This video was made by Gelli, Hanbit, (Tracy) and Maeddah. This video is about Canadian Poverty and it shows what people are going through. And how it affects many other people all around the world. We hope that this video has touched you guys like how it touched us while we made it. Please think how you can stop poverty and take action. Well here's are video, enjoy it.

Adding Fractions:
1st : Find a common denominator.
2nd : Add the numerator to a numerater.
3rd : Add the denominator to a denominator.
Last : Simplify it. (only if possible)

Vocabulary:
Hypotenuse - The hypotenuse is on the opposite of the right angle and is the longer side of the triangle.
Legs - Are the shorter sides of the triangle.
R.A.T. - Right Angle Triangle.
Theorem - A theorem is a demonstrated statement that has been proved or needs to be proven. Pythagoras' theorem was a² + b² = c² .
Greek - A native or citizen of Greece. and that's it for the vocabulary.

Pythagoras was a Greek who lived 2500 years ago. He was an "uber" smart mathematician. He is the one who came up with the theory of a² + b² = c². Pythagoras is important because his mathematical theories and formulas are still used today.





This shape is a right angle triangle (R.A.T.). The legs are the shorter side of the triangle (a and b). Across the right angle, is the hypotenuse. The hypotenuse is always the longest side. The hypotenuse is c. The formula for a right angle triangle is a² + b² = c². a can either be the vertical line, or the bottom line. The same goes to b.

This shape is a square and it has four right angles. The lines on the square just help you see that its equal on all sides. All together the square equals 360 degrees and to get that all you do is time 90 degrees by 4 which is 360.




You need to find out how long each side of the square is. Then that will give you side 'a' and 'b' for the triangles since they're both the same length. So then find the length of the hypotenuse, which is 'c'. After you find that out you can now label the triangle and add up all the sides to find the perimeter.

Today in class, Mr.Harbeck gave us a white worksheet to complete. We had to pick two questions for part 1 & 2, and do every question for 3, 4,5. We had to draw algebra tiles to solve the equations. Then add and make sure you read the questions carefully because they don't all ask you to draw algebra tiles, but you do need to VERIFY!


"Thanks for reading my scribe, I choose.. CASEY B"

For my act of kindness, I'm thinking of helping anonymous people like the elderly, children, and the homeless. Some of my ideas to pay it forward was to help at an old folks home, help at the Children's Hospital, babysit for free, volunteer at a Christmas cheerboard, shovel someone's driveway, do community service, do chores at home without being told, and to donate money, clothes, or toys. I thought about going to the Children's Hospital or Calvary Place. I'm going to pay it forward during the break.





What I ended up doing was I made cards with Abby, Alyanna, Carrie, Gelli, Sutchai, and Arielle. The cards we made were about paying it forward, explaining what pay it forward is, why we are doing it, and how others can help. We all participated and equally shared the work by thinking, writing, drawing, and coloring.

On the front of each card said, "Pay it Forward" and to read before thinking to even throw it out or something similar. If you think about it, do you think you'd read something handmade made by anonymous people in the mail? Would you throw it out without even reading it? I honestly probably wouldn't take the time to read it, but maybe if it said something like, "Please read before throwing out." or "Before you even think of throwing this out, please read it." I'd probably read it. We also drew pictures on the front of the cards like flowers, cartoons, and forward symbols like the ones on a VCR. In the inside of the cards basically covered the who, what, when, where, why, and how. We also drew diagrams of one person paying it forward to three other people, each of the three paying it forward to three other people, and so on. We showed how it can spread quickly to many people and around the world. We also attached a lollipop to each of the cards to show our appreciation to pay it forward. We put the cards into mailboxes of unknown people.

I felt that I have done a good deed by spreading the message to others. I also felt like watching someone open their door and read what we had left in their mailbox and how they would react. I think the people whom I have given it to would have probably had a happy feeling reading the card and had a smile on their face wondering who had made the cards. I'm hoping that the people who received the cards actually read it and don't tend on throwing it out. I hope that they also pay it forward to help us spread the message.

Do I think that one person can make a difference? I know someone can make difference, it may not be a huge difference like to stop global warming but everyone counts. Even if that difference is very little, it will continue to grow no matter how small it may be. It is almost like a tree, it'll start out small and it will take time for it to grow, but in the end it is a large beautiful tree, and all the waiting really paid off. I think if you really believe in yourself that you can make a difference in our world and that you never give up, you will make a difference. No matter who you are. Age? Size? Culture? Ethnicity? That all doesn't matter, what matters is what is in you! Every little difference can make a HUGE DIFFERENCE! EVERY PERSON COUNTS!

Integers ..
Today, we had our second day of learning Integers. We didn't really talk about anything. Except for the yellow workbook we have. We have to do pages 41 and 42, there are about 100 questions.
There is three sections to it A. 1-10, B.1-24, and C.1-75. For A. 1-10 you need to answer it with number lines. B. 1-10 you need to answer them with "have and owe", and 16-24 it is your choice, you can answer it however you want. For C. 1-10 you have to answer it with pictures (pictorial), and 11-75 is your choice be free to answer it however you want.

Here are three examples from each section. (A,B,C)

A.
1. 7 to the right, 3 to the left.



B.
1. (+4)+(+3)= +7
have 4 and have 3 = +7


C.
1. (+10)+(+3)= +13



There is my three examples for each sections. This is all we learned for today. (Oct.20,08) Don't forget to leave me a comment.
So for the next scribe im choosing SUTCHAI WONDA SANA ! :) Have fun SUTCHAI! Look who's gonna have to suffer :P.
