The Montessori philosophy proposes that children learn best in age groupings that span a few years. As in a family, the role-modeling of the older child inspires the younger child in the next step of personal development and skill refinement. Both children have the benefit of working and learning from each other as well as from adults.
“There is a great sense of community within the Montessori classroom, where children of differing ages work together in an atmosphere of cooperation rather than competitiveness. There is respect for the environment and for the individuals within it, which comes through experience of freedom within the community." - Maria Montessori
