Comparing and Scaling, Math Reflections Inv. 3 pg. 47 - use your book! :)
1a. You would do the number of green peppers divide by the cost of the numbers of peppers to get cost per one green pepper.
1b. Cost divide by green peppers to get cost per green pepper.
Green peppers divide by cost to get number of green peppers per dollar.
1c. Picked Today $1.50 divde 3 green peppers equals $0.50 per pepper.
Fresh Veggie $2.25 divide 5 green peppers equals $0.45 per pepper. Better Deal!
2.(Make a rate table for this problem for Picked Today. Hint- think of the independent variable – green peppers or total cost?)
3a.Write an equation to show the price for n peppers.C = cost, n = number of peppers Equation:

1. A comparison is when you compare two numbers.
2. A ratio is when you take corr. or adj. to find a missing number.
3. A percent is out of a 100 60\100 60%.
4. A fraction is a number over a 100 35/100.
5. A difference is a number minus a number 90-45=35 is the difference.
A1. Ratio
A2. Percent
A3. Fraction 80/150 girls or 70/150 boys
A4. Difference 80 girls - 70 boys = 10 as the difference

Answer the following questions on YOUR blog as a post. Use the same title as mine for your post. Write your answers in complete sentences! An easy way to do this is to copy and paste the questions below onto your post and then put your answers in a different color!1) What has to be the same in order for two parallelograms to be similar?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.I want to create a similar isosceles triangle with a base of 7.5 inches.What should the other side lengths be and why?
1. The angles in degrees have to be the same and have to have parallel sides.
2. To find a missing side length you could find the scale factor then multiple the original number. Also, you could use ratios to find a missing number.
3. The other side should be 10 in wide because the scale factor is 2.5.

For this 10 point assignment - answer the following questions in COMPLETE sentences and use examples to help support your answer. You could copy and paste these questions onto your blog if you need to and then type your answers in different colors. Write me a comment on this assignment when you finish! :)
1) Think back to Mug Wump - how did you decide which characters were similar to him? How did you decided which characters were NOT similar to him?
3) If I used (x, y) to create Mug and I used (4x, 4y) to create a new character, Pug, how would Pug be similar to Mug? What is the scale factor from Mug to Pug? How many Mugs would fit into one Pug (area)?
1. The way I could tell the wumps that were similiar was by being able to mulityple the oringal wump to get the new wump.
2.Pug would be 4x longer and 4x wider than Mug. 16 Mug's would fit into Pug.

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.
