All you need is a toy mouse or another small animal. Hold the toy in your hand as you say:
Mousie, mousie, how quiet can you be?
When I clap my hands, 1-2-3, we shall see!
Clap your hands 3 times, and then pass the toy to a child who is standing/sitting quietly. That child holds the toy, walks around the room, and passes it to another quiet friend. The game continues as children pass the toy to friends who are sitting quietly.
*Use seasonal toys, such as a jack-o-lantern, snowman, or leprechaun.
