# Integer War

## Integer War

This is a great way to reinforce what an integer is and help the students to quickly realize how to solve and answer integer problems. Plus a integer game is a better way to reinforce the concept compared to using integer worksheets for kids. Most kids love to play cards.  A standard deck of playing cards is a great resource for reinforcing integer concepts and operations playing variations on the classic card game “War”.

Take out Jacks, Queens and Kings (or ace=1, jack=11, queen=12, king=13, joker=0).

• Clubs and Spades (black cards) represent positive numbers;
• Diamonds and Hearts (red cards) represent  negative numbers.
• Multiple decks can be utilized at one time.

1. Divide cards into even piles for each player (2).
2. Each player turns over 1 card in their pile.  The player with the higher (larger value) card wins both cards.
• OR Each player turns over two cards and add or subtract their values (decide before the game begins).
3. Play continues until one player has all of the cards.
4. In case of a tie (same value) each player then turns over 2 cards.  The 2nd card’s value is used to determine the winner of the cards played.

NOTE:  Can be played with more than 2 players

Variations:

1. Lowest value
2. Highest or lowest absolute values
3. Operations:  As players turn over their card they must perform an operation with the 2 cards played (addition, subtraction, multiplication, division) as designated before the game begins.  The first player calling out the correct answer wins the cards.
4. Each player turns over two cards and add, subtract, multiply or divide their values (decide before the game begins)
