I watched him in class again last Monday. It looks to me like his biggest problem is the lower muscle strength/endurance that he deals with. It makes it impossible for him to keep up with the other kids. At the beginning of the class the teacher assigns a writing exercise, one paragraph minimum. She allows about ten minutes to finish before she starts going over grammar lessons with about two written pages of notes that he is supposed to copy off the board. He usually gets a couple of sentences of his writing assignment down before she starts grammar lessons and then has to try to finish his in-class writing assignment while he is also listening to the teacher. I watched him try to copy the grammar notes fast enough to get it down before she erased the board and then write a few words on his writing assignment and even with his multitasking ability his mild muscle weakness and his hand cramping slows him down. If he switches to his left hand to write for a few minutes, his writing is still legible but he loses even more speed.
When I saw there was no way he could do all of the writing before the teacher erased the board, I got some paper from him and told him I would write the notes off the board while he finished his writing assignment that had to be turned in by the end of the class while the teacher finished the grammar lesson. It is a good thing that he is very good with grammar to begin with because I don't see how he could finish his writing and really get any of the grammar lesson.
At the end of the class the teacher assigns another writing assignment to be done at home and turned in the next Monday. He can type it so there is no problem. If he is allowed to type he can produce A+ work and he feels really good about this. For the first time he is getting other opinions of his writing instead of just his parents. He says he likes writing and would like to write a book some day.
