I am a 2nd year teacher with a year 4 class. Last year my class were practically perfect! Of course I look back with rose tinted glasses as they were my first class. They were lovely though and so well behaved. This is long and rambling but I need some advice please. This year it is a whole different story. I have lots of children that are simply nasty to some of the others. I have one boy who is rambunctious and the other children pick on him for this. He struggles to control his behaviour and does do some things to hurt the other children. The other children then over react and really hurt him. My problem is, as much as I bang on about being nice to each other, making sure everyone is included in games and accepting some of the differences between themselves they just cannot do it. I had a few parents raise some names yesterday and some issues that have not been brought to my attention. I have also just found out that the children are not talking to me when problems happen. It is very upsetting to hear some of the things that are happening. My HT has spoken to several boys and the whole class as I am now at my wits end and really have no idea what to do about it. One boy in particular is 'leader of the pack' and most of the boys look up to him even though he is the one causing a lot of the nastiness. I have had to do a lot of work with this boy anyway as he was refusing to work for the majority of last term. Although he is working now he still has a real attitude problem and a self inflated ego. Again the HT has said that peer pressure would be the way to stop this boys behaviour but the others think he is cool and don't see it as a problem or are too scared in case they end up with no friends. We do SEAL but I don't think that it covers the issues we are having and I want to introduce some circle time. I am not very experienced with circle time though and would like some suggestions on how to get across the importance of being nice to one another. I really am upset by some of the things that I have heard as some of the children in my that this is affecting are really lovely but feel worried about clothes they wear or who they play with in case the 'leader' or his friends say something. Any help would be appreciated please.
