Hoops or jump ropes, one for each participant; music and a player that pauses.
This is a great activity for groups of 2-6 children and a non-competitive alternative to musical chairs. Gather up several hoops or jump ropes tied in a loop, one for each child and adult. Place a different instrument (maracas, drums, home-made shakers, xylophones, etc.) in each hoop. Have each child choose where he or she wants to begin playing and start the music. Stop the music and have the kids put down their instrument and find another hoop to move to to play. You can do this until everyone has had a chance to play each instrument or until they get tired of this game!
