Why do Montessori classrooms have mixed age groups in one class?
Children learn from one another. This can be seen in family and play situations where children are free to observe and interact in a variety of activities. Young children learn higher-level cognitive and social skills not only though mental development, but also by observing others as models. Multi-age grouping helps children develop a sense of community and supports social development. Older children act as role models and (sometimes) teachers of younger children. This aids in the development of personality, collaboration, and cooperation. Montessori classrooms have used mixed age groupings for over 100 years. At GMS, the age groupings are as follows: Toddlers – 18 mos. to 3 years; Primary – 3 to 6 years; Lower Elementary (Lower El) – 6 to 9 years; Upper Elementary (Upper El) – 9 to 12 years; Middle School – 13 to 14 years (7th and 8th grades).
