Guess the commandment, a review game:
I’ll have 2-3 kids come up front. They will receive a commandment (like, whenever the Primary sings the word “choose,” spin around). As the primary sings the song the children up front will follow their commandment. The kids singing can also follow the commandment, as soon as they’ve figured it out.
To keep it interesting for Sr Primary I’ll have the kid up front do a much more subtle gesture; fold your arms, flick your hair, lean against the table, pull your earlobe, straighten your tie, etc.
