FACE-OFF! An Integer Card Game

Submitted by Adrea

What you need:

  • 3X5 note cards (50)
  • Markers
  • Scissors

What you Do:

Cut 3X5 cards in half. Divide equally so both players have 50 cards. Write integers from 0 through 20 on each set of cards (remember to use positive and negative numbers).

Shuffle both decks “Face off”. Player 1 should lay down the top 2 cards from his deck face up. Player 1 adds, subtracts, multiplies or divides (this direction should be given before the start of the game)the 2 cards, paying attention to positive and negative signs. Player 2 should do the same with his 2 cards. Compare answers. The player with the highest answer keeps all 4 cards (in a separate pile)

Continue playing until all integer cards are used. The player with the most cards wins.


  • emphasize speed and accuracy when making and playing the game.
  • set rules up ahead of time, for example Minus 3 if answer is wrong and you get the cards.
  • have the students write the problems and answers with comparison symbols.
  • have a fun “prize” for motivation
