Explanation/Summary:

Students will pair up and then divide the deck into two stacks with the cards face down. Both players will draw a card from their pile. Each player will read their number sentence and then solve it. Once the answers have been determined, players lay down their cards and determine the winner of the round based on rock, paper, or scissors. If they get a WILD card they may choose rock, paper, or scissors before laying down the card. If there is a tie, then the cards are both returned to the middle of each stack.
