D’Evelyn’s educational philosophy embraces the concept that mathematics is an essential component in the development of an educated mind. The study of mathematics develops and refines the use of logical reasoning skills. The disciplined approach to mathematics is readily extended to all other areas of thought, providing an essential element to many occupations and further schooling, especially in the sciences. The Saxon series is used in the math program. This series is based on the belief that students can master the concepts of math through daily practice. Each lesson contains only a few problems illustrating the concept introduced in that lesson. The remaining problems, which become increasingly more difficult as the year progresses, are a review of all previously presented concepts. Each lesson is thus a cumulative review, and the problems require that the students develop fluency in problem solving to successfully complete the lessons.
