Austin - I am worried that my son will quickly exhaust all the activities they have to offer in his classroom. On the day I visited, even the materials the 6-year-olds were doing were right at his current level. In this moment,though, he is happy. I'll always have my eyes and ears open and always be re-evaluating. I've never been a kool-aid drinker.

Grinity - Sorry, I should clarify! I don't want to encourage him to be a class clown, or have any disruptive behavior. What I meant was that he is a very creative, imaginative, and funny kid -- all positive qualities that I want him to embrace in himself, not push away. Class clown was a really poor word choice on my part because that implies disruptive and negative behavior, which of course we don't want to encourage. That is the kind of behavior that will come out if he gets bored or frustrated.
Thanks for this great discussion. Montessori is so mysterious to those of us that grew up with traditional schools... this has been enlightening!
