I am an NQT who has just taken over a Year 3 class in January from their teacher who went on maternity leave. There are 26 children in the class, more boys than girls. I have 4 or 5 boys within the class who are quite a handful behaviour wise. They think nothing of talking over you when you are talking, getting up out of their seats, answering back and generally messing about/wasting time. Once one of them starts playing up this usually sets the rest off. I've tried a traffic light system, putting their names on the board, taking 1/2/3 minutes of playtime off them, giving them a stern few words or a pointed look. I have also implemented 5 golden rules to refer to and bring children back to when they do not follow. My question is that although I have seen slight improvements since starting last week (the mornings are always better than the afternoons), I am still having problems with this group of boys, should I persevere with my strategies or try something different? I know getting the behaviour under control will not happen over night, but I am conscious that unless I show these boys that I can manage them, they will think they can do whatever they like.
