For that age a great thing would be a music circle time! Get some fo the children’s hymns and teach them to sing! Circle time is an easy way to handle kids that age. You can use different colored mats for each child and have them sing with you! Alsoif youswitch t a game like head shoulder knees and toesthey are all right in front of you to see what they need to do!
Sounds lik you’ll have blast!
