The pedagogy used in Saxon Math is unique, effective, and research based. The authors of the Saxon Math series, John Saxon and Stephen Hake, recognized that smaller pieces of information are both easier to deliver and easier to learn. Rather than grouping topics into chapters, they separated complex concepts into increments and distributed them throughout each grade level. The result is a distributed approach in which instruction, practice, and assessment of concepts recur continually over the course of the program. Foundational research has shown that the distributed approach produces significantly higher levels of student learning than massed presentation. Saxon Math is the only major mathematics program on the market today that systematically distributes instruction and practice and assessment throughout the year, ensuring that students gain and retain critical math skills.
