About Geometry: Area and Perimeter

Area and perimeter are two of the most practical geometry concepts, used in everything from flooring a room to fencing a yard. These flash cards help students understand the vocabulary and formulas for measuring flat shapes.

Geometry: Area and Perimeter Vocabulary

These flash cards pair measurement terms with their definitions. Students flip cards to learn terms like AREA (the amount of space inside a shape), PERIMETER (the total distance around a shape), and BASE (the bottom side used in area formulas).

How to Use These Flash Cards in Class

Give students graph paper and have them draw three different rectangles with the same area but different perimeters. Then have them label each shape with both measurements. This activity shows that shapes can have equal areas but different perimeters.
