Reuben Cram pg 92 q.4
4. what are the areas of the three squares shown.
e-30mm. To find the area of this square you need to times the number by itself to get it. 30 is 900mm2.
f-40mm. Now find the area of this square to get 1600 mm2
g-Now for the hypotenuse 50mm. 2500mm2. But now you have to know if it is a right triangle. Add the legs value together to get the hypotenuse. If you get the hypotenuse comment me that it was right and tell me how to paste a pic because I have no idea how to do it.

Deniel's Scribepost from Page 92 Question 15#
Kevin's Scribepost for December 14th 2009
My scribe post was to do number 13 from the textbook , so here it is.
13.A small triangular flower bed has a square
stepping stone at each of its sides. Is the
flower bed in the shape of a right triangle?
Explain your reasoning.
No, the garden is not a right triangle, because the sum of the
areas of the smaller squares (a.k.a the legs) are not equal to the area of the
largest square (a.k.a the hypotenuse) : 4800 + 4800 = 9800.
Warren's Scribepost for December 14th 2009
Here is question #14 that we did in our text book.
Determine which triangles are right triangles
A 9, 12, 15
B 7, 8, 11
C 7, 24, 25
D 16, 30, 34
E 10, 11, 14
Triangle A is a right triangle because 9 to the exponent of 2 and 12 to the exponent of 2 equals 225. And 225 is the area of the hpotenuse of triangle A (15 to the exponent of 2)
Triangle B is not a right triangle because 7 to the exponent of 2 is 49 and 8 to the exponent of 2 is 64, and 11 to the exponent of 2 is 121. But the hypotenuse of triangle B is 121. ( 11 to the exponent of 2)
Triangle C is a right triangle because 7 to the exponent of 2 and 24 to the exponent of 2 is 625. 625 is the area of the hypotenuse of triangle C ( 25 to the exponent of 2 )
Triangle D is a right triangle because 16 to the exponent of 2 and 30 to the exponent of 2 is 1156.
1156 is the area of the hypotenuse of triangle D (34 to the exponent of 2 )
Triangle E is not a perfect square because 10 to the exponent of 2 and 11 to the exponent of 2 is 221. But the hypotenuse of triangle E is ( 134 to the exponent of 2 which is 196)
Bruce's Scribepost, question 6, Dec 14.09
Today Ms.U picked some of us to do a scribe on one of the questions. My question to answer was question number 6.
First leg=25cm squared
Long leg=144cm squared
Hypotenuse=169cm squared
a.Write an addition statement using the
areas of these three squares.
25cm (squared) + 144cm (squared) = 169 cm (squared)
b. What is the side length of each square?
The side length of each square is...
25cm (squared) = 5cm
144cm (squared) = 12cm
169cm (squared) = 13cm
c. Describe, using words and symbols, the
relationship between the side lengths of each square.
a (squared) + b (squared) = c (squared)
short leg + long leg = hypotenuse
That's my scribe PLEASE COMMENT
Question 12 :)
Use the Pythagorean Relationship to find the unknown area of each square:
a) Legs: 20cm2
32cm2
Hypotenuse: ?
In order to find the area of the square attached to the hypotenuse, we have to use the Pythagorean relationship. This means we have to find the sum of the area of the squares attached to the legs of the right triangle. (The hypotenuse is the diagonal line connecting the straight lines of the triangle, called legs).
20+32=52
The area of the square attached to the hypotenuse is 52cm2.
b) Legs: 100mm2
576mm2
Hypotenuse: ?
100+576=676
The area of the square attached to the hypotenuse is 676mm2.
c) Leg: 25cm2
hypotenuse: 90cm2
2nd leg: ?
90-25=65.
The area of the square attached to the 2nd leg is 65cm2.
d) Legs: 12cm2
12cm2
Hypotenuse: ?
12+12=24
The area of the square attached to the hypotenuse is 24cm2.
THANKS FOR READING! PLEASE COMMENT! (VOTE 4 LAURA!)

Question #4.
What are the areas of the three squares shown?
E = 30mm
F = 40mm
G = 50mm
30mm= 60
(30x2) or (30+30)
40mm= 80
(40x2) or (40+40)
50mm= 100
(50x2) or (50+50)
scribepost for dec.14th
questions 9 on page 92
9. a) Calculate the areas of the three squares.
shorter leg is 2cm- area of square is 4cm2
longer leg is 3cm- area of square is 9cm2
hypotenuse is 4cm- area of square is 16cm2
b) Is this triangle a right triangle? Explain.
Yes the triangle is a right triangle because when you look at it there's a right angle. That means that where the two legs meet it's a 90 degree angle.
That is my answer I hope you understand what I was getting at.

How to stop an alien invasion using proportions
First, they wanted to know how to find a unit rate.
~ example: three dinner rolls cost 99 cents.
- Here's one way of doing this:
~ seven identical objects have a mass of 14kg.
then they wanted to know how to get other numbers other then one.
~ example: Delia was payed $35 for 5 h of babysitting. How much should she receive in 3 h?
The last thing they wanted to know was how to find a missing number.
~ example: Determine the missing numbers.
- 60km/3h = ?km/6h
This is how to do it: 3h x 2= 6h so 60km x 2=120km.
- $3/4cans = $15/?cans
All you have to do is: $3 x 5=$15 so 4cans x 5=20cans.
You need to remember what you do to one side you have to do to the other side.
It's good because after they learned everything they decided not to take over earth. Crazy aliens!!

Bruce's Winnipeg Harvest
Mr Harbeck chose people to go and check out things that happen at Winnipeg Harvest. The people he chose from our class were me, Jomari and Tamika. Mr Harbeck also told us to write about our experience at Winnipeg Harvest.
Before we started our tour we met a man called Richard. Richard told us about all the work Winnipeg Harvest does each and everyday. Richard also told us about all the thoughtful volunteers who choose to use their time helping people at Winnipeg Harvest. After all the talking we started our tour, we met a few volunteers(can't remember their names), they told us about what they do at Winnipeg Harvest. We eventually got an assignment on stacking potatoes, our goal was to beat our group's weight(can't remember weight). We stacked 1100 pounds of potatoes and 60 or so pounds of onions. We unloaded 3 big crates of potatoes and half a crate of onions which came to 1100 pounds of potatoes and 60 pounds of onions.
After all that stacking, we went into the main room and had some hot chocolate and some other snacks. Richard came in and told us what a wonderful job we had done. He also told us some jokes, one of those jokes were Whats the difference between boogers and broccoli(children eat boogers). He told us that all the potatoes we had stacked will help 110 families. He told us that his dream was seeing the Harvest close, because when it closes it means that there would be no more hungry people. Richard thanked us for our help and we were on our way back to school.
How I Stopped An Alien Invasion Using Proportions
It was just this morning when an alien was seen... landing.
He is a scout for his planet, and when he sends a signal to his mother ship through his computer... this planet will be no more.
I have managed to get a hold of his computer, but in order to deactivate it I need to answer three proportion questions.
QUESTION #1
Delia was paid $35 for 5 hours of babysitting.
How much should she receive for 3 hours, use a unit rate to find the answer.
Delia should receive $21.00 for 3 hours of work.
QUESTION #2
Last night 30 cm of snow fell in six hours, how long will it take for 45 cm to fall?
First I divided 30 by 2 and I got 15, after that I multiplied it by 3 and got my final answer of 45. In the hour column i divided six by 2 and got 3 then i multiplied it by 3 to get 9.
My final answer is ...
It will take 9 hours.
QUESTION #3
A small gear turns 18 times in the same time a larger gear turns 4, how many times will the large gear turn if the small one turns 54 times ?
Use a diagram to help solve the problem.
In my diagram it shows that if the small gear turns 54 times then the larger gear will turn 12 times
And that people is how I saved the earth.

Winnipeg Harvest
There, we met a man named Richard. He was and awesome guy. He showed us what people did in every part of the building, and told us a few jokes on the way.
The first thing he showed us was this map. It showed us all of the Winnipeg Harvest food banks in Winnipeg. He told us how they need to try and have as much as possible so people who need the food the most can get it easily.
Soon, he showed us what people did there.
He told us about the various people who have worked and volunteered there. He also showed how they sorted all of the donated food. .He also showed how they got all the canned , bottled and broken boxed food. People usually don't buy these even though they are perfectly fine. He then brought us to the freezer which had refrigerated food that they rarely got.
Eventually, we started to do some work. Earlier, we found out that together, we all weighed about 700 lbs. He challenged us to do more than our weight. We sorted the good and bad potatoes and onions. We worked for about an hour. In the end, we sorted at least 1000 lbs of potatoes. This was enough to help 110 families.
Richard congratulated and thanked us for all of our help. He repaid us by treating us with hot chocolate, candy and some chocolate muffins.
After helping them out I felt really good. I felt like I actually did something for our world.Overall, we had an awesome day.
How Warren scared the aliens away from earth.
Yes I got that one right so they gave me one more.
Question 2)
B) Seven identical objects have a mass of 14 kg.
Another one right. They were impressed so the last question they game me was their unsolved only question.The final and last question to save earth from the earth.
Determine the Unit rate
a) two pens cost 94 cents.
That question was the easiest one of all. They were scared of how smart I was that they left as quick as I can blink my eyes.How I stopped an Alien Invasion using Proportion
Question 4 page 67
4. Determine the unit rate.
a) Three dinner rolls cost 99¢.
One roll cost $0.33
b) Seven identical objects have a mass
of 14 kg.
One object have a mass of 2 kg.
Question 6 page 67
6. Delia was paid $35 for 5 h of babysitting.
How much should she receive for 3 h?
Use a unit rate to find the answer
She receives $21.80/3h.
Question 14 page 68
14. Last night 30 cm of snow fell in 6 h. If it
continues snowing at the same rate, how
long will it take for 45 cm of snow to fall?
Determine the answer two different ways
30cm/6h and 5cm/1h
It will take 9 hours for 45 cm snow to fall
Runcel, kris, and Edmil's pay it forward
We saw a movie called Pay it forward In the movie, there was a kid who made up this method of everyone being kind to each other. One person had to do a kind thing to three different people and they have to do it too to spread across the globe. First it did not go well but in the end the kid was being interviewed and his idea to spread happiness and joy to the world was on television for many people to see. After that, the kid stood up for a poor kid being bullied three times. Sadly during the third time, the bully stabbed the kid and killed him but his idea will live on.
What was your act of kindness?
My act of kindness is volunteering at the library.Who did you help?
We helped the librarian at the library.
What did you do?
We did some work in the library like putting away magazines and stacking chairs.
When did you do you act of kindness?
We did our act of kindness after school on December 7
Part 3
How did your act of kindness go?
What happened?
How did you feel?
We felt pretty good doing some work without any rewards.
How did that person react?
Well, she said thank you for volunteering.
did you ask the person to pay it forward?
No, I forgot to tell her to "pay it forward".
How did they react to your request?
Since I did not ask the librarian, I would of not known their reaction to this request.
If you did not ask the people to "pay it forward", how come?
I did not ask to pay it forward because I forgot to tell her.
Part 4
Why is the idea of "pay it forward" important?
This idea is important because it teaches people to be more generous to each other.
Has your act of kindness made a difference?
Well yes it made a difference to many people, those who did not did their responsibility as a library helper and to others who I did not mention. Thank you for reading my post and goodbye!

Question 12 page.61
12. The rate at which glaciers melt is increasing globally. The Saskatchewan Glacier near Banff has receded 1.5 km in the last 75 years. The Peyto Glacier receded 1320 m from 1923 to 1993. Which glacier had the greater annual rate of melting?
Saskatchewan glacier melts 0.02 km in the last 75 years.
1500 m /75 year= 20 m/year;
The Peyto Glacier receded 1320 m from 1923 to 1993. Which glacier had the greater annual rate of melting?
It didn't say how many years did 1320m receded here is how you get it, subtract 1993 by 1923 together you get 70 years!!! Peyto Glacier: 1 320 m/70 year= 18.86 m/year.
The Saskatchewan glacier has the greater rate of melting.
1) What would the recipe look like if it had to serve 10 people? Show your calculations.
so if these is a recipe for 4 people and if you multiply it by 2.5 you will get 10
2) What would the recipe look like if you had to only serve 1 person? Show your calculations.
10 divide it by 10 = 1.

Chantell M's Pay it Forward
Part 2:
I paid it forward by preforming at Lion's Place, with S.P.A.C.E (Sargent Park Advanced Coral ensemble. We preformed for about 20-25 senior citezens and they loved us!
I chose this activity after being shot down with my other attempts. I tried to clean mhy street but it got too cold too fast. Brrr! It's still freezing. Where's my hat and gloves? Anyway.
S.P.A.C.E. and sang and danced for a group of elderly people. We sang various Christmas songs, and danced. My feet still hurt!
I did my act of kindness on Wednesday, December 9th. Like I said I was shot down in my other attempts. I wonder of the bullet holes are still there. *checks* Nope they're gone, all healed up.
I don't have any pictures, which sucks for me... I tried to film it and take a few pictures, but I couldn't find my USB cord to upload them.... I'm sad about that.
Part 3:
The whole thing went pretty well. We even got to do an encore! They loved it! Wait, I said that already right? Whoops...
Each time we stopped singing they clapped and I felt that they really enjoyed the songs we sang. I'm glad we took the time to put smiles on their faces. We even got cookies out of it! Not that they're the only thing I care about. They were good and I'm glad they thought we were good enough to make them happy.
I felt great! The singing and dancing was really fun and the audience really enjoyed it. I hope we can do something like this again. Hehe we even got to get out of class for it. (Um disregard that, please?)
The people reacted well. They clapped nad laughed and smiled, it was a great experience. I'm glad we made them happy.
We left before I could explain about paying it forward. I wish I could of said it though. But, I think they will pay it forward regardless. They're just awesome like that. You agree, because come on, people like that aren't selfish or greedy.
Part 4:
I think paying it forward is important, because it gets people to think of those who need help. Helping others for the sake of helping and not because you've been told to is just - just EPIC! Yeah, that's my word, not stealing.... or else... Just kidding, ot you huh? No? Darn...
I guess my act of kindness made a difference. I mean if we didn't preform I guess the senior citezen's day would have been a little bit boring. Something to make their day or lift their spirits I guess.

Alex's pay it forward
Part 1
What is "pay it forward"?
Pay it forward is someone doing something good or helpful to 3 people and each of those 3 people do something good to 3 other people and each of those 3 people do something good for 3 other people and on and on. My thoughts that I had after the movie about pay it forward (my paragraph) are that Trevor did a really good thing by his pay it forward. One really good thing about pay it forward is that if everybody does their part by paying it forward then it should never end and people should always be helping other people. If a whole bunch of people from different country's watched that movie and they payed it forward and then the next people payed it forward and it kept going that would be really good.
Part 2
What was your pay it forward act of kindness?
My pay it forward act of kindness was I made little baggies and I put a few little treats in the baggies and then I put a sticky note on each of them that said "pay it forward" and at the bottom it said from SP kids and I put them in people's mailboxes.
Why did you chose this activity?
I chose this activity because it would help lots of people instead of just a few people and that would mean more people would pay it forward.
Who did you help?
I helped people on Garfield st. around the little convenience store called Ashcroft's.
What did you do?
What I did was I made little goodie bags and I put them in peoples mail boxes.
When did you do your act of kindness?
I did my act of kindness on Monday December 7, 2009.
Part 3
How did your act of kindness go?
My act of kindness went pretty good except for when my picture was getting taken in front of the house because I was putting the treat in the mail box and I was afraid that the people inside the house would see the camera flash and come out and get all mad.
What Happened?
Well, I started after school when I went and made the treat bags and then I just basically put them in peoples mailboxes.
How did you feel?
I felt pretty good because I know that I did something good for some people and that they might help other people and it might go on and on.
How did that person or people react?
I am not sure how the people reacted because they could have looked in their mailbox at any time and I was their to see their reaction because it was cold out.
Did you ask the person or people to "pay it forward"?
Yes, I did ask the people to pay it forward by asking them on the sticky note I stuck on their baggies.
How did they react to your request?
I am not sure how the people reacted to my request .
If you did not ask the people to "pay it forward" how come?
I did ask the people to pay it forward.
Part 4
Why is the idea of "pay it forward" important?
The idea of pay it forward is important because it is a special act of kindness that is important because if it works then people should always be helping people.
Has your act of kindness made a difference?
I am not sure if my act of kindness has made a difference but by now if it has it has probably happened by now or tomorrow. I really hope that my act of kindness has made a difference because that is what some of this project was about.

Brendan8-16 Scribepost
Today in math class Mr. Harbeck called out people's name's who haven't done a post yet. Unfortunately I was one of them. So, we had to pick 3 questions for either our math homework book or the text book . I chose the homework book..
6. Write out the perfect square root immediately before and after the whole number , and then estimate the square root of the whole number to one decimal place . Check your estimates with a calculator.
Sorry if it's too burly.
7. Martina's painting is on a square canvas with an area of 45 cm2. She needs to buy a frame for the painting. Estimate the square's side length to one decimal place. Show your work .
8. Braden's new game board has 225 small squares. all of the small squares form one large square. How many small square are along one side ? Show your work .
3 Questions from the text book.
So... here it goes....
Homework Book Questions:
1. Ingrid says that she knows that 9 and 16 are perfect squares, and that 10 is not. Is she correct?Explain your thinking.
Yes, Because the prime factors of 9 and 16 repeat themselves. 9 is the product of 3x3 and 16 is the product of 2x2x2x2.10 is not a perfect square because the prime factors do not repeat themselves.
2.Alasie's local football field has an area of 1296 m2. Is 1296 a perfect square? Show your thinking.
Ex:1296=2x2x2x2x3x3x3x3. It is a perfect square because it is the product of 36x36.
3.Brandon's new game board has 225 small squares. All of the small squares from one lagre square.How many squares are along one side? Show your work.

Brianna and Nhea's Pay it Forward
The movie was very sad and touching, one eleven year old boy made a deference. In the beginning it all starts out as a Social Studies project that turns into a world wide movement. To me this one boy had an amazing impact on the people around him. All he did was was feed a homeless man, then that man stopped a women from throwing away her life and from there more people were inspired to help and be kind to one another. In the end the boy, Trevor, was killed for trying to help someone in trouble. In my opinion he went about it the wrong way because instead of involving himself in the fight he could have spoken to the boys or told an adult what was happening. If he tried any of these solutions he might not have died. But over all this movie inspired me to be be kind to people and help them, I think I might even try donating to a charity once in a while. This movie had a very powerful and effective message, the more people that watch it, the more people will be inspired to help out.
Part 2 -
Nhea and I helped kids and adults at Busy Bee Daycare, where Nhea grew up at. We chose this activity because we like working with kids, and because that's where pretty much grew up and I got to know all the adults and kids. One girl even got really attached to me. I helped the adults clean the tables after snack time, I helped the big kids with their beading, and the little kids their reading.
