Introduce the concept of area to your third grader with this fun card game. You'll show your child how to determine the area of any object and help him begin thinking in terms of units as you create shapes out of playing cards. Count the cards you use or try applying multiplication to find the total area. Once you've got the hang of the game, assign different values to the cards!

What You Need:

  • Deck of cards
  • Several players

What You Do:

  1. Decide on the unit value of the cards. If you decide on the number 2, each card will amount to two units and players will have to keep this value in mind when calculating the area of the figure you're building.
  2. Have the players take turns placing one card at a time face down on a flat surface. Every card placed down should touch the side of another card. Cards should not overlap.
  3. Every so often, interrupt the game and have one of the players calculate the area of the figure.

Helpful Tip: You may want to guide the players to build rectangles as they'll make it easier to calculate the area. Stop the game at intervals when rectangles have been completed. Then, introduce the formula for finding the area of a rectangle: length x width= area.

Play this game multiple times and assign the cards several different values in order to get as much practice as possible.
