I'm sorry that Charlie's having a hard time-I hope things are better now that you've spoken to his teacher. Does his class have any extra support or is it just the one teacher? I only ask because I'm currently teaching a child with Aspergers Syndrome and I get a classroom assistant for five lessons out of every eight-and I can guarantee that this little boy's productivity goes up 110% when there is someone there to help him with his work on a more one-to-one basis, and his frustration goes down by the same amount. Classroom assistants can be really useful as they can build up a relationship with children that class teachers don't have enough time to do one-to-one, and having someone there to guide definitely helps me, and the little boy, especially as there are other children in the class with literacy issues and other dignosed conditions (don't ask me how, but it's the class with vertually ALL the dyselxic children in this year-seems a little unfair on them, really, as they need extra support at times).
Of course, this is probably irrelevant if Charlie's in a class of less than 30 and there's no clasroom support-if that's the case, then the teacher shouldn't have any problems building the relationship his/herself.
I think it's really useful that you spoke to them, though, as the most vital thing is to have as much information as possible about a student-that way, it's so much easier to spot trigger points and possible issues in the classroom. If I had the time, I'd love to sit down with all of the parents of the children I teach for a proper chat, and not just the 5 minutes once a year on parents' evening. The information is invaluable! Did Charlie's old school pass on his records to his new one? Sometimes teachers don't know where to start if that information isn't received before the start of term-which makes your approach of talking to the school even more invaluble.
Anyway, I've droned on long enough-I hope you're both OK and things start to improve for Charlie :)
Best wishes
