Tic Tac Toe Math is a skills practice game which combines a math focus (decimal addition and subtraction for this session) with the old-fashioned game of Tic Tac Toe. This can be used as a whole class participation using a document camera, alternating X and O participants or splitting the class between X and O. Students must correctly answer the square selected to earn the X or O. It may also be used as a quick skills practice sheet.

Ten games, with keys, included. Games include general addition and subtraction, inequalities, word form addition/subtraction, missing digit solutions, and "My Favorite No." A helpful resource to reinforce addition and subtraction operations, especially decimal place value, with a focus on detail and the importance of accuracy.
