Prepare a soccer ball with #'s in every space. Instruct the students to sit on their desks and toss the ball to each other. When they catch the ball they have to multiply the two #'s that their thumbs land on. (example- 2x5=10) If they give an incorrect response or should talk when holding the ball, they have to sit down in their seats. The last person up wins a little something like a pencil. (optional) My kids love it! Everyday they ask if they may play!
