International Montessori School

International Montessori School is developed around the turn of the century by Maria Montessori, Italy's first female physician, the montessori method consists of a specialized teaching style and expertly designed materials that combine to unlock each child's natural motivation to learn.
Further, as montessori does not segregate children by age, older children share their skills and knowledge with younger ones.
This not only acts as an important motivator, as the younger ones emulate their more advanced peers, it also serves to develop crucial social skills as well.
