The Grade 9 and 10 mathematics program builds on the elementary program, relying on the same fundamental principles on which that program was based. Both are founded on the premise that students learn mathematics most effectively when they have a thorough understanding of mathematical concepts and procedures, and when they build that understanding through an investigative approach, as reflected in the inquiry model of learning. This curriculum is designed to help students build a solid conceptual foundation in mathematics that will enable them to apply their knowledge and skills and further their learning successfully.
