I teach 7th grade English and I'm having a rough time with my homeroom/1st period and 2nd period class. They are my largest class (26) and they will not be quiet. I am constantly having to stop class to keep them on track because of the talking. I have moved students numerous times in the seating chart. My seating arrangement is groups and I'm seriously thinking about changing it back to a horseshoe. There seemed to be way less chatter when it was like that. Also, I always have students forget their book(s)/materials when I have what they need posted on the door every day. It is so frustrating! Transition times between activities is way too long because I have so much chatter and students take so long to get their books/planner out. I am currently doing reteaching of classroom procedures during lunch for the ones who are being particularly talkative. They come down and eat in my classroom and practice these procedures. It doesn't seem to be helping though because I am still having a rough time. Should I bring the whole class down to practice? I need some advice. I am at the end of my rope. Thanks in advance for your advice.
