A heap of balloons and a flock of birds are on a collision course in the sky! Challenge your child to determine the exact locations that the birds and balloons will meet. She'll simply insert some "x" values into the linear equations that have been given, and plot coordinates on the included graph. Not only will she build a basic algebra foundation, but she's bound to have a ball—or rather, a balloon!

Looking for more coordinate practice that takes place up in the air? Help these pilots plot their course!
