Face-Off! An Integer Card Game
One way to help your child increase his speed and accuracy when solving integer problems is by playing “Face-Off." In five minutes, you and your child can make the game together and begin an enjoyable “study session”—one that may include prizes!
What You Need:
- 3" x 5" notecards (50)
What You Do:
- Cut the cards in half. Divide equally so both players have 50 cards.
- Quickly write integers from 0 through 20 on each set of cards (remember to use positive and negative numbers).
- Shuffle both decks.
- 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).
- Continue playing until all integer cards are used. The player with the most cards wins!
- 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!
