Hello, This is my first post and the subject is basically why I signed up to write on these forums. I sub frequently at this middle school, mostly for the seventh grade. Most of those classes there is this seventh grade girl who rarely does her work and challenges my authority a lot. I started being lenient with her because she went through tough times but gradually she developed an attitude and I've been getting tougher. She has to toned it down but recently I had an incident with her. I was subbing for a math class. In the beginning of the period, after the bell rang, she pops in and takes a student out of class without my permission. The girl she takes gets in trouble for that. Later on, as I was helping students in an already difficult class (lots of kids with a sub in a small room is a recipe for a headache), she comes in (I don't have her during that period) and interrupts me. I tell her to get to class but she begs me to let her in to get her pencil. I roll my eyes and let her in but she goes to hug two of the students and skips around the room and taunts me. She then leaves but before going into the hallway she kicks the door stopper away and slams the door behind her. I close the door and lock it. A few minutes later I hear knocking. When I open the door, no ones there but I hear running. I keep one of the doors open and that's when I see the security officer walking down the hall and hear a girls voice. I've subbed for this girl many times and she asks to leave class a lot but I let her because I know kids at that age need to move around otherwise they get anxious or excited which makes it harder to manage them. I'm also very lenient with her on block days (when we have two hour classes). I have noticed her hanging around the hallway near the class with other students. I didn't think much of it but after what she did I realized she wasn't really going to the nurse or bathroom or the water fountain. So I grabbed a referral from the teachers desk and wrote her up. After turning it in to the office, I was told they gave her 2 days ISS. A few days later, when I subbed again for a different teacher, after the dismissal bell, I saw her walk by me and she was talking about me out loud but I didn't acknowledge her because I was in a rush to my second job and didn't have time to lecture her. I really do want to talk to her but I'm not sure how to approach her. I wanted to do the firm, scolding talk but knowing this girl, I don't want to enrage her or even maker her cry. I don't want to parent her, that's her Moms job (even though her mom is the type of parent that wants to be her kids dis friend instead of being a parent, the girl comes to school with her lips pierced and the school called her mother and she yelled not at the student at the assistant principal). I want to know what's the best way to approach this girl.
