For a great introduction to the importance of the kindergarten year in a Montessori classroom, check out the video below: "A Time to Blossom - Montessori for the Kindergarten Year" by the Montessori Foundation. It provides a wonderful overview of how Montessori kindergarten acts as a capstone for Primary students - enabling them to reach their full potential academically in the classroom and empowering them to act as leaders and mentors for the younger children.
