My kids fall under the umbrella of stealth dyslexia. It's dyslexia on super stealth, though - reading has never been a problem. As Kathleen's mum describes, not everything needs to be modified, just those things that the child needs. My kids go to public school, but if I were starting this as a homeschooler, I would start armed with data: get the testing done and identify the actual weaknesses and accommodate them. My kids need OG to learn to write and spell, but not to read. My kids need accommodation for transferring information - this actually would suggest against learning math on a computer in which problems need to be worked on paper as the information transfer introduces errors. Traditional paper and pencil instruction is 10000 more effective for my kids.
My kids also need time to let the asynchronous parts of their development just plain develop. If I could have a do over, I think I would introduce next to nothing in the way of composition, be it writing or dictation, until much older. I would introduce OG and writing mechanics relatively late and before tackling writing fluency (journals are torture devices in my house).
The upshot: Do some testing to see what *your* child needs. Take advantage of your homeschooling flexibility to look critically at how your educational approach is proceeding and accept that you might have to experiment and adapt as your child grows.
