I currently teach year 4, top set Literacy. At the start of this year I had a lad who was working at a 3a but would write no more than about a third of a page. Through the use of a sand timer we got this up to about 3 quarters of a page in a lesson (compared to 2 sides from some others). Finally I was able to give him the level 4 he deserved (4b evidence but gave him 4c due to quantity). Unfortunately, over the last 2 terms the quantity has dipped again. I can't give him the level I know he is, due to a lack of evidence. He can't tell me what the problem is and is often quite disappointed that he hasn't completed work. There are suggestions of slight Aspergers as well as possible ADD; Mum won't have any of it though. Does anyone have any tricks I can use to help this child start writing more again?
