## Tic Tac Toe Math

I have been on a creative streak lately. I LOVE #EduProtocols by Marlena Hebern and Jon Corippo. I LOVE #MathReps which were inspired by Jon Corippo’s 8 p*ARTS of Speech (read the full story). As a result, I have been working on Math EduProtocols. My latest one, that is ready to share with the world and receive feedback, is Tic Tac Toe Math.

This is a sample I created for my class. My intent was to review some basic math concepts while having fun. The rules are simple:

Each player writes their name and chooses either X or O.

1. Player 1 chooses a square to complete. BOTH Player 1 and Player 2 independently work out the problem in the chosen square.  If Player 1 is correct, Player 1 gets the square and circles their symbol (X or O)
2. IF Player 1 is incorrect, Player 2 has a chance to ‘steal’ the square. Player 2 MUST complete the problem correctly AND explain where Player 1 was incorrect.
3. Player 2 chooses a square, even if they stole Player 1’s square. BOTH players must work independently to solve the problem. If Player 2 is correct, Player 2 gets the square. If Player 2 is incorrect, Player 1 has a chance to ‘steal’ the square. Player 1 MUST complete the problem correctly AND explain where Player 2 was incorrect.
4. This continues until someone wins or all squares have been completed.

I tested it out on my students. They liked it and had some good feedback. Some wanted ALL algorithms. Some wanted harder problems. This was a fair statement as I purposefully chose easier problems. I wanted to hook them before going all in. Two students worked on the middle square together and decided that they both claimed it; that worked for me. Overall, it was something that they all enjoyed.

The set up of the problems was purposeful. The four corners are meant to be easier problems (DOK 1). This allows all students success. Those that are between the four corners are meant to be a bit harder. Finally, the center square is to be the hardest. A challenge problem. A player can still win without choosing the challenge problem. I did like the modification my students came up with for that middle square. It takes the pressure off one particular player and allows for collaboration, problem-solving, and communication between players in a friendly manner.

I have created a template with directions and the above sample. Feel free to copy and create your own. I would love to hear how you are using it and how your students feel about it. What modifications have you made? Please share!
