The Beacon math department’s mission is to help develop young people who see mathematics as a useful tool for exploration and understanding. We create a student-centered environment in which student groups pose strong questions, assess alternatives, and think critically. Across our curriculum, we employ a mixture of skill development, collaborative conversation, and applied work in context to develop our students’ reasoning abilities. Our students demonstrate their growth using a variety of both routine and non-routine tasks that culminate with a graduation-level performance-based assessment. Our goal is for the Beacon graduate to understand that the study of mathematics is an invaluable tool for developing both a disciplined and an imaginative approach to accomplishing their goals.
