I feel out of my depth at the moment. Started teaching a year 3 class and one child has aspergers. He gets easily frustrated and calls out all the time. When I give him work he says he has finished 5 minutes later, the quality is quite poor and as it took it such a short amount of time I am sure its not his best effort. I gave him some work yesterday and he said 'but that'll take forever' then started banging his head on the table. When colouring in he just uses one colour and scribbles. I asked him to look closely at all the different colours in the original piece of work he was looking at and he screamed at me saying he was trying. Someone please help how I can get the best out of this boy without him getting angry.
