Group Activity Cards

 Use groups of 3. Materials: 15 index cards, cups and counters, equation mat Follow the Leader

Copy each equation below onto an index card. Shuffle the cards and place them in a stack face down on the table.

 Equations to put on cards: x + 4 = 3 ans: x = -1 x + 6 = -5 ans: x = -11 x + 7 = 9 ans: x = 2 x - 5 = 4 ans: x = 9 x - 2 = -3 ans: x = -1 x - 8 = 6 ans: x = 14 5 = x + 8 ans: x = -3 7 = x - 3 ans: x = 10 9 = x + 6 ans: x = 3 x - 10 = -1 ans: x = 9 x + 3 = -5 ans: x = -8 x - 2 = 11 ans: x = 13 6 = x - 7 ans: x = 13 x + 2 = -13 ans: x = -15 12 = x + 10 ans: x = 2

Round 1 begins with the first player drawing a card. Player 1 should not show this card to the other players, but instead represent the equation using the cups and counters. Player 2 then writes down the equation that player 1 has modeled. If represented correctly, player 1 awards player 2 one point. If represented incorrectly, player 1 indicates and corrects any errors, and player 1 receives one point. Finally, player 3 must solve the equation. Player 1 checks the answer with the answer indicated on the card, awarding one point for a correct solution. If player 3's answer is incorrect, player 1 receives one point.

Round 2 begins with player 2 drawing the card, player 3 writing the equation, and player 1 solving the equation. Play several rounds using the above procedure until all cards have been used. The player with the most points at the end of the game wins.
