This instructional guide and set of three companion workbooks are intended for use in an arithmetic course based on the Tic Tac Toe method of addition and multiplication, which is an alternative means of learning to add and multiply that was developed for students whose learning disabilities (including difficulty in distinguishing left from right and an inability to memorize multiplication tables) have prevented from learning arithmetic by traditional methods. Presented in the guide are the following: case studies illustrating the difficulties experienced by learning-disabled students when learning to add or multiply; basic concepts underlying the Tic Tac Toe method; the six patterns used in the Tic Tac Toe system; techniques for teaching and using Tic Tac Toe math and checking the patterns; and guidelines for using the grids to solve double-digit multiplication and division problems and producing double-, triple-, and multiple-digit multiplication tables. The first workbook contains exercises in distinguishing odd and even numbers, addition, the various positions of the Tic Tac Toe grids, and completing the grids and using them to solve addition, multiplication, and long division problems. The second and third workbooks contain exercises in double- and multiple-digit arithmetic and fractions. (MN)
