I attended a small school system where there was one class per grade from Kindergarten through 5th grade. What they called junior high school consisted of three rooms, which were the home rooms for 6th, 7th, and 8th grades. Students moved around among these three rooms for classes from the three different teachers (English, science, and history/social science) and a visiting math teacher who might have had an office somewhere else but didn't have a homeroom. This made an easier transition to high school, which had the full (6 to 8) different teachers and classrooms. There we had 3 different classrooms and 4 different teachers.
