Tic-tac-toe is a favorite of my oldest son's. We have passed many minutes playing the age-old game on children's menus at restaurants while we waited for our food.
To add a little math practice in, I made four tic-tac-toe game boards with fraction addition problems. To start, these boards only have problems with like denominators that only add up to 1 or less.
Download the boards I made for free from Google Drive here. There's a blank page of boards too so you can write in your own problems!
I printed the boards on cardstock and then slipped them (front and back) inside a plastic sheet protector. I trimmed it down and grabbed two different colors of dry-erase markers.
No sheet protectors? No problem. You can also laminate the cards or place a clear plastic report cover over the pages so the dry-erase marker wipes clean and you can reuse them again and again.
This game of tic-tac-toe has no Xs or Os. Instead players select their space on the board, solve the fraction addition problem and mark the spot with the answer in their colored dry-erase ink.
Play alternates between players until either the board is filled or one player gets three problems completed in a row (horizontally, vertically, or diagonally).
