An online search is a good start. Another way is to go where homeschoolers go--look for homeschool gym classes offered at local gyms or art classes for 10yos in the middle of the day.

As for which rules to follow, it's usually the school district you are in. Just your district's rules apply to you, I think. (But I am SOOOOOO not a legal expert on this!) An Internet search should help you here, too.
