Scholastic has published several resource books that are helpful to teachers and care-providers. Circle-Time Activities, by Ellen Booth Church, features no-nonsense, step by step instructions for dozens of “circle-time” ideas, ideal for young children. This book focuses on building language skills as a group activity.
One fun idea found in here is the “Opposite Pokie.” The familiar tune is the same, but emphasis is placed on in and out, and up and down. Adapt it as much as you like with other actions that can be shown by the children.
This is just one of many wonderful resources that can be found on Manhattan Public Library’s Parent Shelf!
