Negative Vs. Positive
Objective: To practice adding positive and negative numbers
Materials: one deck of playing cards without face cards or joker (Ace through 10 only), positive and negative number line
NOTE: In this game red cards will be negative numbers and black cards will be positive numbers
- Shuffle the cards
- Deal the cards between yourself and your partner, or split the deck in half
- Each partner will flip over one card. Your job is to find the total of the two cards. The first person to say the correct sum wins both cards.
While we are learning how to correctly add negative and positive numbers, you and your partner will work together to correctly solve the addition problem whenever one card is negative (red) and one cards is positive (black). After you have worked together to both understand and solve the addition problem, you each get one card.
If both cards are negative or both cards are positive the first person to call out the correct sum will win both cards.
How to Win: The player with the most cards when the timer is up wins the game.
What to Write: You should record the sum of the cards you win. You may record this on a number line or on a sheet of binder paper.
