The Montessori environment is based on a multiage classroom. The preschool environment has children from 2 /12 to 6 years of age. Having a mixed age group allows the younger children a grade series of role models and lets the older children reinforce their own knowledge by helping younger peers.
The environment is prepared by the teacher to be inviting and spark the child’s curiosity about the world around him. This is why the materials are graded in such a way that it allows the child to grow from one level of complexity to another in a natural progression.
