The size of the school and each grade make the environment like a family. Student know each other and interact with various teachers and even the principal at a personal level.
The addition of "houses" creates a great sense of team spirit and accountability for my child. It also allows the students to interact with kids outside of his grade. My son has already made a number of good friends within a short period of time. One of the motivators to move my son from his previous Montessori school to Sunnybrook is the class size. I wanted my son to experience a more "real world" class experience, without having to be in a very large class where his needs could be forgotten. With only fifteen kids in his class, he has a good balance in learning how to work with other kids, "sharing" the space, and being able to learn from others. The overall size of the entire school is not too big or small, and creates a great sense of community.
The student body at SBS is small, and this is one of the major factors that initially drew me to the school. With grades from JK to grade 6 represented, and a maximum of 20 students in grades one through six (16 in both JK and SK), the sense of community is wonderful. It is such a welcoming and warm environment, which is especially nice for smaller children. Students at the school are respectful and polite. Older children get to know the younger kids through programs such as learning buddies, which have benefits to both sides. Children often make friends with students in other grades. They get to know other students through house games and activities. I can't imagine my daughter having a better school environment - it is simply wonderful.
