I've taught the same lovely age group for three years but in the last three months, one six year old boy is causing chaos. I think in the first instance I noticed that it would take him an extraordinary length of time to write on the IWB - usually in phonics - and it would be writing one letter, then rubbing it out so that it looked nicer, but I felt the whole performance was because he wanted to be doing something. His favourite thing in the world seems to be tidying - he seems to think that he will get constant praise for reorganising resources I've laid out ready for the next lesson when in reality I do not want him touching them, I want him to follow instructions. If students arrive at 8:40 I usually have early work ready but he hates to start something and then stop for example to sit on the carpet for the 9:00 register. When I choose other students to talk (I am routinely able to ask almost the whole class to take a turn to speak/demonstrate a particular skill) he shouts out that "it's not fair" and he ruins their turn by calling out the answer to irritate the chosen child. If he is taken to an intervention (e.g. withdrawn from class for extra maths) he monopolises the situation with the Teaching Assistant - demanding that he carries the tray of resourses, that he hands out the pens, that he tell the other children how to do the activity. He came roaring and shouting into the classroom (late 9:10am) the other day shouting that he wanted to chose the child of the day - technically it was his turn but due to horrendous behaviour he had not been able, then due to being late we had chosen for him. The Teaching Assistant was so scared of him carrying on with this temper tantrum she was arguing with me across the class that we need to let him change the child of the day - causing another child to burst into tears. I have tried using sticker charts - when he moves off his carpet space/seat, or begins shouting out over the teaching input because another child has a chance to speak (His latest thing is to shout that whatever we are learning about doesn't exist) but he gets hysterical about not getting a smiley face sticker - I remind him what behaviour I want to see and he can get a sticker but he shouts that "I am doing the right thing!" If I use parallel praise to say another student is sitting nicely or listening well he calls out "and me!" This sets one or two other children off giggling - one or two have called him a baby - and he starts yelling "Don't look at me! Don't laugh at me!" If I tell him he is missing break time due to disrupting learning he tries physically to get out the door and cries for 25 minutes. I know this is ridiculous in that with this age group usually the offer of a dojo point or the mere praise of another student has them all displaying the right behaviour to enable learning to flow smoothly - I feel that he has brought a bullying campaign of terror into my classroom - and he is only six! What should I do?
