Quick and easy game to reinforce Absolute Value. All you need is a deck of playing cards!

Black is positive; red is negative.

 Using a deck of playing cards, with Face Cards and Aces
removed, divide the deck between both players.
 Each player will lay a card face down at the same time.
 Decide which card has the highest absolute value. The player
who placed that card down wins that round and gets both
cards.
 Repeat until all cards have been played.
 The player with the most cards wins the game!
 Shuffle and play again.
