Montessori  is an educational approach that values the human spirit and the development of the whole child- physical, social, emotional, cognitive. Dr. Maria Montessori observed that children under six absorb the world around them limitlessly and effortlessly and that is called ‘sentisive periods’ or ‘windows of opportunity’. During this time children build all the foundations for later life and Montessori teachers provide appropriate lessons and materials to help them develop their full human potential. Everything in the classroom is designed to develop children’s cognitive powers through direct experience: seeing, hearing, tasting, smelling, touching, and movement and allow children to become independent. The materials are child sized and the equipment is aesthetically pleasing and is meticulously cared for which encourages the children to take care of it too. Younger children learn from watching older children and older ones reinforce their learning by teaching concepts they have already mastered. Multiage grouping is an essential part of Montessori approach. The curriculum consist of four main areas. Practical life gives the children the opportunity to refine the skills of everyday life and helps to develop concentration, co-ordination of mind and body. The sensorial materials help the children to develop and refine their senses to learn and encourage to order and classify the physical properties of the world they live in. The materials for mathematics is perfect tool to help the children to understand mathematical concepts because they are presented using concrete materials. Learning language is a natural pregression. Children learn how to write and read from the minute they come into the class through a series of activities that gradually build all the skills they need.
