Wiffleball, dodgeball, tag and basketball are fun games to play in gym class. Wiffleball allows kids to play baseball without the large field requirements. The game is played with a plastic bat and ball, which removes the dangers of playing with a hard baseball and a metal or wood bat.
Dodgeball is a classic gym class game that has very simple rules and can accommodate a large number of players. A basketball hoop is a common feature in virtually all gymnasiums, so all that is required is a basketball to set up a game. If a lack of equipment is an issue, tag is simple game that can be played with just players.
