### Pay it Forward 2011

Welcome to your first 2 Minutes to make a Difference Assignment.  This will start you on your journey to make a 2 minute movie by the end of March.  Here is your assignment.

THIS POST AND ASSIGNMENT NEED TO BE COMPLETED BY DECEMBER 20TH.

Excerpt from the movie:
"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?"

Some possible ideas include:
·        Volunteer at a soup kitchen, hospital, care home
·        Clean up your community/school yard/park
·        Collect new and used toys and donate them to a hospital
·        Help deliver Christmas hampers
·        Make and deliver treat bags for children in hospitals (include pens, notepads, stickers, puzzles, candy, etc)
·        Send care packages for soldiers / write letters to soldiers
·        Become a pen pal with a senior citizen
·        Write ‘Thank you’ notes to people who have helped you
·        Leave cards or notes in mailboxes, on windshields, or hanging from doorknobs
·        AND LOTS, LOTS MORE!!

These are just possibilities. Students are asked to be creative and try to make a difference in someone’s life.

As many of you have noticed there are lots of comments at our posts. It is important to read the comments that you have received. Your classmates and people from around the world have spent time reading your post and leaving you feedback.

Blogger etiquette would have you responding to the comments you have received. A simple thanks and telling them that you have done the corrections they have suggested would be a great starting point.

Now how do you leave a good comment. Most of you are excellent in telling the author how to make a better post. You are great editors and find many small spelling and math mistakes. But does it end there??? Lets try to do more.

Scribes are expected to find a video and a link for their post. You can also leave a video or link in your comment. To do this you will need to use some html code. The code to leave a link is like this

So a link to Sargent Park Mathzone would look like this

Do not forget to use the to finish.

and would look like this after you published it in your comment

Sargent Park.

Try to spice up your comments by leaving links and having conversations with others who have commented.

### Work for October 29

Hi Everyone.  I am sick today.  I have no voice and find it depressing when I try to talk and sound like a snapping turtle.  Hrumph.  Here is the work you need to accomplish today.

Homework Book 20, 21

Show you Know on Page 82
Show you Know on Page 83
Show you Know on Page 84

Copy down any Key Ideas you do not have onto your Foldable from Page 84
Page 85 Do questions 1-13
Page 86 Do Questions 14-18

DO NOT DO THE QUESTION PAST QUESTION 18. THESE ARE FOR TOMORROW.

For all questions SHOW ALL YOUR WORK. It is not good enough to just put 3 as the answer to, What is the Square Root of 9? You have to prove your understanding.

If you get stuck use the back of the book for the answer, copy out the question and fill in the middle or the WORK.

DO NOT GET STUCK ON ONE QUESTION.  DO ALL THE ONES YOU KNOW THEN GO BACK TO THE ONES YOU STRUGGLED ON.

Each room needs three scribes today.

• Scribe 1 Show You Know Page 82, Page 85 Questions 1,5,10,16
• Scribe 2 Show You Know Page 83  Page 85 Questions 2,6,11,15
• Scribe 3 Show You Know Page 84  Page 85 Questions 3,7,12,14
Each scribe must explain how to solve the questions mentioned. These are very important scribes. (New kids only.  no repeat scribes.) Labels are scribepost, Name, squareroots. Remember these scribes are important.

I will be in the Math Help Chat Box periodically during the day.  Leave a message if you need help.

### Sesame Street Rocks

Yesterday someone sent me a Sesame Street video. It wasn't this video but I saw but it peaked my interest...

How can we use videos found at Sesame Street to show our learning.  Simple we are going to rewrite them!!!

Yes I said rewrite.

Your assignment is to choose a video from Sesame Street and rewrite to have a theme of either Ratio, Rate or Proportional Reasoning.  In the video above imagine Ernie is being hussled to buy a ratio.  You could show lots of different examples of ratio and explain what it is.  When Ernie is broke at the end and tells the hussler he bought 9's you could have bought rates. Ernie would then give multiple examples of rates.

The possibilities are endless.

Homework for Tuesday
1.  Choose a group (up to 3 people and one person should have access to a camera)
2. Choose a video from Sesame Street. Any video will do BUT you must rewrite it using Ratio Rate and Proportional Reasoning.
3. Study for your Proportion Quiz on Tuesday.
This assignment will be due on Monday October 18th at 9:00.  More information will follow.  Remember.....
Choose a Video
Choose a group

### Your First Post Math Profile

cc licensed flickr photo shared by charbeck10

Welcome to blogging.  Today I am going to explain a few things about using Blogger.  You will learn as you create a post for me:)

The first thing you do when you blog is to create a title.

The next thing you do is to add your labels.  Separate all labels with a comma.

Now you can type into the body of your text.  Here you will create posts that talk about what
• we did in class,
• assignments like this

Math Profile

In the body of your post you will have to tell me a few things about you and your math learning. Please write in paragraph form and do not just answer the questions.  More than one sentence is better than just one sentence.
1. What do you tell people if they ask you "Do you like math?" What is the best thing that you ever did in a math class.  Why did you like this event?
2. Last year was Grade 7. What was your best unit you studied? Why did you do well in this unit? What unit made you struggle? What could you do this year to not struggle so much?
3. This is Grade 8.  What will you do this year to be a successful math student?  What do you want to learn this year?
4. If you blogged last year, what was your favorite post that you created (add a link). How did blogging help you become a better student? What do you want to do this year on the computer in math class?
This would be my Math Profile.

Hi there my name is Chris.  I am a math student in Grade 8. If someone asked me if I liked math I would say yes it is a subject I like to take.  I am not the strongest student but I love figuring out puzzles and playing with numbers.   I remember a time in Grade 4 when we got to talk about fractions and submarine sandwiches.  This was an activity that really was fun to do.  When we were finished we got to eat the sandwiches.  That is math that I really like.  Yumm

In Grade 7 I really liked the unit on Integers.  I remember all about positive and negative numbers.  We were using bingo chips to talk about zero pairs.  I also remember struggling with fractions.  Trying to figure out the difference between improper fractions and mixed numbers really frustrated me.  Last year I did not do all of my homework. This year to be successful I will use the blog and complete all of my homework.

This is now Grade 8.  I know that finishing all of my homework and using the blog and my friends to help me finish my questions will make me a better student.  I am looking forward to learning Algebra and want to be ready for grade 9.

I was a blogger last year.  One post I did was all about getting ready for the final exam.  I am really proud of this post because I included a video, had images  and explained the topic well.  Many of my classmates commented on my post.  I feel great when I receive many comments.  This year I am looking forward to making my own math movies and working on 2 Minutes to Make a Difference.

### Exam Review 2010 Pythagoras

Here are some excellent Pythagoras Questions.  You should draw a picture to figure out the ABC and have a correct answer.

1. Tony has got his kite stuck at the top of a very tall tree. He knows the string on his kite is 20 m long. When he pulls the string tight and holds the very end on the ground it touches 17 m from the bottom of the tree. If the ground is flat, how tall is the tree
2. Susan is making a jump to ride her bike over. She uses a 1m plank of wood to make the jump, and raises the end 50 cm off the ground with a second piece of wood. How far along the ground from the end of the plank that touches the ground is the second piece of wood?
3. Robert is using a 5m ladder to climb in his upstairs bedroom window. He finds that if he puts the base of the ladder 3.3m from the wall the top leans on the windowsill. How high from the ground is the windowsill?
4. The guy wires holding up an 11m radio transmitter join 2m from the top of the aerial, and are anchored to the ground 7m from the base of the aerial. How long are the guy wires?
5. Tim is standing across a river from Mary. They discover that if they stand exactly opposite each other they can each hold one end of a 5m rope. How long would the rope have to be to reach if Tim moved 8m downstream?

Many of your youtube videos are being watched by other students from around the world.  Please if you get a comment click on their link and return the favour.  Here is a comment on one of your videos

Turnstudent27 from Wingham,Ont: What an amazing video. This video has caught my attention and is making me want to do something about this topic. Why did you guys pick this issue of justice? I had recently done a project on gender discrimination in India, and this video relates to my project. I really enjoyed the beginning of this video it was very unique!﻿ Very well done!

Child Abuse has always been a major issue in our world and I think you reflected on this Social Issue amazingly. Adding the transitions in your video added to it. I also liked how you added the 3 dots in because it﻿ added some suspense to the video. I do not know anyone that is abused I think many children are and it needs to be stopped. This video really made me want to do something about this issue. Why did you decide to pick child abuse as your issue? Turnstudent27 from Wingham,Ont

It would be great to comment on other videos too.  You should comment on our videos and see what the difference was between version 1 and 2.  Great work on your 2 minutes to make a Difference.  I hope you enjoyed the project.
