Use math flash cards to play tic-tac-toe! Includes two-digit addition and subtraction (without regrouping) flashcards and a tic-tac-toe "board".
How to play: A student "draws" a flashcard and records in their desired square of the tic-tac-toe sheet. Then their partner draws the next card and records it on their desired square. I had the students use colored pencils so it was easy to tell what student was completing what problems.
My class loved having something that challenged them strategically and content-wise! I hope your students enjoy it too!
