Area Builder

Topics

• Area
• Perimeter
• Fractional areas
• Scale factors

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
