We now know that when a baby is born, genetics determines the broad parameters for brain development. The only brain cells (neurons) that are connected at birth, however, are those that control survival functions such as heartbeat and breathing; the rest of the connections (synapses) begin after birth. Synapses that are reinforced by repeated experience become a permanent part of the brain and will shape thoughts, behaviors, abilities, and emotions throughout life. By age two, the number of synapses reaches adult levels and children's brains are as active as those of adults. By age three, the age students start at Montessori, the brains of children have two times as many synapses as adults and are twice as active as adults. This level is maintained for the first decade of life. Just as synapses that are reinforced will connect for life, a synapse that is not reinforced will wither away in a process called pruning, making certain abilities more difficult to regain later in life.

Montessori classes are comprised of children representing a three-year age range. Classes include a well-balanced division of ages and genders, as well as an appropriate number of children to ensure strong social development. Children learn from one another by observation, and are presented with the opportunity to play a number of roles: the youngest, the middle, and the oldest – each different, complex, and equally important!

Classes are scheduled five days per week with prolonged uninterrupted work periods provided each day – morning and afternoon. An extended day (afternoon period in addition to mornings) is provided five days per week for older children in the primary class. Children thrive on routines, patterns, repetition, and a sensory-rich environment. The consistency and stability of five consecutive days of Montessori instruction creates less angst for a child, and provides a solid foundation for success.
