Hi everyone, I'm currently tutoring a Y3 boy who has autism and I'm looking for some advice. He is very bright, but is really struggling in maths due to a lack of understanding of the basics - the number system and the concepts of the four operations. He is verbal, yet much of his speech is echolalic and doesn't seem to be relevant to the task he is completing at the time (to an observer, I mean - to him it is relevant). He will answer straightforward, closed questions, yet if he doesn't know the answer it is difficult to figure out why, or what part of the task he is struggling with. His memory is excellent and he knows some of his times tables but I don't think he understands the concept of multiplication, he has just learned them by rote. I had a bit of a breakthrough with addition not long ago and he is now able to carry out simple addition using counters or toy animals and he understands the process, however, I am really struggling to help him understand subtraction. Part of the problem is he is really uncomfortable with the idea of 'taking things away'. For example, if we set out e.g. 6 counters and 'take away 3', he often gets quite upset. With single digit numbers, we have able to 'count on' to find the difference using our fingers and he was able to do this. I'm a bit worried about it though because I don't think it is helping his understanding of subtraction at all, in fact I think counting on to find the difference felt exactly like 'adding' to him. I know this is a really individual case, I just wondered if there was anyone out there with any other ideas of methods of teaching the concept of subtraction. Also, if anyone has any experience working with autistic children that they would like to share, that would be great too. I've cross posted this to maths and SEN. Thanks in advance.
