Here's some advice from someone who has only homeschooled in fantasy.
Remember that for many many years, homeschool was the norm, and no one tried to figure out in advance who would thrive with the system.
Seems like the first 'lesson' for homeschool would be to set up a 'charter' for your family school. Be the scribe and the interviewer and find out exactly what your son would think is fair for a homeschool.
Would he like to do each subject each day, or have a Math Day, English Day, etc.
How many days would he like to spend 'at home' and how many days would school be 'on the go?'
Do you know other homeschoolers that he would like to learn with?
How would your son know if he was meeting or exceeding reasonable expectations?
What about TV or computer during the day?
How many playdates during afterschool hours per week would be ideal?
How much of a free period for reading or educational TV would be allowed during the day?
What about physical activity?
What about household chores? (Seems to me that if you are adding school to your responsibilities, that a DC should be willing to take some of the daily househould responsibilities off your plate. Plus cooking, meal planning, tidying up can all be great learning experiences.)
I would ask your son about the parts of school that aren't fun, and how he would propose to handle 'doing the essential, but unfun parts' of school at home.
My hunch is that DS will have lots and lots of ideas about how 'he would run the school.' My guess is that even if you would modify half of his rules, that you'd love the other half.
Enjoy,
