Gather the neighborhood children together and practice graphing with this backyard tournament!

Head out to the driveway, ball in hand, for a bouncing challenge. Then use those results to make a colorful graph that lets your child compare results.

Your child will "catch" snowballs with each correct math equation she can answer correctly. If she solves a problem correctly, she gets to keep the snowballs.

It's important to be able to add and subtract quickly and accurately, and this activity is the perfect way to practice.
