This is a great song to use with your K/1 friends. It is easy to learn and the bell part can give students a feeling of instant success as they play the melody. The descending melody moves down by step without any jumps. "Falling Leaves" is great for this time of year. Or, if it is too early in the year, just change the word to snow! Later in the year you can bring this out as a station for centers.
I've included paper bells you can copy for the students to practice on as they wait their turn to play and some leaves you can cut out for dramatic effect of falling leaves. However, we both know K/1 friends can be dramatic on their own!
