SMMART MUSIC: BUBBLE BEAT
Although simple, this activity will engage your child and help him to practice rhythm and beat.
Lay down a piece of packaging bubble wrap (bigger bubbles are better bubbles) on the floor (or better yet, on concrete...a driveway?) and give your child a meat mallet.
Play a song or sing a simple song with your child and have your child hit out the beat on the plastic bubble wrap. Be sure to beat along to help your child keep the rhythm.
Other fun things to practice on are pots and pans with spoons, or a meat mallet on crushed ice that is on a cookie sheet.
You can also fill a plastic bottle with dried beans and let your child shake out a rhythm.
