Our Montessori classrooms are designed for mixed ages, encompassing a full three-year age range once children leave toddlerhood and enter Primary. The wide range of abilities and personalities in a mixed-age classroom creates natural opportunities for children to learn to appreciate individual differences in people, and affords a variety of social opportunities. In the mixed-age classroom, younger children look up to, and are inspired by older children, while older children become leaders, mentors, helpers, and the role models for them.
