Here are NO PREP Rules You Can Really Use. Post them in your classroom to practice rhythm, pitch, intervals and the musical alphabet. The colorful file is created to match the boomwhacker/bell colors which may aid in singing or playing the major scale, solfege patterns and intervals. Add body percussion, music or rhythm tracks with tempo variations to maintain student interest and provide added challenge.
I haven't even mentioned the daily reminder of classroom expectations which support the PBIS standards as well as Music Standards. Encourage your students to take ownership of their behavior, so that you can just enjoy teaching. Just print and post!
