This is a great activity to practice performing rhythms. Students LOVE getting to create their own melodies and take ownership in this activity. There are many ways to use these materials. I do this activity with 1st grade, but you can certainly modify it to fit many grade levels. Rhythms are pre-selected. Students spin to see what pitches to use. Students record the results by coloring the square the matching Boomwhacker color and then practice and perform their melody. Best of luck and HAVE FUN! Great for centers as well.
