deannia's Second Fraction Growing Post
1.)OK! Well i know what how do it because you just make pictures. Like for 5/6 you would have it drawn out and 5 covered (cause thats what you have ). Then for 9/5 thats would be improper so you would have to change it to
so that would be 1and 4/5.

2.) Here are some things you should remember when you multiply.
-x numerator x denominator
-mixed numbers are made into improper fractions
-whole numbers are written as whole/1
-look for cross reduction
-all improper answers should be changed into mixed numbers

Numerical Example
2/3x1/3=2/9 all you do is times the numerator by the other numerator and then do the same thing for the denominators
Well i did a picture example at its at the top of the page because i dont know how to move down here and when i try and do something it does nothing.
3.) This website talks about how to multiply do fractions. This site also shows anything else that you would need to know about fractions.This is the website that i chose but i do not get how you link it so yea http://http://www.coolmath4kids.com/fractions/index.html.
4.) Here are some things that you should know when dividing fractions.
-Yours is not to reason why just invert and multiply.
Numerical Example
8 divided by 2=4 Eight is how much you have, 2 is how many groups (size), and 4 is the new group.
My picture example is at the top of the page with the other one i have know clue how to move them done here. Anybody that does can you please tell me.
5.)This website tells you how to divide fractions. It also tells you other things that you need to know about fractions and such. Here is the websites http://www.coolmath4kids.com/fractions/index.html im dint know how to create a link so i just gave the website.
6.) Ok, well i nominate (if thats how you spell it) I think its tylers (8-41)cause it has good pictures and its the only one i see so yea i also nominate umm michael s.(8-17) cause he had good pictures and lots of info,next is ingrid (8-73) cause she had great pictures and very good information, and the last one is annalyn cause she had good pictures and good information. Sorry people i dont know how to make a link so your just going to have too look at them yourselves.
7.) A chocolate bar has 8 equal pieces. You split into into 1/2. How much do you have left?? This is an easy one so you people should be able to get it. Ok well you dont see a picture cause its at the top of the page..I answered tylers (cause i dont see anyone elses) question i just dont know how to create a link to it.
Great well im done, good job for me!!!

2006-05-04T12:30:00.000-05:00

to make a fraction into the lowest term..you have to use a number that can divide the numerator and denomenator...

mixed numbers and improper fractions are mixed fractions because when you divide the numerator with the denominator..

3. press on "practice game" . it helps you on mixed fractions
4. a) if there are 3 apples that your admirer gave you and you ate 1 and 1/2 of the apples how many apples would you still have??

1) Expressing fractions in lowest terms is when you reduce the fraction to the simplest terms possible(by dividing both the numerator and denominator by the same number)..

2) An improper fraction is where the numerator is larger that the denominator, so its like there is one equal whole plus some parts..
A mixed number is pretty much the same thing except the whole is not combined with the actual 'fraction part'..

3)a website that explains how to simplify fractions to the lowest terms.
It also has a little 'activity' you can do to help you understand how to reduce fractions..

4) a) If you have 3/4 of pepperoni pizza and 4/5 of cheese pizza, how much pizza do you have??

b) Jenny has 10 1/2 doughnuts. She gives some guy 5 1/2 of them. How many doughnuts does she have left??

5) Stephanie 8-73, Jeff 8-17, Dhonna 8-16

6)They all have an 'activity' at the bottom to help you understand how to subtract fractions...

Subtracting fractions with diff. denominators
Subtracting mixed fractions

1.
Expressing fractions in lowest terms is reducing the fraction to the lowest it can go.

4/8 divided by 2(both numbers) is 2/4 now you divided by 2 is 1/2. Now that is the lowest it can go because you can't divide any more.

2.
Improper and mixed numbers are the same because they can equal each other

So you have 1 1/3. You take the denominator and multiply it by the whole number. The you add the number you now have to the numerator. So 3 multiplied by 1 is 3 and 3 add 1 is 4 so you now have 4/3. You keep the denominator the same. Now to make the improper fraction a mixed number you see how many 3's are in 4. So there are 1 then how many is left over 1. So now you have your mixed number. 1 1/3.

3.Here is my site for equivalent fractions http://www.aaamath.com/fra42a-idequivfract.html. This site explains how to do equivalent fractions and there is some games so you can practice doing them.

4. You have 2/4 of a pizza and your friend gives you 2/3 more. How much pizza do you have now?

b) You have 2 3/5 of a chocolate bar but you give your friend 1 1/2 of it. How much of the chocolate bar do you have left?

6. Here is a site for adding and subtracting fractions http://www.aaamath.com/fra.html. This site can also show you a bunch of different fractions.

Second Growing Fraction Post

1. Im not really sure what to do.

2. When you multiply fractions you get a new fraction.
If you don't understand my writing because it's not really descriptive look at my numbers.oh yeah.

1/2 x 2/3=
the numerators multiply with each other.
1x2=2
the denominators multiply with each other
2x3=6
so the answer is 2/6......... for mixed numbers, make the mixed number into an improper fraction before multiplying.

3.This is my website for multiplying fractions. This website will show you how to multiply fractions and other stuff on fractions.

4.When you divide fractions you use reciprocal and then multiply.

1/5divided by 2/3
You change 2/3 to it's reciprocal and once the reciprocal is changed you multiply
1/5 x 3/2
1x3=3
5x2=10
3/10

5.Here is a site for dividing fractions.
You can learn how to divide fractions here. You can also learn how to do other stuff with fractions.

7. You have 2/3 of a chocolate bar and someone gives you double that. How much do you have now?

PART 1
May1&2.06

Ouestion1.

I think... Also, u have to divide the numerator and the denominator by the same number, and 1/2 is the smallest term, because you cannot devide any lower..

Question2.
Improper fractions and mixed numbers are the same because, to make a mixed fraction u need an improper one.
Eg. 9/4 <- there are two more groups of 4/4 so the answer will turn out as 2 1/4 because there is an extra 1/4. To turn a mixed fraction to an improper one, you need to multiply the denominator with the whole number, then add the numerator. Eg. 2 1/4 <- 4x2=8+1=9 so the answer is 9/4.

Question3. http://www.themathpage.com/ARITH/equivalent-fractions.htm nt-fractions.htm
This site shows how to make, equivalent fractions, it also tells you how to make them into lowest terms. The easiest way to.

Question4.
A. Harry and Horhay go and buy candy. Harry takes 3/4 of candy from his bag, and Horhay takes 1/2 of candy from her bag. How much candy have they eaten altogether?

B. Earl and Horhay went to the store to buy clothes. Earl buys 20 3/4 dollars in clothes, and Horhay buys 19 9/10 dollars worth of clothes. How much more has Earl spent on clothes than Horhay.

Question5.
Ashley Amantes's, Yvanne Dandan's and Annalyn Aniciete's

Question6.
HERE http://www.themathpage.com/ARITH/add-fractions-subtract-fractions-1.htm
This page shows how to add and subtract fractions, and which common denominator is better to use. Like instead of 1/3 = 30/90, 5/10 = 45/90

PART 2
May 14.06
Question1.
BEWARE! - GUESSING BELOW!

Question2.

Question3.
I dont know if this is really an easy site to help you learn multiplying fractions but i guess its better then nothing. This site wil show you the steps into multiplying fractions. It also has helpful questions that can help you.

Question4.

Question5.
I also dont think this is an easy site to learn dividing fractions. It does show you what the steps are to dividing. Being the same website i used=D i think theres example questions that you can do=D

Question6.
From 8-41=D I nominate Dion - he had a good blog like hyper active stuff, he had nice pics and gifs lol. GOOD JOB DION!
From 8-16 =D I nominate Dhona - she had a nice blog, easy explinations and everything. BERRY GOOD Dhona!
From 8-17=D I nominate Rebecca - she had a nice and easy way to learn the stuff. Good Work BECCA!
From 8-73=D I nominate Aldrin - his blog seems to be the favoured and i dont disagree, his pictures come right at you like 3-D. Nice Work Aldrin!

Question7.
WARNING -- UNDER EXAJURATION AHEAD - dont mind the spelling

If there are lets see... 1..2..3..4..5.. 26 Naruto Uzumaki's (including himself) altogether, and The original puts them into groups of 7. How many groups are there?

I had done Helen's Question - I had posted the answer to her comments aswell=D

it's mothers day!! and you decide to buy your mom flowers. So you go to the flower store and to your surprise you find out there is a mother's day sale! Daisies and lilies for 1 dollar each without tax. You pick out 5 lilies and 3 1/2 daisies. You brought a 10 dollar bill with you how much will change will you get?

So 5+3 1/2 =8 1/2
Its like saying $8.50
So $10.00 - $8.50 = $1.50 or 1 1/2 of the change is yours... i guess=P

Part 1

1.

2. Mixed fractions and improper fratctions are the same because they basically mean the same thing. Say you have an improper fraction of 10/7 you can also write it as a mixed fraction.

10/7 = 1 3/7

3. http://www.visualfractions.com/LowestCircle.html it explains how fractions are in lowest terms.. yaadaa yaadaa yaadaa... with some circle.

4. a) If a basket of apples weighs 3/4 lb. and a basket of pears weighs 2/3 lb. How much do the baskets weigh together?

b) If you have 3 1/2 pizzas and you and your friends eat 2 1/4 how much pizza is left?

5. suuuuuuuuuuurrrrrrreeeeeeee

6.http://www.visualfractions.com/ its basically the same website as # 3 but this time its not on a particular page its the whole website! And its also talks about dividing and multiplying fractions if your interested.

Part 2

3. If your having trouble understanding how to multiply fractions click here.

This site seems simple enough to understand. It even has a game (*cough*) for you.

5. If your having trouble understanding dividing fractions click here.

It seems really easy to understand. It shows you examples and stuff. It has a glance, in depth, examples and workout pages for you to practice.

6. From 8-41 I nominate Dion cuz of his graphics.
From 8-16 I nominate Helen because of her use of pictures and she seems to knoe what she's talking about.
From 8-17 I nominate Rebecca cuz she seems to know what she's talking about.
From 8-73 I nominate Ingrid cuz she seems to know what she's talking about and she has some graphics.

What's a Fraction Growing Post??

2006-05-01T11:56:00.000-05:00

1. 2/4=1/2 because the numerator and denominator both have a common factor- 2

2. they both reprisent a number/fraction larger than one
3. + 6. This is the site which I choose because it not only provides a fraction site, it also provides many of the things we learned this year, so it could be used to review for the exam as well.

4. a)I have a three piece chocolate bar and a four piece cake. I ate 1 piece of chocolate and 1 piece of cake. How much cake and chocolate do I have all together?

b) Terrible Ted took 3 and two thirds of the toast. Ted ate two and two thirds. How much did Terrible Ted have left?

5. I will...
Ok... I posted on Josh and Jenny's in 8-41 and Ingrid's in 8-73

Part 2.

If Dion can make gifs, so can I muahahahahaha...but not quite yet...
1. Later...ok it's later now. So, there's 5/6 eh... Well, first is to make it a whole, which would be 6/6. THis is the same as 5/5. Now you only need to add the remaining 4/5 to the whole and Voila!!! You have 9/5. Hooray! You can also simply use a common denominator which in this case is 30.

2. Numerators get multiplied and denominators get multiplied

3.+ 5.I choose the same site I used earlier because it has all of the stuff we need!

4. "Yours is not to reason why,
Just invert and multiply!"-C. Harbeck, Math Class 2006
So, you invert the second of two fractions involved with the equation and multiply.

6. I nominate Ingrid of 8-73 because she used really good pics and good questions.
I nominate Katho of 8-17 because it has good pics.
I nominate Dhona of 8-16 because she used nice pictures as well and good examples
I nominate Dion cause of his gifs

7. A jelly donut is 3 1/2 inches in area. It is 3/4 jelly. How much jelly is in the jelly donut?

I answered Layco's. it was quite simple. Not because of what you are thinking

If billy has 3/4 of an apple, and sue has 1/3 of an apple how many pices of an apple do they have?
this means 3/4+1/3
3x3=9
4x3=12

1x4=4
3x4=12 9+4=13. they have 13 out of 12 pieces.

The answer to your math question is 2/5 or two fifths. How many different questions can you make with 2/5 as an answer?Try adding, subtracting, mixed numbers, improper fractions etc. The sky is the limit. - There is an infinite amount of possibilties
blogger is acting weird

square: 5/6 to 9/5
Make a whole=6/6 or 5/5, then add 4 fifths. = 9/5

#1. If u have a fraction like 5/15, its not in lowest terms because it can still be decreased, divide by 5 on the numerator and denomenator. Then you have 1/3 which is in lowest terms =
#2. Improper fractions and mixed numbers are the same, suppose you have a mixed number like 4 and 3/5ths, multiply the denomenator by the whole number than add the numerator. So its like 4x5=20+3=23/5ths as the mixed number. You can also go the other way by dividing. Divide 23 by 5 and it goes in 4 times so thats your whole number and the remainder is the numerator =

part 2!
1.so the shape of square has side lengths of 5 and we need 2 show wat the fraction 9\5 is by using the square? hmm seems hard..but it isnt. the whole is 6\6, then its 5\5 then add 4]5 and its 9\5 :p
2. NUMERATORS AND DENOMINATORS GET DIVIDED...
3. L1nk - an interactive math source of how to multiply fractions.
4.as a guy by the name of charbeck once said, yours is not the reason why, oh no, just invert and multiply...i added the oh no :) lol
5.in this website they discuss dividing fractions...the dividing rules...they also have multiplying
6.in our class..dion or matthew, didnt decide who though but either one of those 2 should be in the hall of fame, they finish posts on time and they are pretty good :p aldrin from room 73 because its all good. katho and dhono are also good bloggers.
7. i drank some of my gatorade it is now 4\5th from full, i drink 2\5th more then my friend puts soem of his gatorade and tis 4\5th to the 2\5th, how much gatorade do i have-lol its kinda confusing

1.) When expressing frations in lowest terms you have to make the smallest piece that you can.
6/12 divided by 6/6=1/2 or 6/12 are 1/2
are equivalent but 1/2 is the smallest piece possible. Lowest terms may also be called simplifying or reducing.

2.) A mixed number is a whole number and a fration.
l1/2
A improper fraction is when the numerator has more parts than the denomenator.
5/4 thats improper
These are similar because both are still not a normal fraction. (i guessed here)

3.)http://www.coolmath4kids.com/fractions/index.html
This site has anything you need to know about fractions. It tells you everything you need to know and it explains how to do them. This site can also be used for number 6, cause it tells you how to add and subtract fractions.

4.) a.) Bob was making a cake for his wife. He needed 3/4 cups of milk, 2/3 of eggs and 3/5 of flour. How much ingredenints did he have in total.
b.) Joe has ate 1 3/5 pieces of chocolate cake, then he ate 1 1/5 of ice cream cake. How much more of chocolate cake did Joe eat than he did ice cream cake.

1) Say you have the fraction 4/8 . This fraction is not in lowest terms. To make it into the lowest term you have to find the common factor. The common factor for 4 and 8 is 2 or 4. So once you have found a common factor you have to divide both the numerator and the denominator by that number.

2) Improper and mixed factions are the same because if you have an improper fraction and turn it into a mixed number they are the same but expressed differently.

3) http://www.visualfractions.com/LowestCircle.html

This is a great site if you need help with making fractions in to their lowest term. It uses diagrams to help you understand it more.

a)Georgina and Polly made a race track for their hamsters. Georginas hamster (Mac) only made it 3/4 of the way and Pollys hamster (Frank) made it 2/3 of the way. How far did the hamsters travel all together?

b) Polly and Molly bought the same cherry lipstick. by the end of the first week polly had 3/4 of it left, molly had 2/4 of it left. how much more lipsick did polly had then molly?

This site is great for helping you add and subtract fractions. It tells you what to do when the denominators are and are not the same. Also on the site there is a game, it doesnt tell you how to do the fractions, there are just questions and you have to answer them.

1. Okay i am really not sure what to do but i will do it the way i think i have to.

This is the fraction 9/5

There is one whole which is made of 5 pieces and there is a part of a whole 4/5 so one whole (5/9) plus part of a whole, 4/5, equals 9/5.

2. This is how you multiply fractions

3. This website shows you multiply fractions. It explains it well. There is also a couple games on it to. you could enter in fractions and it tells you how to multiply it.

4.This is how you divide fractions

5. This website shows how you divide fractions. It shows you step by step on how to divide fractions. At the end you have to figure the questions out yourself.

6. ummm i dont know how to get to the other classes blogger. from our class i nominate jenny because she used lots of color and explained things well :P

7. FrankyBob planted some flowers. The next morning the plant grew about 1/8. in the next five days the plant tripled in size. how much did the plant grow all together?

2006-04-28T21:37:00.000-05:00

Question Number 1:

2/4 is the same as 1/2 becuase 2/2=1..4/2=2 there fore they are the same. you have to divide the numerator and the denominator by the same number.Therefore 1/2 is in lowest terms of 2/4 becuase thats as small as the pieces can get.

Question 2:

say you had 7/6 which is an improper fraction. The mixed fraction of 7/6's is 1 whole and 1/6. A mixed fraction equals a improper fraction.How? well... 1 whole multiplied by 6 plus 1 = 7/6 which equals the improper fraction. This how they are the same.

Question 3:

1. As you can 2/4 is the same as 1/2 You can divide both the numerator and the denomenator by the same number that is higher than the #1
2 divided by 2 is 1 4 divided by 2 is 2 so 1/2

2. The one on the bottom represents a proper fraction. One and 1/2
The top represents an improper fraction. 3 halves
They are similar because to make a proper fraction. 3/2 only 2 goes into it once with one left over. 1 whole with one half.
To make it improper. 1 1/2 means a whole equals 2, 1x2=2 and then add 1 so 3/2.

3. http://www.enchantedlearning.com/math/fractions/reducing/ This site shows how to reduce a fraction to lowest terms. It has work sheets that can help figure out the strange world of Alphabets... I mean Fractions!!!!!

4. Since Dion use pie, I'm going to use something even better than it...... Apple PIE! So Tyler is sitting there with 74/3 of pies. While Tyler's Clone is sitting across the room with 2/4 of a pie.
So Tyler decides that His clone is hungry so he gives him half of what he has. How much will Tyler have and his clone after this exchange of Apple Pie?
(Hint) first you should change all the thirds and quarters to one common one.

4b. This time it will be in the form of Pumpkin Pie. So Tyler and his Clone are sitting in there same seats a week later. They both have 50 2/4 Pumpkin pies each. Tyler eats a quarter of his Pie. His Clone decides he's hungry and eats half of his pie. How much pie is left between them and how much did they eat?

2) They mean the same thing or you could say they have the same amount
like: 3/2 is the same as 1 1/2
you can also divide example: 3 / 2 =1.5 so the mixed number would look like 1 1/2

3)I think this site would really help for people who don't understand site has practicing pages so you know what your doing

4.a)Felicity has 1/3 of an apple and Anna has 3/4 of an apple. How much of an apple does Felicity and Anna have all together?
b) If Linda ate 2 1/2 of a chocolate bar then gave her friend 1 1/2 of her chocolate bar how much chocolate does Linda have left?

it was fun i guess.

Yay! First Fraction Growing Post!

2006-04-27T15:51:00.000-05:00

1)Well expressing fractions in lowest terms simply means to get a fraction to its smallest form

2)well.........They are the same for they could be the same number just... written in a different... form

3) http://www.gomath.com/exercises/ReducingToLowestTerms.php
Like its got how to change into lowest terms and cool fraction type calculators for the job! =-) also has other subjects + calculators and places to test yourself

4a)Im going to use one of my favorite things in my problem... PIE! I have 7/4 of a pie (or several pies) and the person sitting next to me only has 2/3 of a pie. I lean over and say that we should combine or pies. He agrees. So how much pie do we have together?

4b)Im going to use pie again! I have...um ...lets see... 4 3/4 of a pie! Yay! So much pie! I got hungry and decided to eat 3 1/2 of my pie in one sitting! i probably couldn't do this but... this is an imagnary scenario! So how much pie would I have left?

No pie was harmed in the making of these questions

5) I answered Kale's questions (8-41), Aldrin's questions (8-73) and Mike L.'s questions (8-73)

2)

Or you could do it as a picture

3)This site has quite detailed steps on how to multiply with everything! Plus im combining two questions in one by saying it also has a dividing fractions section too with all the same cool stuff!!!

4)

Now just with fractions...

6) I nomonate Jennifer of 8-41 because she used very good pictures to explain her questions.
I nomonate Aldrin of 8-73 because he put his whole post on the scrolly thing and used alot of pictures.
I nomonate Dhona of 8-16 because she used pictures for most of her questions.
I nomonate Katho of 8-17 because of really cool pictures.

7) Well... Guess what time it is again!! Thats right!!! Its time for pie!!!
O.K. So one day I had 4 2/3 of a pie. Yay! I eat 1 4/5 of a pie. Yay! All of a sudden I find 2 1/2 pies under the couch!! Yay! Then i go and win a bet and my total amount of pies get multiplyed by 2 1/6!! Yay!! Then I think to myself I wonder how many groups of 6/7 I could make with all pie right now!!! Its your job to figure that out. Good luck, and I'd recomend using a calculator.
and yes i will try to animate this too!

Now I choose to answer Alex's question. (8-17)
If i drove a car for 1 1/4 hours at an average speed of 90km.How far did I get?
First gotta change 90 into a fraction by going 90/1
then change 1 1/4 into an improper fration 5/4
Can you see any cross reduction because i can't!
so...
5 x 90=450
4 x 1 = 4
now how many times does 4 go into 450???
112 times with 2/4 left (or 1/2)
final answer is that u would go 112 and 1/2 km

Today in class we learned how to add fractions.

If the denominator is the same then you just add the numerator
EXAMPLE:

two fifths plus one fifth

2/5 + 1/5 = 3/5 (the denominator is the same)

When you dont have the same denominator you need to make equivelent fractions

Box 1:Parts of a fraction

Numerator
---------------
Denomenator

Box 2:

Denomenator-tells you how many equal sized parts make up the WHOLE.
-it is the bottom number in a fraction
-the denomenator tells you how large or small the parts are.

Box 3:
(a picture of a square with line in the middle)
halves 2=sized pieces

(picture of a square with 2 lines going down)
thirds 3=sized pieces

(picture of a square with a line going horizontally and 3 lines vertical)
eighths 4=sized pieces

As the denomenator gets larger the equal sized pieces get smaller.

Box 4:
Numerator-it is the top number in a fraction
-tells you how many parts of the whole you have
-when the numerator and denomenator are the same (4/4) you have 1 whole.
-when the numerator is larger than the denomenator it is an improper fraction. You have more than 1 whole.

Box 5:

(picture of square with line vertical and 1 half of it is shaded)
1 piece out of 2

(picture of square with 2 vertical lines and 2 thirds of it is shaded)
2 pieces out of 3

(picture of square with 1 horizontal line and 3 vertical lines, 3/8th of it is shaded)
3 pieces out of 8

(picture of square with 1 vertical and horizontal line, all shaded)
4/4 4 pieces out of 4 or 1 whole

5/4= (picture of square with 1 vertical and horizontal line, all shaded) and (picture of square 1 vertical and 1 horizontal, 1/4th of it is shaded)

Box 6: What is larger?

1/2 or 3/8?

(picture of square with vertical line and 1 half is shaded) (picture of square with 1 horizontal and 3 vertical lines, 3/8th of it is shaded)

Make an equivalent fraction

(picture of square with 1 horizontal and 3 vertical lines, 4/8th of it is shaded) (picture of square with 1 horizontal and 3 vertical lines, 3/8th of it is shaded)

4/8th is larger than 3/8th

volume of a trianglular PRISM!

2006-04-18T12:09:00.000-05:00

To find the volume of a trianglular prism you need to multiply base times height times width and divded by 2. eg. If the base of a triangluar prism was 5 cm, height was 4 cm, and width was 10 cm it would look like this.

V=BxHxWx.5
V=5x4x10x.5
V=20x10x.5
V=30x.5
V=15 cm3
____________________________________________________________________
To find the TSA you do this. If the height was 10cm, base was 7cm, and width was 6cm.

1.TSA=height x base
TSA=10x7
TSA=70cm2 x 2 = 140cm2

2.TSA=Base x Width
TSA=7x6
TSA=42cm2 x 2 =84cm2

3.TSA=Height x Width
TSA=10x6
TSA=60cm2 x 2 = 120 cm2

I hope I didn't do it wrong.

Deannia's Scribe for a Cylinder

1.)Find the volume for a cylinder, if the diameter is 8 and the height is 25.
pi r2
3.14(4)(4)
3.14x50.24
50.24x25=1256
Volume is 1256cm3. (didn't know how to do the pi r2 thingy, like how to make it in the computer.)

2.)Find the total surface area for a cylinder. You first have to find the area then you have to find the circumfrence. Were the diameter is 8 and the height is 18.
A=pi r2
A=3.14(4)(4)
A=50.24cm2

C=pi d
C=3.14(8)
C=25.12cm2

You get the total surface area by timesing 25.12 times 18 which gets you 452.16. You would then add your area twice then you would add 452.16 to get your answer. It would look like this.
50.24+50.24+452.16=552.64cm2

S0 your TSA would be 552.64cm2.

to find the surface area of a.."cylinder"
you need to find its 2 bases
you also need to find the "lateral area"
the "lateral area" is the area of the rectangle connecting the two bases...

Heres the rest of my growing post
somethings really wrong with my other post
I cant edit or leave comments
My mom left a comment too so its not working

The realtion between a circle and a square is...
To get the area of a circle Its Pi r r
Say the radius of the circle is one so the side length of the square is one
The area of the circle would be 3.14
the area of the square would be 1
Three squares would be able to fit inside of this circle with a little left over
so u would just have to multiply the area of the square by Pi to get the area of a circle
--------------------------------------------------
Its not over yet...

2)im goin to gues its 5cm by 3cm so it would be7.5m by 4.5m

3)I estimate it would be 9 squares because it looked like it was too blocks down by three for the rec. part and three would fit else where

1) Finding the area for a rectangle.
Area=LxW
Area=3x7
Area=21

2.)Finding the area for a triangle.
Area=1/2 BxH
Area=1/2 4x5
Area=10

3.)The relashionship between the triangle and the rectangle is that the triangle is half of the rectangle.

4.) I have number four done, I just dont know how to put the pictures on blogger.

5.) You would find the area by measuring the the LxW. Basically however you measure triangles and rectangles is how you would find the answer. (have picture just don't know how to put it on blogger)

6.)To calculate the area a 3D shape you need to first add the sides together to get a number then you multilpy that to get you answer then you just add all you final numbers to get you final answer. Yes there is a shot cut you just multipy everthing by two .
(i think not positive)

7.)To find the answer for number 7 all you have to do is follow the same rules for what you did for number 6. (i think not sure though)

finding the rectangle's area you have to multiply the width and the length to get the area.
area= WxL
area= 3x5
area= 15
to find an area of a triangle you have to multiply the height and the base. You have to find the
right angle to find it's height. When it's multiplied it needs to be divided by two.
area= 1/2 HxB
area= 1/2 3x5
area= 1/2 15
area=7.5
the relationship between a triangle and a retangle is that the triangle is half of a rectangle.
(most of the time that is...)
thats all for now. until i find out what to do next.

Day 2

1 way is to calculate the area of each rectangle
Rectangle 1 Rectangle 2
A=lxw A=lxw
A=10x 3 A=8x3
A=30 cm squared A= 24cm squared

TSA= 30+24=54

the other way is to find the perimeter of the full rectangle and subtract the remainder that you don't use

Day3

You can cut of the end which is a right angle triangle and add it to the other side
Then you are simply finding the area of a rectangle

Day 4

O.K. There are 2-3 different sized sides. Assuming that there are 3 different sizes, find the area of one of each, multiply it by 2 and add them together. You can also multiply length, width, and depth to get the TSA(total surface area)

Triangular Prism Question

To solve each triangles area

The first part is that both triangle have the same are. The base is 4cm and the height is 5cm. Usually it is b x h/2, but since both triangles combine to create one rectangle, the formula is just b x h
A=bxh
A=4x5
A=20cm squared

All of the rectangles have different areas. The common one is 10.

First rectangle
A=lxw
A=10x4
A=40cm squared

Second Rectangle
A=lxw
A=10x5
A=50 cm squared

Final rectangle
A=lxw
A=6x10
A=60cm squared

To find the total surface area, we add it all up

20+40+50+60=170 cm squared

170 cm squared is the total surface area!! HOORAY!

Here's my own t. prism

Well, here's the circle part
First of all, your circle's radius must be the same length as the side length of the square
Let's say that the radius is 4 ( just like today)
The side length of the square would be four. to find the area of the square is to well, square the length i.e. multiply it by itself
A=s squared
A=4 squared
A=16 cm squared. THis is the same thing as squaring the radius of the circle. all that would be left to do would be to multiply the area of the square by Pi (3.1415...something or other )

1. The area of a rectangle is found by multiplying its length and width. The formula would look like this: l x w = A

w = 5m L=2m
finding the area...
area= 5xW
area =5x2
area= 10

2. The area of a triangle is found by multiplying its height by its base. To find the height of a triangle look for a right angle. Once you multiply the base and height you divide the total by 2. The formula looks like this:

Base=6
Height=12
finding the area..
Area=BxW÷2
Area=72÷2
Area=36

The relationship between the area of a triangle and the area of a rectangle is that every triangle is half of a rectangle.

5. To find the area of a parallelogram you need to find the height and multiply it by the base. this is different than a rectangle. In a rectangle you have the height and base (due to the right angles in each corner). You multiply length times width. Here are three pictures that shows the relationship between the rectangle and parallelogram.

6. Surface Area is when you have to calculate the area of all the sides of a 3D Shape. Choose a rectangular solid (aka box of somekind) and show how to calculate its Surface Area. Are There any shortcuts??

3.The relationship of a rectangle and a triangle is a right triangle is half a rectangle so the area of a triangle would have to be half the area of a rectangle.

DAy2 : How to find the area of the same shapes two different ways!!!
1.2.
March 16/06

March20/06 : How to find surface area!!

10.2 x 21.6=220.32 that multiplied by 2 because their two side the same.Which then comes to=440.64. then u have to calculate the area of the 2 other sides..so you multiply 10.2 x 7=71.4 x 2 because their are two side the same which then comes to=142.8. Then you calculate the last two sides which are the same again. So you multiply 7 by 21.6=151.2 x 2=302.4. Now you just have to add up those three number which are 440.64 + 142.8 + 302.4= Surface area=885.84

Question 7:

The triangles:

A = Hx Lx W

= 5 x 7 x 5 x 1/2

= 87.5

The higth Depth:

A=L x W

A=5 x 12

A= 60

The Base Depth:

A=L x W

A= 5 x 12

A= 60

The total surface is: 87.5+60+60=207.5

A rectangle had a width of 6 and a length of 14. How do you find the area??

A =L x W
=14 x 6
= 84

A triangle has a base of 5 and a height is 12. How do you find the area??

A = 1/2 x H x B
= 1/2 x 12 x 5
= 1/2 x 60
= 30

The relationship between a rectangle and a triangle is that a right angle triangle is half of a rectangle so the area would be half of the rectangle :)

Day one

Rectangle
A=LxW
A=5x5
A=25

Triangle
A=1/2xBxH
A=1/2x5x5
A=1/2x25
A=12.5

Relation:
The triangles are half of some rectangle

--------------------------------------------------------------------------------------------------------
Day two
4)

One way would be to find the area of eack rectangle:
1st- 5x10=50
2nd- 5x8=40
then add; =90
area=90
OR
whats the total?10x10=100
whats missing? 5x2=10
subtract =90
TaDa!!!
---------------------------------------------------------------------------------

Ok so a parralelogram has a base of 2 and a height of 1
So cut of one of the pointy sides and stick onto the other side to make a rectangle
The Base of the rectangle is 2 and the height is 1
The area is 2
or... just muliply the base and the height without cutting anyhitng.
------------------------------------------------------------------------------

ok a way you can find out the TSA (total surface area) of a 3d rec. prism is you can go:
If L=1 W=2 D=3
Draw each of the sides and fiqure out the area of each rectangles
Two would be
LxW 1x2x2=4
Two would be
WxD 2x3x2=12
Two would be
LxD 1x3x2=6
The tsa is 22
(u multiply each thing by 2 because there are 2 of each side)
Its hard to do still without pics.
-------------------------------------------------------------------------------

To find the Tsa of a triangular prism if the
h=1cm
l=3cm
b=2cm
w=4cm
First fiqure out the area of the 2 triangles.
1/2xBxHx2
1/2x2x1x2
a=4
now...two rectangles are equal
LxWx2
3x4x2
a=24
now the odd rectangle
BxW
2x4
a=8
now add them all up
8+24+2=34cm(squared)
the tsa of the triangular prism are 34cm(squared)
--------------------------------------------------

The realtion between a circle and a square is...
To get the area of a circle Its Pi r r
Say the radius of the circle is one so the side length of the square is one
The area of the circle would be 3.14
the area of the square would be 1
Three squares would be able to fit inside of this circle with a little left over
so u would just have to multiply the area of the square by Pi to get the area of a circle

Thanks very much folks!
--------------------------------------------------
Its not over yet...
extra stuff time!
1)rec l-5 w-4
tri b-5 h-2
or
rec l-2 w-1
tri b-2 h-23
or
rec l-4 w-3
tri b-4 -6.5

2)im goin to gues its 5cm by 3cm so it would be7.5m by 4.5m

3)I estimate it would be 9 squares because it looked like it was too blocks down by three for the rec. part and three would fit else where

We did the 2nd part of Transposing today.

Ya so uh. We used the distributave property to find the answer to the questions. i.e. 4(x+5)=3(x+12)

To get the answer you multiply he 5 in the first brackets by 4(the first number) and multiply 12 by 3(the first number after the equals sign) It should look like 4x+20=3x+36

Now all you do is balance. 4x+20=3x+36
-3x-20 -3x-2

Next
4-3=1 so 4x-3x=1x

1x divded by 1

Next

36-20=16 16 divided by 1 =16

Therefor X=16

Now The actual notes

*There are variables on both sides of the = sign
*Use transposing
*Simplify with the distributing property first
-Solve 1step after cancelling the right variable and left integer

Well, 2day we made another hanburger hotdog thing, i forgot what its called...anyways it was on collecting like terms and transposing!
on collectiong like terms box1 #2 row, it was this....
10x + 75 - 5x = 110
10x - 5x + 75 = 110
+ 5x + 75 = 110

5x + 75 = 110 - 75
-- - 75 ---------
5 5
On row #3 it was...
-Circle the first term
-look for any like terms
*Rewrite the question with regrouped terms
-simplify so that you have 1 variable group and 1 integer group
-solve 2 step equation

on row 4 it was...
32-3x+10-2x+3=100
32+10+3-3x-2x=100
45 -5x=100-45
---- --------
-45 -5 -5

now row 5 it was....
-circle the first term
-find like terms
-solve 2 step
*remember integer rules

NOW THE TRANSPOSING SIDE!

6x+5=2x+13
-2x -2x

4x=8
-- --
4 4

x=2
6x-3=4x+9
-4x+3 -4x+3

2x=12
-- --
2 2
x=6

on row 4 it was....
4(x+5)=3(x+12)
multiply the 4 wit the x and multiply 4 with 5
multiply x wit x and 3 wit 12
4x+20=3x+36
-3x -20 -3x -20
take 3x away from 4x to make 1x and divide that by 1 then take 20 away from 36 and divide it by 1
x=16
------------------------------------------------------------------------------------------------
3(x+7)+2(x-5)=36
3x+21+2x-10=36

5x+11=36
-- -11 -11=25
5 divide 25 by 5
x=25 divided by 5
x=5

now on the last row #5
*there are variables on both sides of the = sign
*use transposing
*simplify with the distributive property 1st
-solve 1 step after cancelling the right variable and left integer!
and im done now hurray!

In math class we made those folded up pieces of paper booklets.

To make them you have to hamburger fold the paper twice then fold it into thirds. When you open it up there should be 12 squares. Then fold the bottom row of 4 up and the top row of 4 down so u should have a 'mouth' that opens up.

On the cover write each of these in a seperate box:

1 step equation using + or -

1 step equation using x or ÷

2 step equations

Distributive Property

Now on the inside of the top 'lip' write of each of these questions in each topic and solve:

1 step equations using + or -
x+6=10; x-7=30

1 step equations using x or ÷
x÷10=30; 3x=24

2 step equations
2x+5=15; x÷3+10=40

distributive property
3(x=3)

On the topside of the bottom 'lip' write the word explanation to each topic:

1 step equation using + or -
1.Isolate the variable
2.cancel using an oppistite
3.balance
4.substitue to check

1 step equation using x or ÷
1.isolate the variable
2.cancel using an oppistie
3.balance
4.substitute to check

2 step equations
1.isolate the variable
2.cancel the interger first
3.balance
4.isolate the variable
5.cancel the multiplier or divisor second
6.balance
7.substitute to check answer

Distributive Property
1. 2 terms inside the brackets
2.multiply the first and second term by the multiplier
3.get rid of the brackets in the expression

Now open up the bottom lip and in the middle row you write each of these questions that have a negitive sign in them and i'll solve it for u ppl.

1 step equations using + or -
-x+6=10 -6
-6
-x= 4
/-1 /-1

x=-4

-x-3=12+3
+3

-x= 15
x= -15

1 step equations using x or ÷
-3x=12/-3
/-3

x=-4

x/-4=7(-4)
(-4)

x= -28

2 step equations

-4x+3=-17 +3/-4
/-4 +3

x= -20/-4= 5

distributive property

-3(x+6)

-3(-x-6)

Now write this stuff under the right topics on the bottom inside 'lip'

1 step equations using + or -

-x=4 is not done
-x means (-1)(x) or -1 times x
divide both sides by -1

1 step equations using x or ÷

whatever u multiply or divide by use the same interger to get a positive variable
-3x/-3 NOT -3x/3

2 step equations

cancel interger
balance
cancel what is attached to the variable
dont forget the interger rules

distributive property

1 negitive sign (odd #) negitive answer
2 negitive signs (even #) postive answer

And thats it really. sry if u wanted sumthing visual mr harbeck but im to lazy to do something like that.

The Distributive Property

3(x+6)- two terms inside the brackets
Multiplied by 3

This means 3 groups of (x+6):
(x+6)
(X+6)
(X+6)

You can solve the distributive property this way:
3(x+6) 3(x)+3(6)
3x+18

e.g.1) 5(2x+3) e.g.2) 3(4x+7)

One step equation solving using multiplication and divison.
1. isolate
2. cancel using the opposite
3. balance
4. substitute
* When cancelling using multiplication or division you still have 1x
E.G.1
3x=24
--- ---
3 3
x=8

When dividing you want to show a number kissing a bracket
E.G.2
x
-- =15
3
^cancel by using opposite
(3)x
----- = 15(3)
3 x=45

make a sentense with the words expression, equation, algebra, 3x+6=14 and 2x-5.
An algebraic expression like 2x-5 is a pattern. There are many answers

An algebraic expression has only ONE (1) answer.

One step problem solving

x+6=9-6
-6
x=3
3+6=9

1)isolate the variable
2)cancel out using an opposite
3)balance
4)substitute to check answer

x+8=20-8
-8x=12
12+8=20

Hint--> when canceling integers you need a result of 0.

-13+y=40+13
+13
y=53
53+13=40

This is different *13-x=12* .

Well mabck in the day, we learned how to solve equations. First Mr. P taught us how to do one step equations with adding, subtracting multiplying and dividing.

Adding 4 + x = 20
4 + x -4 = 20 -4
x = 16

Subtracting x - 5 = 2
x - 5 +5 = 2 +5
x = 7

Multiplying 3x = 24
3x/3 = 24/3
x = 8

Division x/7 = 6
(7)x/7 = (7)6
x = 42
He also told us that when you do 2 or more step equations we isolate the variable and use coefficient first ( aka reverse order of operations)

7x + 9 = 30
7x + 9 -9 = 30 -9
7x = 21
7x/7 = 21/7

x=3

I created a post on the weekend all about the algebra you are doing. I am reposting it for your amusement. Please complete as much of this as you can and leave a comment behind about how you did.

Remember me Grade 8’s. Since I have been gone …only two days you must be missing me. Even if you are not missing me here are some excellent links to reinforce your learning.

The foundation to understanding algebra is to know integers. Here are two links that will reinforce what you need to know.

Try this Integer Quiz. If this is not familiar to you remember your order of operations and try again.

From this link you can see a movie on adding and subtracting integers. It is well done. If this link does not bring up the movie immediately click on the adding and subtracting integer link on the page.

Your first algebra lessons are dealing with words like term, variable, expression and equations.

Here are some helpful resources for you.
Extra help words to expressions
Extra help on variables and expressions

Here are three quizzes to see how well you did.

Substitution algebra
Solving Equations using Addition or Subtraction
Solving Equations using Division or Multiplication

Remember Leave comments to tell me how you did.

Scribes???

2006-02-08T14:06:00.000-06:00

Being a class scribe is a serious responsibility. You need to recapture the class for that day and post it for all to see.

As Richard has said in his posts

” The purpose of a scribe is to inform the reader what your doing and by doing so you relearn what you learned that day making you just a bit more smarter. Also if the reader reads the scribe then they also relearn. To think about it. Scribing is all about learning and learning… etc.”

Try to scribe or comment daily.

im picking up where we left off

2006-02-04T12:16:00.000-06:00

Hi im scribber! yay! ok... what did we do yesterday....

well we had mr Pointon continue to teach us algebra.
and we did that writting the algebricc expressions to english and visa-versa.
I think we also did some tle8 on the computers on the patern relation algebraic translating stuff thing.
Well for all of us that were with mr.P. last year its a review. For those who werent...
3x-8+6=10
this would be read:three multiplied by a quantity decreased by 8 and increased by six is equal to ten
i cant remeber but i think we might have gotten some note stuff too...
coefficient-the number before a variable
variable-a symboly representing an unknown value
constant-a number without a variable
i think there might be more but i cant remember
it was semi medium easy difficult to understand sort of...
the homework was that sheet that mr.P. called the "long paper"
p.s. remember its two sided!
ok i think thats it...
if ive forgotten anything or you have any questions please leave a comment...
ok i declare the next scribe to be....dilley
Thanks all, bye!

Sorry I haven’t been commenting or visiting lately. I’ve been crazy studying for exams… But now that Second Semester has started at Daniel Mac. I’m back. Hahaha. Now that I have seen that you guys are scribing. There are some excellent scribes going on and I assure you they will get better. You just have to push around each other on the blog. That’s the evolution of a blogger right there. You guys have to compete with each other to see who’s the best blogger out there. Hahahaha.

There are plenty of Examples of scribing.

Super (Secret) Scribe

Scribe or What

Scribe Scribles

Yeah there all from the PC30S blog. Hahaha. Well you see. The purpose of a scribe is to inform the reader what your doing and by doing so you relearn what you learned that day making you just a bit more smarter. Also if the reader reads the scribe then they also relearn. To think about it. Scribing is all about learning and learning… etc.

So keep those scribes coming. And here’s a tip. Like in the examples that I posted. Try to use photos to make your scribe look even more better. Hahaha

Some advise to bloggers. You need to be prepared to put a post up to the blog. People are counting on you to keep the scribe alive. If you are having difficulty post a blog and then go back in and edit the scribe.

To the scribes fellow classmates, If the scribe needs to have information added to it, post comments and add information you think will be helpful.

You all are doing a great job. I miss being at school. This is my link to you right now. Keep me informed and I will add comments if I can.

Keep scribbling.

Today in class we corrected the adding integers .

[(2-6)+(-13+65)]-(32+34)=

Some more are:

-2 - (-2)=0
owe 2 owe owe 2
-2 +2=0

54-[23-(-54)]=
54-(23owe owe 54)
54- (23 add 54)
54- 77= -23

Well we also learned about multiplying Integers.

Multiplying Integers Notes

THIS MAY SEEM FAMILIAR TO SOME!!!!!!!!!!

When brackets are touching )( or kissing they multiply

(-3)(-3)= multiplying

-3-(-3)= not multiplying

-3(-3) multiplying when an integer touches a bracket

When multiplying integers

1.. Just multiply

2.. Count the – signs

even number of – signs =positive

odd number of – signs = negative

3(6)(-1)(-1)(-1)(2)(-1)=36

count the – signs EVEN

some answers to the todays homework in book B page 5 I think:

3 (-5) (4)=
3x5x4=60

1 negative sign so it's negative
=-60

(8)(-8)=

1st 8x8= 64
2nd 1 negative
odd so it's -64

ARIES I"M LETTING YOU BE THE SCRIBE SO YOU BETTER DO IT!!! Please!!

Hello! I am the 1st scribe.

In class today we learned about intergers with brackets. There are 3 types of brackets that I know of:{[( )]}.We first did the questions in the brackets. Then we take the answers and make a new question without brackets...example
(1+3)-(-2+1)
1+3=4 -2+1=-1
Now you put the- in the new question.
4-(-1)= 4+1=5

example2
1+[4-(1+2)-(1+1)]
sove( ) first. 1+[4-3-2]
4-3-2= -1. 1+-1=0

I knew this before from grade 7, but thats training wheels!
1 to 5 on page 29 in the pun book is assigned, and so is page 4, a and b.

I'll pick.......Tyler for the next scribe
sorry dion!lol
