About the School
- Children's World Montessori strive to make our students world citizens, fostering global awareness, kindness, and compassion.
- We provide an open, caring environment, helping students resolve conflicts calmly and peacefully, while giving them ample opportunities to grow and develop as individuals.
- Montessori found that this multi-age setting provides children the opportunity to learn from each other and because of each other.
- Younger children learn from older students, and older children reinforce their own learning as they share with the younger children.
