Place party shapes on the floor in a circle. For example if your theme is Knights the shapes could be shields, swords, and castles. Children walk around circle while listening to music. If the music is loud the children move fast. If the music is quiet the children move slow. If the music stops, the children stop on the closest shape. Young children like to play it this way.
To make it more challenging for older children have 1 less shape than the number of children. Continue remove shapes as the children are ‘out’.
