The Montessori Lower Elementary Program is designed to help each child function at the upper limits of his or her potential through a wide spectrum of educational experiences. Individualized instruction prevents the child from having to wait on classmates to catch up; all students work on personalized contracts and schedules. At any given time, some are exploring language materials, some are doing math, and some are performing science experiments, while all are quietly and excitedly pursuing excellence. Since the materials are always available to the children, they may return time and again for hands-on experience until the lesson is mastered. The Montessori materials offer open-ended exploration and avenues for self-expression.
