Around the Edge: Perimeter and Area

On this Quest, you'll discover…

Measure the distance around a shape and the space inside it.

• Measure and calculate the perimeter of regular and irregular 2-D shapes.
• Explain perimeter as the total distance all the way around the outside of a shape.
• Find the area of regular shapes by counting squares on a grid.
• Find the area of irregular shapes by counting whole squares and parts of squares on a grid.
• Explain the difference between perimeter, the distance around a shape, and area, the number of squares that cover it.
