This download includes two separate Tic-Tac-Toe games: Numerical Expressions AND Order of Operations. These are partner games where students select squares and must answer/solve the problems correctly in order to get the square and mark their X or O. Students check one another’s answers for correctness. The first person to get three squares in a row (vertical, horizontal, or diagonal) wins! If game boards are placed in sheet protectors students can reuse them and play multiple times!
