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

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
