Multiple Solutions

Help your students master adding and subtracting integers with this fun, engaging, and collaborative activity! Students play tic-tac-toe with a partner while simplifying expressions by adding or subtracting integers. Player 1 will pick a box (and symbol X's or O's). Both students will simplify the expression. Encourage Player 2 to use their work to check Player 1's work. If they get it correct, Player 1 marks the box with an X or O. If Player 1 is incorrect, Player 2 can steal the box! Students
