The IB curriculum was a decision making factor for us. The way it is administered at Sunnybrook is very structured. You see how students learn to think and to inquire. These are the foundational tools they need to possess as they grow and move to higher grades.
My son is keenly interested in what he is learning in the classroom, and that translates into the questions and discussions we have at home. His teacher has been very supportive and encouraging. In my son's words, his teacher is very "nice" and "funny", and he is very comfortable to approach him with any questions or concerns he may have. There was one incident where my son was acting out a bit in class. The teacher was quick to correct the behaviour, and notify myself in order that I can further enforce the teachings. He is also very fair in his distribution of homework. He assigns a reasonable amount, and also breaks down the work load to help encourage students to effectively time manage and prioritize.
This school is spectacular and the teachers are the main reason for this. As a teacher myself, I know what above and beyond teaching looks like. SBS is that and more. The warmth and energy these teachers bring to the classroom every day is incredible. The lengths they go to in order to engage their students amazes me. The interdisciplinary approach and the IB program are wonderful. My daughter comes home linking information from science, to her library classes, to a field trip that the class has taken. SBS demonstrates what teaching should be but often isn't. I was hesitant as to how much of a difference I would see (having my daughter do JK at a public school, moving her to private for SK). It is night and day. We have frequent positive communication from her teachers, and even receive pictures of special moments (the first tooth coming out). My daughter is being taught challenging material, but the support the teachers provide allows her to rise to those challenges.
