Face-Off! An Integer Card Game

What You Do:

1. Cut 3x5 cards in half. Divide equally so both players have 50 cards.
2. Quickly write integers from 0 through 20 on each set of cards (remember to use positive and negative numbers).
3. Shuffle both decks.
4. Now it’s time to “face-off”. Player 1 should lay down the top 2 cards from his deck face up. Player 1 adds the 2 cards, paying attention to positive and negative signs. Player 2 should do the same with her 2 cards. Compare answers. The player with the highest answer keeps all 4 cards (place in a separate pile).
5. Continue playing until all integer cards are used. The player with the most cards wins!

Tips:

• Next time around, play “Face-Off” to practice subtraction of integers.
• Emphasize speed and accuracy when making and playing the game. The point is for addition and subtraction of integers to become automatic.
• Decide on a fun “prize” for the winner (the winner could choose what to have for dinner, for example, or what to watch on T.V). Never underestimate the motivational power of a small reward!
