The embryonic development of each of its parts, which is at first carried on from birth till three, must in the end become integrated, when it will be so organized that all of these parts act together in the service of the individual. This is what is happening during the next period, from 3 to 6, when the hand is at work and the mind is guiding it.
(Montessori, Absorbent Mind. Pg. 184-185)
My fascination with the 3 to 6 y age group continues to grow as I delve more deeply into it. Dr. Maria Montessori's integrated approach is outstanding.
