Mathematics


The Keys School math curriculum uses the Singapore Math three-step approach, where lessons methodically progress from concrete examples to pictorial representations to more abstract concepts. Typically, new concepts are introduced using stories, hands-on activities, and investigations. Next, concepts are translated into paper-and-pencil images and finally, into numerical and symbolic algorithms. Review occurs with games, quizzes, software, and homework. And finally, understanding of each concept is extended through exercises in problem solving and critical thinking. Our goal is to help students truly understand the principles behind the mathematics, so they're better able to succeed in advanced math classes in high school and beyond.
