Create your own shapes using colorful blocks and explore the relationship between perimeter and area. Compare the area and perimeter of two shapes side-by-side. Challenge yourself in the game screen to build shapes or find the area of funky figures. Try to collect lots of stars!

Sample Learning Goals

Find the area of a shape by counting unit squares
Describe the relationship between area and perimeter
Build shapes with a given area and/or perimeter
Find the area of an irregular shape by decomposing into smaller, regular shapes (e.g., rectangles, triangles, squares)
Determine the scale factor of similar shapes
Generalize how area and perimeter change when scaling shapes
