Area & Perimeter - Each design is contained within a square unit. What is the area and perimeter of their entire design?
Fractions - They write down the fraction for the main color of each square.
Note: Older students could use a math compass to create perfect circles and figure out the circumference of each circle (geometry).
You could use any art medium for this project (paint, crayon-resist art with watercolor, oil pastels, or markers).
