This game is good for older kids. It requires one balloon or beach ball and one hula hoop for each pair of students.

To begin, scatter the hula hoops on the gym floor. Students work in pairs. Partners tap the balloon or ball back and forth in a nonstop fashion. At the same time, they endeavor to pick up a hoop, then tap their balloon through it, and place the hoop back on the floor. Partners keep moving in a different direction to pick up a different hoop. Every time they complete the goal, they score a point. The goal is for the entire group to score as many points as possible in a given time period. This is a very active game that takes physical as well as mental—and social—coordination.
