Actually, I went to a Montessori school from kindergarten through 3rd grade. https://news.ycombinator.com/item?id=4459226

Summary: There were 60+ kids and only two teachers. The kids were allowed to do whatever they wanted all day. About the only thing I learned is how to forge the signature of my assistant teacher. And some kid hit me with a metal shovel and wasn't given more than a stern talking to about why hitting people with shovels is a bad thing.

I may have just gotten unlucky in attending a particularly bad Montessori school, however.
