How they teach

Montessori and nature and outdoor

“Our program is founded on the AMI Montessori philosophy, supplemented with exposure to major world languages.”In their words, July 2026.centennialmontessori.org

“We believe the outdoors is an extension of the classroom. Our program provides ample opportunity for children to connect with nature, whether through gardening, observing insects, or simply enjoying unstructured play in the fresh air.”In their words, July 2026.centennialmontessori.org

One of 43 Bay Area providers that describe a Montessori approach, out of 164 that describe any approach at all.
