Plates: Have kids all put a paper plate on their head. Have them move about the room (this can be done to music). If their plate falls, they are frozen and someone else has to bend down without having their plate fall off their head and put it back on their classmates head. The object is to keep everyone in the game. Not only does this activity work on balance, it is cooperative too! This will help keep all students feeling included as well as build the classroom community.
