I drew a staff on a piece of paper. Drawing lines on either side of the ruler made perfectly spaced lines for our purposes. I added a treble clef.
We reviewed the note names. Christopher whined and complained about having to practice his notes. Then I pulled out a bag of mini Oreos. Interest immediately increased. Turns out mini Oreos make perfect little notes.
I asked him to put the Oreo on a note. He'd think for a bit, put it on, and if it was right he got one point. When he made a mistake, his score went back to 0. He had to get 5 points in a row in order to get to eat the Oreo. Then we'd pull out a new Oreo and start again.
He did not get tired of this game. He wanted to keep playing and eating Oreos, but I had to cut him off for the sake of his health. By the end of our session, he knew the notes really well. Now we can start on the bass clef tomorrow.
I hope this post is helpful to you in teaching your kids music! I'd love for you to follow along and share!
