I will be putting my son in two classes next year at the high school and we will be homeschooling everything else. Our state (WA) allows homeschoolers to access as much or as little in the public schools as we choose, but when he was elementary age, I felt that putting him into a classroom for just art and PE (or whatever) and then removing him the rest of the time would be bad from a social standpoint, and since my main reason for having him in a classroom would be for the social piece, I never did that.
