File folder math games are fun and easy to put together. You simply need manila file folders, markers, stock paper, coins, and clear contact paper. Draw a game board on the paper. You can create it in a square or a design, just be sure to have a beginning and an end. Write some math problems in the squares. For example, 4 + 2 = 6, so advance 6 spaces. Include some subtraction problem like 5 – 3 = 2, so go backwards 2 spaces. Decorate the game board and attach it to the file folder using the contact paper. Enjoy!
