Saxon math, developed by John Saxon, is a teaching method for incremental learning of mathematics. It involves teaching a new mathematical concept every day and constantly reviewing old concepts. Early editions were deprecated for providing very few opportunities to practice the new material before plunging into a review of all previous material. Newer editions typically split the day's work evenly between practicing the new material and reviewing old material. Its primary strength is in a steady review of all previous material, which is especially important to students who struggle with retaining the math they previously learned.

In all books before Algebra 1/2 (the equivalent of a Pre-Algebra book), the book is designed for the student to complete assorted mental math problems, learn a new mathematical concept, practice problems relating to that lesson, and solve a varied number of problems which include what the students learned today and in select previous lessons -- all for one day's class. This daily cycle is interrupted for tests and additional topics. In the Algebra 1/2 book and all higher books in the series, the mental math is dropped, and tests are given more frequently.

The Saxon math program has a specific set of products to support homeschoolers, including solution keys and ready-made tests, which makes it popular among some homeschool families. It has also been adopted as an alternative to reform mathematics programs in public and private schools. Saxon teaches familiar algorithms and uses familiar terminology, unlike many reform texts, which also contributes to its popularity.

Replacing standards-based texts

By the mid 2000s, many school districts were considering abandoning experiments with reform approaches which had not produced acceptable test scores. For example, school board member Debbie Winskill in Tacoma, Washington said that the non-traditional Interactive Mathematics Program (IMP) "has been a dismal failure." Speaking to the board, Mount Tahoma High School teacher Clifford Harris noted that he taught sophomores in another district Saxon Math, and their Washington Assessment of Student Learning scores have continually climbed. Unlike IMP, Saxon program gives students plenty of chances to review material so they retain their skills, he said. In September 2006, Tacoma Public Schools introduced the Saxon books district-wide and rejected the previous IMP textbooks.
