Pay It Forward

Part 1

What is Pay It Forward?

Pay It Forward is an action of one individual helping another person without wanting or expecting anything back. Pay It Forward is also a movie where a boy first introduce the idea of Pay It Forward, One person helps 3 people without wanting anything back, the 3 people each help 3 others and so on. This movie shows how person can make a difference and how the idea of Pay It Forward can multiply 1 to 3 to 9 and maybe even t

he whole world.

Part 2

What was your Pay It Forward act of kindness.

My group Lizelle, Olivia, and I thought of many ways to Pay It Forward to different people. Our idea was to bake cookies or/and give out small toys like teddy bears, read a book, and also explain to them the idea of Pay It Forward to children in the hospitals either staying in the hospital through Christmas or their for a small period of time. But one of the workers in the hospital told us that we need special permission to do this activity with the children, and that we had to wait until M

onday or Tuesday for us to have the permission. So Instead we decided to donate food to the Christmas Cheer Board for people who are not fortunate enough to have a good meal on Christmas Day.

Why did you choose this activity?

We choose both of these activity so we can bring joy to people on Christmas Day,even though our first idea was not successful the last went very well.

Who did you help?

In our idea of paying it forward we helped the Christmas cheer board on giving people food to eat on Christmas day.

What did you do?

We donated $20 each for us to buy the food and be able to give it to the Christmas Cheer board.

We bought none perishable foods in Dollarama and some that where found in my house. We brought the food on Sunday to the Christmas cheer board, and gave it to one of the workers who thanked us an also gave us a paper (the one on the video) that said thank you!.

When did you do you act of kindness?

We bought the food on December 18, 2010 and brought it to the Christmas Cheer board on December 19, 2010

Part 3

How did your act of kindness go?

Our activity was successfully and hopefully brought joy to the people that will be receiving food on Christmas Day.

What Happened?

After giving them the foods a lady thanked us with a smile on her face and gave us a paper that said thank you.

How did you feel?

I felt a warm feeling and happiness knowing i helped give a family food to eat that they cannot afford

How did the person or people react?

The lady that thanked us had a smile on her face when she received the bag of foods

Did you ask the person or people to "Pay It Forward"?

No we did not. We told the lady that we had a project called Pay It Forward and we explained the activity to her. She is a person that works to help sort the foods and box them, so I think she already paid it forward to many families.

How did they react to your request?

Part 4

Why is the idea of "Pay it Forward" important?

This Idea is very important because it is helping many people and maybe one day the help or kindness will come back to you.

Has your act of kindness made a difference?

Yes I think the activity we choose have made a difference because it gave families food for them to eat and enjoy! <3

Cathlene's Pythagoras Scribepost

5. A right triangle has a side lenght of 40 mm, 75 mm, and 85 mm.

a. Sketch the triangle. Draw a square on each side of the triangle.

b. What are the areas of the three squares?

c. Write an addtion statement with the areas of the three squares

10. A triangle has side lenght of 120 mm, 160 mm, and 200 mm. Is the triangle a right triangle? Explain your reasoning.

The triangle is a right angle because both the legs of the triangle is equal to the area of the hypotenuse.

Legs: Hypotenuse:

120 x 120 = 14400 200 x 200 = 40000

160 x 160 = 25600

14400 + 25600 = 40000

15. Construction workers have begun to dig a hole for a swimming pool. They want to check if the angle they have dug is 90 degrees. They measure the diagonal as shown to be 9.5 m. Is the angle 90 degrees? Explain your reasoning.

Answer: No the hole they dug is not 90 degrees.

a + b = c

6 squared + 8 squared = c

6 x 6 = 36

8 x 8 = 64

36 + 64 = 100

A right triangle has a square attached to each side. Two of the squares have areas of 10 cm and 15 cm. What are possible areas for the third square? Draw a sketch for each solution.

Cathlene's Math Profile

Hello, My name is Cathlene, and I am in Grade 8. If someone asked me "Do you like Math", I would have to say no I do not, because math is one of my weakest subjects in school and because I do not understand most of the units in math. The best thing I ever did in Math Class was grade 6 math because the teacher made it fun for us to learn math, we would play math games that have to do with the unit we where learning about and at the same time we where having fun.

In grade 7 math I think the best unit we studied was Integers and a bit of Coordinate Grid's because for me it was the easiest unit to learn. The unit that made me struggle was Fractions, Decimals, Percent, Probability, Circles, and bit more, it made me struggle because in the beginning it didn't make sense and by the end of the unit it made more sense but then we have to move on to a different unit.

For me to be successful in Grade 8 math I think I would try to understand the subject and start reading my notes and try to do extra math homework if I have time. There is nothing I would really like to learn this year only the things that you are planning for us to learn this year.

I did a few blogs last year and the blog I think I did well in was this blog:http://room43math09.blogspot.com/2010/05/find-mean-median-mode-range-and.html

Blogging REALLY helped me learn the units in math better because you read it in your note and type it down, two things that help me study and remember and at the same time it made math a bit more fun. In grade 8 math I would like to continue blogging again so it could help me in the math units we will be learning.
