While Structure and Order seem counter-intuitive to the aforementioned freedom, nothing could be further from the truth. Structure and Order in the Montessori classroom accurately reflect the sense of structure and order in the universe. By using the Montessori classroom environment as a microcosm of the universe, the child begins to internalize the order surrounding him, thus making sense of the world in which he lives.
Montessori stated that there is a sensitive period for order which occurs between the ages of one and three years of age. This is when the child begins to draw conclusions of the world around him. If there is not order to his environment, the child’s sense of reason may be off since he will not be able to validate his findings.
This is not to say that routines or classroom set-up or ways of doing things can't change. However, it does mean that change should be carefully considered. Is this change for the good of the children? If so, it should be done carefully and its after-effects should be observed to ensure that it is of benefit to the children.
