Currently, most elementary Music teachers in my district have 10-11 30 minute classes per day, depending on travel to other buildings. Next year, however, we are changing to 45 minute classes on a 3-day rotation. We are told that a full-time position will be 6 45- minute classes per day. Most of us do not have time between classes. I usually have 6 or 7 in a row in the morning, then lunch, then between 3 and 5 in a row in the afternoon, depending on when I travel.
