I did Montessori though 4th grade. Moving to public school in 5th grade was a shock because, while I had been doing algebra self-directed, I never memorized my multiplication tables. I really resented being forced to memorize lists that I could just look up in a table (though I would freely memorize other things). So when I got into 5th grade, I failed all my math tests. I decided that didn't feel good, so I memorized those really fast. :) In retrospect, I am really glad I moved a bit earlier, because I think going straight from Montessori to 7th grade (junior high there) would have been a big jump. Moving over while still in elementary school eased that. But that was me and my situation.
