I have a Yr11 RE class once a week, they are a fairly large, all female class and I'm teaching a subject that is not my specialty (several teachers in this school are given extra subjects, due to staffing a timetabling. I also teach Yr8 History, which is far better). I feel like there is a bit of a 'pack mentality' with these girls. I'm female as well, and they have very little respect for me and the subject and don't take it very seriously. We got off to a terrible start, and I made several phonecalls home, which narked them off and they seemed to play up even more. In lesson, they were almost trying to 'out do' each other with their behaviour. The head of behaviour know this is a 'hotspot' class and has done his best to help (speaking to the girls individually, giving me tips on building relationships etc.) I felt like I was getting somewhere with the class, but then this week they decided to start playing games. This included, one girl yelling "sniper on the roof!" while the class hid under the tables. Another was to start doing 'We Will Rock You' on the tables, and then humming until everyone joined in. All very mature for Yr11s! I ignored the behaviour as I felt they were doing it for the reaction, I also couldn't pin point the ringleader(s). I had quiet words with some girls, but did not want to stop the class - partly because, I have trouble getting them quiet anyway and I did not want them to think their behaviour was getting to me. My plan is to come down on this next lesson if it continues. I was hoping it wouldn't, until one of the girls told me in her normal lesson with me that "everyone takes the p*** out of me, and some people torture me". I laughed at the suggestion and shrugged my shoulders. I tried to create the impression that I didn't care and made reference to the games in the RE lesson, but if I'm honest I was a little bit gutted inside and I'm worried that I was a little too slack in my response to her and the class's behaviour. I can let most things wash over me, and tbh I have a pretty good relationship with a lot of kids that I teach. But I don't like the feeling that some classes 'plan' to misbehave and make my life difficult. Does anyone have any advice for dealing with these games in lesson? Especially if I can't pick out who is starting it. Am I overreacting?
