The Lower School adopted Math in Focus (Houghton Mifflin’s version of Singapore Math) in 2008. The program follows a framework emphasizing concept mastery, a concrete-to-pictorial-to-abstract approach, metacognitive reasoning, and the use of model drawing to solve and justify problems.
The Lower School Mathematics Program, Math in Focus
, emphasizes mastery of basic mathematical concepts, number sense, mental math and problem solving. Math concepts are presented in a context meaningful to the students moving from concrete objects to pictorial representations to abstract algorithms. Fewer topics taught in greater depth at each grade level help students understand the “how” as well as the “why.” Students build mathematical meaning and fluency to provide a solid conceptual foundation for problem solving.
