Montessori places a great emphasis on using the right materials for the job. Really, have you ever seen a Casa teacher going through a giant box of trays for the perfect one. This attention to detail is passed on to children. If the teacher is not careful, the children can grow up to be unable to be flexible. That is one of the reason I love creativity in physics. It helps kids problem solve.
