Tic-Tac-Toe Math

Making metric conversions is a difficult concept to master. Get in some extra practice by playing this Tic-Tac-Toe game with your middle school student. Select a square and perform the conversion inside. For each correct answer, a player can claim a space on the board. Battle for control of the board, trying to claim as many spaces as possible!

What You Need:

• One Tic-Tac-Toe game board (Print this out.)
• The Tic-Tac-Toe answer sheet (Print this out.)
• A pencil/marker/crayon

What You Do:

1. Decide which player will use Xs and which player will use Os.
2. Take turns selecting boxes and solving the conversion problems within them.
3. If a player solves a problem correctly, they may claim that box by putting either an X or an O in it. For each correct conversion, a player also earns 100 points.
4. When a player gets a "tic-tac-toe," by claiming four boxes in a row either vertically, horizontally, or diagonally, they earn an additional 100 points.
5. Play until all of the spaces have been claimed. The player who has earned the most points is the winner.

Math Review:

Use the following information to help with your conversions.

•     1 m = 10 dm     (For example, 4 m x 10 = 40 dm)
•     1 m = 100 cm     (For example, 4 m x 100 = 400 cm)
•     1 m = 1000 mm  (For example, 4 m x 1000 = 4000 cm)
•     100 m = 1 hm     (For example, 4 m / 100 = .04 hm)
•     1000 m = 1 km   (For example, 4 m / 1000 = .004 km)
