The First Plane of DevelopmentDr. Montessori referred to the first stage in human development (birth to age six) as the time of the absorbent mind.
She understood these first six years of life to be the most fundamental in the development of human beings. This stage of a child's intellectual and emotional development is different from any other time of life; children are in essence creating the people they will become. At this stage children are sensory explorers, building their intellects by absorbing every aspect of their environment, culture, and language.
