Alyshia's Textbook Questions pgs 98-100 # 6, 14, and 17

6. What is an example of a whole number that has a square root between 9 and 10? 14. Alex is thinking of a number.

a) What number could he be thinking of?

a) What is the area of the picture?
b) What is the area of the board?

c) What are the dimensions of the board?

The pythagorean relationship is the relationship between the lengths of the sides of a right triangle. The sum of the areas of the squares attached to the legs of a right triangle equals the area of the square attached to the hypotenuse.



#2 Solve for the missing side length



#3 Is this a right triangle? Prove it!!!!!

No this triangle is not a right triangle because the sum of the areas of the two squares attached to the legs do not equal the area of the square attached to the hypotenuse.

Alyshia's Pay it Forward

Part 1

“You see, I do something real good for three people. And then when they ask how they can pay it back, I say they have to pay it forward….. To three more people. Each. So, nine people get helped. Then those people have to do twenty-seven.” He turned on the calculator, punched in a few numbers. “Then it sort of spreads out, see, to eighty-one, then two hundred forty-three, then seven hundred twenty-nine, then two thousand, one hundred eighty-seven. See how big it gets?”

What is "pay it forward?" "Pay it Forward" is when one person can make a difference, by doing something nice for someone in need. Then you ask that person to do something nice for someone else and after it will hopefully keep going on.

Part 2

What was your Pay It Forward act of kindness?
My Pay it Forward act of kindness was making goodie bags and giving them to the children at the children's hospital. Did you know that every day there is at least one kid that gets treated for cancer?
Why did you choose this activity?
I chose this activity because I wanted to make the children at the children's hospital more happy by giving them toys to play with because they don't deserve to be there but we can't help that, these things just happen.
Who did you help?
I helped children because now they won't be so upset about being in the hospital because they now know that people care about them and respect them by donating toys or even money to them.
What did you do?
I made goodie bags that was filled with toys for the children at the children's hospital.
When did you do you act of kindness?
I did my act of kindness on Monday, November 14, 2011 @ 8:00 AM.

Part 3

How did your act of kindness go?
My act of kindness I think went pretty well and I liked doing this act of kindness because I love being with kids and helping them. It was also very fun to do.
What Happened?
Me and my friends made goodie bags for the children at the children's hospital and while we were doing that we took pictures to put in our scrapbook and in our video. In the end we went to the children's hospital and gave the lady from the front desk of the children's hospital the goodie bags. We couldn't give it to the children in person because they needed their privacy.

How did you feel?
I felt excited at first when I first found out that we had to do a "pay it forward" project and the first thing that came to my head was to do something for the children. After when I actually started doing the work it was really fun but at the same time sad knowing that there are a lot of children with medical conditions.

How did the person or people react? The lady from the front desk was very happy that we made goodie bags for the children and thrilled when she saw how many bags we actually made and brought. She was also very happy about how many grade 8 students from Sargent park actually came and brought stuff to.

Did you ask the person or people to "Pay It Forward"? Yes, I did ask the lady to "pay it forward" and she said she will because she wanted to see the "pay it forward" move around the world and making other people's lives better.

How did they react to your request? They were thrilled with us giving goodie bags to them and surprised on how many we actually made and brought for the children.

Part 4

Why is the idea of "Pay it Forward" important? The idea of "pay it forward" is important because not only in our community but around the world people notice that when you "pay it forward" it makes a difference to someones life. When you "pay it forward" to 3 people you change their life some how and those 3 people will do the same. It also is important because anyone can make a difference in the world and make someones life better. Doing this also lets others know that there is a lot of people around the world that suffer with their lives.

Has your act of kindness made a difference? I think my act of kindness has made a difference because now the children will always have something to do and play with. Because none of those children deserve to be there.

Here is the link to the children's hospital in case if one of you would like to donate to the children too.

I hope you like what me and my friends did for "pay it forward" and I hope you will help donate to the children at the children's hospital because no one deserves to be at a hospital and miss out on what life has to offer.

Alyshia's Graphing Post

1. Different graphs may provide different information and display certain types of data better, like:

Bar graphs: are best for comparing data across categories

Double bar graphs: are best for comparing two sets of data across categories

Circle graphs: are best for comparing categories to the whole using percents. The sum of all the percents in a circle graph is 100%

Line graphs: are best for showing changes in data over time

Pictographs: are best for comparing data that can be easily counted and represented using symbols

2.

The 3 ways that a graph can be misleading is:

1. distorting the scale


2. distorting the size of bars


3. distorting the visuals
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   

2a) The following chart shows Pizza Sub Sales over a month. What 2 graphs would show the information accurately? The line graph and the bar graph will show the information more accurately.
2b) If you were selling Pizza Subs would you continue? How does your graph explain your answer. I would continue selling pizza subs because over the weeks the sales have been getting better and better.


3. Below you see 2 different examples of graphs showing healthy choices sold at the canteen. If you had to convince Mrs. Mota that we should continue selling healthy choices which graph would you choose? I would choose a line graph because it easily shows how the sales of the healthy choices at the canteen are getting better.
4a) Change each graph so that your information looks even MORE impressive. You may not change the data just the graphs.


My graphs that I think make the information more accurate.
