I was grading papers and realized that I have a 4th grade class of 31 students. Is this legal? I looked online and could only find the legal class size for grades k-3, which is 1 teacher for 17 students and 2 teachers for 35 students. This class I cannot get much done. Controlling 31 behaviors for 45 minutes is tough. Is there anything that I really can do? How big are your classes? Thanks!
