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.

1.10in 8in 5in
2.the angles are the some because they are parella
3.the area is 2x larger because it is not perfect or it would be larger.
1.the new side lengths would be 5in,4in.
2.the angels would stay the same or be the same.
3.original is 2times bigger
1. the new side lengths are 50% smaller than the original.
2.the angles of the new sized paper are the same as the original paper.
3.the area would be quadrupled by the original b/c you x the original area by itself to get the new area.
Math is my favorite subject
1)10in 8in 5in
2)the angles are the same because they are parell
3)the area is 2x larger because it is not perfict or it would not be bigger.
