With Jane and Joanne
The goal of this game is for pairs of students to work together cooperatively to find missing addends. Teams try to get Tic Tac Toe before their opponents get it.
Each team draws nine (9) cards from the deck. They use those cards in the order drawn to create an addition sentence/problem in which three 3-digit numbers are added.
ExampleThe team figures out their sum and then turns over three of the cards in a diagonal row and displays the sum to the opposing team.
Player 1 turned over these nine cards: 4, 7, 9, 3, 2, 1, 8, 7, and another 2. The problem he creates is:
4 7 9
3 2 1
+ 8 7 2
1 6 7 2
ExampleThe other team now has the opportunity to figure out the missing addends. When they figure them out, they tell their opponents the missing addends. If they are correct, they may put one X mark on a Tic Tac Toe gameboard.
+ 8 7
1 6 7 2
The other team now has their chance to figure out the missing addends in a math problem created by their opponents and to add an O to the Tic Tac Toe board.
Play continues until the Tic Tac Toe game is completed.
