Find a deck of cards, and get ready to practice your addition and subtraction. Battle for points by flipping over cards and finding their differences. Add up your total earnings to see who wins! This game is great for both home and the classroom, as children can play it independently or with an adult. Players support each other as they figure out the answers to subtraction problems, and they are soon able to find differences more quickly as the pace of the game increases!

What You Need:

• Deck of cards
• Pencil and paper for each player/team (to keep score)

What You Do:

1. This game is for two players or teams. Decide who is on team Red and who is on team Black.
2. Shuffle the deck of cards and place it face down.
3. Aces will count as one, faces cards count as 10, and all other cards equal their face value.
4. Each team takes one card and flips it face up. If the color of the cards is red, the red team gets the difference of the value on the cards. If the color of the cards is black, the black team gets the difference. If there is one red and one black card, both teams get the difference. For example, if a two of hearts and a ten of spades are turned over, both teams get 8 points, the difference of these cards.
5. Each team should keep track of their own score, thereby practicing their addition as well.
6. Play continues until the pack is depleted. The team with the most points wins.

Variations:

• Change the scoring rules so that teams receive the sum of the cards.
• Change the scoring rules so that teams receive the product of the cards.
• For younger players, adjust the rules so that only one point is earned each round. Record scores with tallies.
• Play until one team reaches a certain number of points (e.g. 100).
