I believe I have most of my classes under good control. However, my 5th period class contains students who bully. While it doesn't appear or sound like what bullying typically looks like, it's the student who makes fun of a girl who says she doesn't understand what I am doing with a sarcastically toned "I don't understand" sing-songy talkback. Or, it's a girl who thinks she's a tough girl and taunts other boys and girls. It's getting a bit worse over time and I think enough is enough even enough was probably last week or two weeks ago. In summary, a new girl arrived from out-of-state and doesn't know many in the class. The mean girl in the back likes to taunt her with verbal insults and a boy does the sing-songy sarcasm. If both of these students were not in class, my job would be easy. The mean girl was out Friday and hardly any insults were flying around. Seems like the mean boy had no one to play with so his insults to the new girl were not one-upped. Some threats like "I'm gonna throw this eraser at your head" and "Your face scares me" come out of the mean girl's mouth. I've already written her actions in my log and taken her out of the room to talk. I've said I would call her parents if it continued. Something tells me that when the mean girl returns on Monday, it will be trouble. Any suggestions?
