Integer War is similar to war and is played with a standard deck of cards. The red cards represent negative integers and the black cards represent positive integers. Aces are one's. Black face cards are +10 and red are -10.
1. Distribute the cards equally so each player has half the deck.
2. Each player lays down a card face up.
3. Players mentally add the two cards and the first person to yell out the correct answer wins!
4. The goal is to get all the cards!
Variation:
- You can follow the steps above with integer multiplication.
- You can use the subtraction mat that I created here for integer subtraction.
- You can use the division mat that I created here for integer division. This is really difficult because you may have to come up with decimals mentally. I also made my students know these bench mark fractions from memory so this was a great way to integrated fractions, decimals, and integers!
