**Objectives**:

To introduce three mathematical operations -- addition, subtraction and

multiplication -- by using Tic-Tac-Toe methodology

To introduce a new method in using the Tic-Tac-Toe grid.

To present a new method in problem solving.

**Materials Needed**:

Pencils Pieces of paper for computation

Overhead projector Handouts of sample math problems

**Recommended Strategy**:

The teacher will write some math problems on the board to be explained to the

students.

Students will complete problems in computation on the Tic-Tac-Toe board or on

paper. The student giving the first correct answer will get a point. The

points will be totaled at the end of the game.

Place nine students in a square resembling a Tic-Tac-Toe board.

Scores will be kept on a Tic-Tac-Toe board by an "O" or an "X." The team scores

by making a straight line of 3 O's or 3 X's.

The O's will compete against the X's.

If the answer is incorrect, the problem will go to the next team for a correct

answer.

Players will rotate until all have had a chance to participate. Blank Tic-Tac-

Toe symbols are given to students to create new problems.

The overhead projector will be used to introduce problems in finding the missing

numbers. For example, a blank square in the Tic-Tac-Toe grid would require the

answer 15 to the problem "How much is 3 times 5?" These problems will be shown

one at a time to give students a chance to get the right answer or to ask

questions about solving the problem.

**Conclusion**:

Students were introduced to Tic-Tac-Toe problems in addition,

subtraction and multiplication and in finding the missing number.
