The mathematics program at Lakehill Preparatory School is designed to guide students toward becoming skilled, thoughtful, and creative problem solvers who are able to utilize the tools of mathematics in other disciplines. The curriculum helps students acquire a rational understanding of mathematics by including age-appropriate activities with concrete materials and real-world applications.

The kindergarten through fourth grade classes use the McGraw-Hill My Math curricula, which emphasize the problem-solving skills and algebraic thinking that aid students in a smooth transition to higher mathematics. Creative demonstrations, hands-on activities, and class discussions emphasize the application of basic skills in daily experiences.
