When I taught (high school and middle school), I tried to do much the same thing. Schooling outside was pretty much impossible (ever spent a winter in Milwaukee), but we did what we could within the four walls. I tried to support each student's individuality and often let them pick the curriculum. Some of the things we did came across as silly to many of the parents. But the kids generally loved it, The biggest problem for the parents was that my way of teaching did not enhance the possibility of going to college. (I believe that all the students who wanted higher education eventually got it.) I did the same thing with my own 6 children. Though I am highly educated, not one of my children chose my path. But all of them are emotionally mature adults with many passionate interests. Those that need math in their adults lives have become good at it; the others have not. By my standards,, they have done well.
