What you need:
- 3X5 note cards (50)
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
