The third year, the kindergarten year, is an important year in the Montessori three year cycle. It is a time when many of the earlier lessons come together and become a permanent part of the young child’s understanding. This is the year they become leaders in their classroom. They have an opportunity to teach the younger children lessons that they have learned. When a child can teach a lesson they have mastered, it benefits both the tutor and the tutoree. It takes their mastery to a different, more concrete level.
