The Lower School mathematics curriculum is planned to help boys understand number concepts, the structure of number systems, numerical relationships and number operations, as well as patterns and functions, geometry, probability, data collection and measurement. The boys are encouraged to formulate generalizations about patterns and structure in mathematics and to develop their awareness of the way they use mathematics in their lives. Working in small groups, boys develop their mathematical thinking through problem solving, reasoning, communicating and representing their ideas. Recognizing that the larger part of a child’s understanding at this age is still bound to concrete experiences, the Lower School mathematics program uses manipulative materials as a foundation for teaching boys the basic operations of addition, subtraction, multiplication and division. As the boys engage in mathematical investigations, they are encouraged to think of multiple solutions to ensure deeper understanding. The playing of math games enables boys to grasp new concepts and develop fluency with number relationships. Daily classroom math activities are supplemented by weekly lessons in the math lab for each boy.
