LOL my DD used to do that dot or single line thing for coloring, I forgot about that!
Homeschooling books that are nice are The Ultimate Book of Homeschooling Ideas and Creative Home Schooling (Resource Guide for Smart Families).
For "output" ideas after learning units or whatever interest is going, there are things you can mix up with writing (for example book reports) like collages, dioramas, building things. You can just keep working on the handwriting a little bit every day but not be stressed. He can do combo things like creating a notebook or dictionary of terms for an interest with a definition and drawing.
My DD loved a bag of mixed dried beans and an empty egg carton, she got so much out of it. And making a marble run type thing from paper towel and toilet paper rolls. Can you have a garden, you can get so much science and things out of that. We cooked and baked alot and she learned alot of math from that. We spent alot of time outside and observed - always have lived in 4 seasons.
Technology can actually be a saving grace for some kids with organizational and writing challenges. My DD has gone into a very writing intensive environment and it's a challenge but as she moves up technology is taking over and it's something you can even shop around for in schools if you get to that point.
Everything in moderation - I've started using the word "balance" every day with my DD. I say if there is one thing she can remember that I taught her it's that - balance. Balance being outside with screen time, sleep with being active, being in the company of actual humans with being alone - etc.
I too like her to learn to do things "for real" before short cuts and understand how people used to do things - she's always loved inventions and how people have made things better, faster, stronger etc.
I think it sounds like a fun opportunity and if you mix up all the ideas here it will be really enriching.
