Montessori emphasizes learning through all five senses, not just through listening, watching, or reading. Children in Montessori classes learn at their own, individual pace and according to their own choice of activities from hundreds of possibilities. Learning is an exciting process of discovery, leading to concentration, motivation, self-discipline, and a love of learning. Montessori classes place children in three-year age groups (3-6, 6-9, 9-12, and so on), forming communities in which the older children spontaneously share their knowledge with the younger ones. Montessori represents an entirely different approach to education.
