LA Question/Dysgraphia?

I’d like to use some SCM items this year and I have a language arts question. My son will be 11 later this month and has always had trouble with the actual process of handwriting. He always fusses and groans and it is torture to watch him try to write. He has been slowly learning cursive the last couple years and he does ok with it. (He still groans.) But when he prints, he writes in all capitals. He says it’s easier. His writing is very large with not much spacing. I know boys are slower to mature, especially fine motor skills. I have two older boys and a younger 8 year old daughter. She loves to write and her printing is very neat.

First of all, I wonder if he has dysgraphia? My ds16 is dyslexic so I wonder how that could factor in. Although ds11 is probably my best reader and speller. He doesn’t mind doing compositions or writing but in those cases he has typed his work. I’m wondering also how to do SW and ULW with him. Do students actually hand write the entire dictation selection in Book 2? Some of those are very long! I used some of Book 1 with him last year, starting at the beginning, but I had him use a separate sheet of paper if it was longer and had him write two spaces high with a space in the middle. We didn’t keep up with it, unfortunately. I always wonder if I did him a disservice in not keeping up with the discipline of writing, but the “all capitals writing” is throwing me off.

Thanks for any advice.
