Area and Perimeter

Third graders have learned to measure the area and perimeter of some shapes. 

 Perimeter is the distance around a shape. We might measure the perimeter of a space if we want to put a fence around it. Third grade mathematicians know to measure each side of a shape and add them together to find the perimeter. 

Area is the measure of space inside a shape. We might measure the area of a space if we want to cover the space with a rug. Third grade mathematicians know to found the squares inside a shape to find the area. Or, to determine the area of a rectangle, you can multiply width x length, similar to the way we multiply rows x columns in an array.

Ask your third grade mathematician to tell you the area and perimeter of the shape below.
