Tic-Tac-Toe Circle Terms
High school geometry can be a challenge! This Tic-Tac-Toe game provides a fun way to practice vocabulary. You'll need to use your understanding of circles in order to conquer squares and earn points in this activity. It's an excellent way to study for a test! Review the "Terms to Know" before and/or during the game for extra help.

Learning circle terminology has never been easier with this fun game. The rules are very similar to Tic Tac Toe, a game that your child is probably knows very well. Best of all, once you're done playing, he'll have his circle words down pat.
