My wife is a Montessori teacher of 1-3rd. From what she's told me, students transitioning to Montessori should do it as early as possible. Apparently older students in the "established" system have a hard time achieving the mental switch in thinking. What I've enjoyed is watching how lessons are very "touch" oriented. Seems every lesson has a visual or touch oriented wood tool. The students are dividing 6 digit numbers in 2nd/3rd (!).
