Use a simple beach ball to enjoy practicing quick addition practice with the whole class or small groups. The 1 page flip chart (made with ActivInspire) practices partners of 10. Use it during Morning Meeting for the class activity, for a quick math warm up, or any time during the day.
Ask your students to spread out across the room and call a name as you toss the ball to them. The color their left or right thumb is closest to is the equation they must solve. It's simple, fun, and helps students memorize these quick tricks.
