Perhaps more than any other subject, mathematics is cumulative; students layer new concepts onto previous learning. The pace of moving forward within the curriculum, therefore, is guided primarily by students’ genuine mastery of foundational material. Teachers design learning experiences that encourage curiosity and engender intrigue, providing students with many opportunities to synthesize their learning. At Ursuline, students develop a robust problem-solving ability, with emphasis on demonstrating advancing critical thinking capacities as they work toward solutions. Courses are designed to appropriately challenge students, meeting them where they are and encouraging them to take risks. The satisfaction that comes from successful engagement with the material in real-world applications is palpable, and highlights students’ developing abilities to draw on mathematical thinking practices and knowledge in a broader context.
