Squares and Roots Bingo! Great way for middle school math students to practice their squares and square roots! Comes with 30 game boards and calling cards. The game can be used as a whole group, small group math centers, or for math intervention.
Cute idea... good way to get them to learn square roots without them knowing it because they know the numbers under the post its! It is very inexpensive and not at all time consuming to make. The only problem I can think of with this would be the postit notes loosing their ability to stick onto the clock's face.
