Power of Ten


Learning Outcomes

Learning to subitize the numbers to 10; developing spatial sense through arrays.


Note: This game is usually played with one deck of Power of Ten playing cards. With younger children, you may wish to use half a deck (numbers 1-5 only). Begin by using all the cards to number 5, and then add 10, 9, 8, 7, in that order.

  1. Shuffle the cards and spread them face down on a table or on the floor. Arrange the cards in equal rows (2×10, or 4×5).
  2. Player 1 flips over two cards, one at a time, while pronouncing the value of each. If the two cards are the same, the player retains both cards and continues to take another turn. If the two cards upturned are dissimilar, the cards are then returned face down to the spread of cards.
  3. Player 2 then takes his turn, and flips over two cards, stating the value of each.
  4. The game continues until all cards have been claimed.
  5. The winner is the person who has the most cards at the end of the game.
