This is a bit of an embarrassing issue really. I would like to know how I should have dealt with it because I'm just not sure how to react should it happen again. I have a difficult year 8 class, mostly due to a small group of girls, though many pupils in the class are difficult (five of the class are lovely). When I started in September I went in too hard, giving lots of sanctions, phoning home as soon as the same pupil had had three detentions from me etc. which damaged my relationship with the group. On Monday last week, I took my jacket off in class. The group of girls then started to make comments about me having BO etc. I made it clear that they were being rude and they needed to stop, which minimized it but did not entirely eradicate the issue. The next lesson was Wednesday, when this same group turned up to class with pegs on their noses. I told them they needed to put them away and if I saw another peg they would get warnings. I followed through on this, and they did put them away, though clearly very pleased with themselves. I didn't want to make too much of it because I didn't want to show I was bothered by this but at the same time I obviously had to sanction them. It seemed too vague to send them out on, but I should I have sent them out to another class? I told my mentor (I'm an NQT) who agreed that it was the way to go, but is this right? Is there anything else I should have done? What they are doing is totally puerile but it feels like they are in control because I'm not sure how I can deal with this decisively. They're the sort of class that just decide to ignore everything I say and are not bothered about detentions (and I have spent whole frees adding detentions and following up). Phone calls home do not have much of an impact either. I've only got two weeks left of this class - and this school - but it's very demoralising. Thanks.
