We used this one in class this year. It is similar to war and can be done with a regular deck of cards (take out face cards), except the red cards are negative and the black cards are positive. You can do comparing integers by just flipping over one at a time, or you can add/subtract/multiply integers by having each person flip over two cards and find the sum/difference/product. I hope this makes sense. Also, if you do a web search for card games, you will find others. You could also do a variation with dice or dominoes if you feel like being creative.

Good luck!
