It is a wonderful environment that is able to be designed and adapted to meet the needs of the development mind and body of a young child. Through the use of materials and activities that stimulate the natural curiosity of children, they can build concentration and work towards being independent. Dr. Montessori found that children learn by doing that they became self-disciplined through concentration on purposeful activity. Different ages and ability level allow for appropriate modeling of behavior and emulating of skill shown by the older children. Over the ideal three year period, this helps to perfect those skill and knowledge and prepares the children for the future.
