Getting Ready Activity

Create Compound Figures

1) Roll the color cube, and one number cube. The number rolled will be the quantity of the shape you must use. ex: 4 green triangles

2) Repeat step 1 three times. *roll the color cube again if you get the same color!

3) Use all of your shapes and create one composite Figure. Draw your figure on the paper.

4) Roll both number dice (add together) to get your base(s) and height.

5) Find the areas of your shapes and total area of your figure.

6) Record your information onto the activity page.
