One of the most basic elements of music, rhythm is fun and easy to teach to children, and it's also an essential part of their music education
Rhythm games help children develop fine motor skills, as well as their musical ear.
Try this. Have the leader play different rhythm instruments from behind a screen or blanket.
Depending on their age group, the children can guess the name of the instrument or repeat and/or name the rhythm that is being played (for example, three quarter notes and a rest).
Above all, have fun!
