The CESJDS Lower School math curriculum consists of multiple inquiry- and context-based units that are meant to motivate and challenge students. There is a focus on fostering a deep conceptual understanding of essential mathematical ideas, strategies, and models while also engaging students in critical thinking, problem solving, and communication activities. The three major programs used are Contexts for Learning Mathematics, Project M2/M3, and SFUSD, with supplemental materials sourced from Jo Boaler, Greg Tang, Steve Wyborney, Marilyn Burns, and various other leaders in the field of mathematics instruction.   

Throughout all units, students develop grade-appropriate content standards with a special focus on the development of mathematical communication and critical and creative thinking skills in problem solving.
