Nine question grid in the format of the game Tic Tac Toe. Each square has a math question. There are a total of 10 games and 10 answer keys. The Tic Tac Toe games reinforce cooperative learning skills as students work together to solve the problems. This activity is useful for review of math vocabulary, a variety of concepts and skills. It is best used as a quick pacer or transition activity. A printable game board can be found on the last 2 pages.
Vocabulary words: point, line, line segment, ray, intersecting lines, parallel lines, perpendicular lines, acute angle, obtuse angle, right angle, straight angle, vertex, protractor; numerator, denominator, fraction, unit fraction, equivalent fraction; perimeter; sum; difference
Concepts: geometry- lines and angles; fractions; part/part/whole computation

To Play: Project the game board so students can see the questions. Divide the class or a subgroup into two teams. One team is X and the other is O. Decide on a captain. Students work as a team to select the problem they want to answer on a given turn and to provide the answer to the selected problem. The team captain tells the teacher which question the team has chosen. The teacher reads the question. Students work together to solve. Only the team captain may give the answer aloud to the teacher. If the correct answer is given the team is awarded an X or an O depending on which team they are on. If the incorrect answer is given then the other team has a chance to answer the problem. Just as in traditional Tic Tac Toe a team wins when they answer correctly a set of problems going across, down, or diagonally.
