Do non-music subs have a hard time in your class? Our classes are just different. I teach middle school choir and music appreciation. Before that, I subbed for a whole year. I learned a lot in other classrooms and in mine. I teach in an inner city school and get many compliments from subs on my organization and structure. I have assembled a few sub letters and such to help you layout what your sub needs to do for the day. Feel free to use everything or bits and pieces. I hope this helps you!
