You can play hot potato with any ball in any size group. Sometimes, the larger the group, the better. Put the class into a circle and introduce the hot potato, which can be a football, volleyball or kickball. A recreational football made from a spongelike substance lowers the risk of injury. Students may not hold the ball more than three seconds. Count out loud, and if a student keeps the ball longer than three seconds, he is out of the circle. If someone drops the ball, give her time to pick it up before counting. The goal is not to kick children out of the circle, but to help them have fun regardless of whether they can throw the ball two feet or 20.
Freeze is simple but can be effective at breaking in a physical education class. Divide the class into groups of 10 and give each group room to spread out. One student in each group should turn her back on the other nine, who should stand 30 feet from the turned student. When you give the "go" signal, the nine students must quietly move forward. When the isolated student turns her head to look, the other nine students must freeze. Anyone who does not freeze or who falls over is out. The student who reaches the turned student first takes that student's place for the next round.
To play group tag, split the class into two even groups. The students will need flags, jerseys or something else to wear to indicate the teams. When a student tags a member of the other team, the tagged student must freeze. A team wins when all of the other team's members are frozen. To make the game last longer, allow players to tag their frozen teammates to unfreeze them and get them back into the game.
