This game uses decks of cards where red cards are negative and black cards are positive. Students draw two cards and determine the value based on whether they are asked to add, subtract, multiply or divide. This game came from a session at AMATYC however I can't find the original. I have added some components.

This is a great way to get students involved and thinking at the beginning of class. I have them get in groups of 3 or 4 and give each group a deck of cards. I have the directions on an overhead and use my large deck of cards to demonstrate how to do the activity. I usually only have to show they what to do the first time when we are adding.

I use this as a warm up as each of the arithmetic operations are introduce.

I typically don't use many games in class, but this sounds really fun. I'd be more like to use this in a pre-algebra class. I might actually do this at the end of class as I expect they might be a little loud and wound up by the end of the game.
