I've recently taken over a challenging Year 2 class, and while most of the class are lovely, I have four boys who argue constantly. Two of them deliberately wind the other two up, and then they shout and generally cause a lot of fuss. When spoken to they have tantrums like toddlers! One of them has had lots of input and is improving, but gets off track because the others' behaviour makes him angry. This child has a reward system which is working well. What else can I try? The other three boys are generally angry and reluctant to do anything in class. I know they like cars and Mario Kart, but struggling to think of how to use this to my advantage. I don't want a reward system for these boys because they already gloat about anything "special" they get to the rest of the class and I don't want them to be made any more different from the others.
