I have one class that has a handful of boys who joke around with each other inappropriate ways. It's been a problem for awhile, and every time I hear it, I come down hard on them. I've had individual conferences, called parents, issued detentions, etc. I CANNOT get it in their heads that the way they speak to each other is not appropriate for the classroom (ie. momma jokes, fat jokes, etc). I understand this is how they interact with each other outside my room. Whatever. That's their business. I've repeatedly expressed that it's not ok IN MY ROOM. My next step is writing referrals, but I hate to write a referral for something like "Kid A told Kid B his face was dumb." Suggestions?
