It is established that early childhood years lay the foundation to a person's development. Seventy percent of a child's brain is developed in the pre-natal stage. The early childhood years (0 to 6 years) are life defining, and it is here that we discover our strengths and abilities. Research has proven that at this age brain activity is at its peak and the stimuli a child experiences here leave impressions for a lifetime. Hence, everything a child learns after 5 years of age is a reinforcement of what she/he has already learnt at pre-school. Pre-school become the single most important avenue where the child can gain a sense of self, explore, play with their peers, and build confidence. Children in preschool learn how to socialize - get along with other children, to share, good behaviour-management skills, how to compromise, be respectful of others and problem-solve. Children who attend Montessori preschools enter formal schools with better reading skills, richer vocabularies, and stronger basic math skills. This facilitates an easy transition from preschools to formal schools.
