We tried Montessori for Pre-K and it didn't work for us. The first school called me in the office after a week and told us that our DS had basically completed everything they had and they weren't sure what to do with him. This was a program that only went through 2nd grade. The second place we tried went through 6th so we knew they wouldn't run out of work. The problem we ran into there was the complete rigidity of the school. They wouldn't let my son move forward without taking every single calculated step in each exercise. DS doesn't work like that. You give him a basic concept and he gets it, he's able to leap forward without doing the incrementals. It drove him crazy!
If you can find a school that is Montessori based but allows some flexibility, it could work. We always thought that if we could just find the right one, he'd love it. But where we live the choices are limited.
You might be better off to find social outlets such as homeschool co-ops and clubs like boy scouts.
Best of Luck!
