We too are finding the same thing in our Montessori school as belle mentioned. Our DD is currently in a 1st-3rd level class, as a supplement to a 3rd grade placement in a homeschooling virtual academy. We love the fact that she gets to be in a classroom setting with grade level peers, however, we find that she is spending lots of time just going through the step by step progression of subjects, even though she already knows the material and concepts. We do not stress too much about it since she only attends 2 days a week, and she is not complaining about it. However, it has made it clear to us that a full time placement in the Montessori class would not be a good fit for her. She just moves through information way too fast for their comfort, and already knows things (granted, she hasn't been formally taught many of the concepts) and is ready to keep moving and building on them.
The Montessori teacher we have is very sweet and caring and really wants the best for our DD, I just think her Montessori training is so engrained in her that she cannot fathom moving DD along quicker or skipping steps.
