The most distinct difference between Montessori and other methods is in the nature of the materials:
materials are not didactic (teaching tools), but self-teaching tools.
These materials are not for the teacher to
teach, but for the child to discover and learn on his own.
The adult presents a concept and a correct use of the materials; the children explore within the confines of respect, responsibility and expectations (ie with elementary work contracts).
The children teach
themselves – these materials are developmental
materials. They fit for a stage in the development of life, as the child is constructing himself from the environment around him.
