Description
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
