School Notes
- 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.
