2) Describe a way to find a missing side length in a pair of similar figures.

3) I have a small isosceles triangle with a base of 3 inches and other sides are 4 inches.

Play this game with a nearby classmate. It's connect four - with a twist. You must answer the problem correctly and then you are able to place your chip somewhere on the board. Best out of three games. Choose addition, subtraction, multiplication and division before you start.

Assignment #3 - Block 2 & 3 -Will be graded!

This is for a summative grade worth 12 points (3 points each question).

Sometimes when I make copies of worksheets for you, I reduce the the original to waste less paper! (one small thing to help save our planet! :) http://www.ourearth.org/

Let's say that my original paper is 8 inches by 10 inches. I type in 50% to the copier to reduce the paper. Using the math reflection rubric I handed out this year, answer the following questions on your blog (1 bonus point for answering in paragraph form instead of question/answer form):

1) Compare the oringinal paper's side lengths to the new paper's side lengths.
2) Compare the angles of the original to the new paper.
3) Compare the area of the new paper to the area of the original.

Almost there...

You all did a really nice job getting your blogs set up and helping each other out! Special thanks to Josh, Nick, Brittany and Christian for being my blog assistants! If you have time over the weekend, make sure my blog is linked on your blog or that you are following mine. Hopefully all of us will have our blogs up and running by next week!
