YOGA
Montessori argued that healthy children are naturally drawn to a sense of the spiritual: reflectiveness, good will, a love of work, and so on. This is the root of the "normalized child"-the positive model of health and intelligence that all Montessorians are called to facilitate.
Introducing yoga to the Montessori classroom is one way we promote the normalized child.

Small children are naturally oriented toward process rather than performance. It's possible to train small children for performance. But it forces them into directions that are usually difficult and often counterproductive. As Piaget pointed out, small children are naturally egocentric; they have difficulty imagining the points of view of others.
One of the key insights in Montessori is to stimulate human development to provide children with opportunities for satisfying encounters with satisfying, engaging work-work which attracts children through "points of interest" rooted in critical developmental issues. These are issues (such as the seven Piagetian conservation problems) that the child can't quite understand but that intrigue and puzzle and draw the child in.
Yoga is part of our normal work day and fully integrated into the environment.
