School Notes
- School Mascot: None Available
- With constant interaction and problem solving child to child each child is challenged according to his ability. Curriculum is integrated. No subject is taught in isolation. As soon as a child understands a material, he may work on it independently. When he masters a material, he receives a new lesson. The Montessori method provides the opportunity for the child to develop independence, confidence, creativity, self-motivation, responsibility and academic competency. Montessori directives complement the needs of all children, while affording the freedom necessary to preserve each child's uniqueness. Our school is located in a new building in North Potomac. It has been designed specifically for Montessori education. Many months of research has been done in determining the architectural details which provide comfortable, home-like classrooms and an environment conducive to the education of young children.
