Saxon Math is one of the most established and widely used homeschool math curricula in the United States, with over 35 years of proven results. Developed by John Saxon in the 1980s, it uses an incremental, spiral approach: each lesson introduces one small new concept, followed by a large set of mixed practice problems covering everything the student has learned up to that point. This constant, cumulative review is Saxon’s defining feature and the reason it produces strong standardized test scores.

The K–3 levels are teacher-led with scripted lessons and hands-on manipulatives. From grade 4 onward, the format shifts to textbook-based independent work. Each lesson includes a warm-up, new instruction, lesson practice, and a mixed review set. Tests are given every 5 lessons. The dual-numbered levels (like 5/4 or 7/6) indicate grade and ability placement — Saxon 5/4 is designed for average 5th graders or advanced 4th graders.

What to Know

The high school sequence covers Pre-Algebra through Calculus and Physics. Unlike most curricula, Saxon integrates geometry concepts throughout Algebra 1 and 2 rather than teaching it as a standalone course (though a separate Geometry edition is now available). Many families supplement upper-level Saxon with video instruction from Nicole the Math Lady or DIVE Into Math for additional support.

Saxon’s biggest strengths are retention and test preparation. Multiple families report significant SAT and ACT score improvements after switching to Saxon. The trade-offs are a visually plain presentation (black-and-white workbooks), long daily problem sets (30+ problems in upper levels), and a pace that can feel tedious for students who grasp concepts quickly. It’s not the right fit for every learner, but for students who benefit from routine and repetition, Saxon consistently delivers results.

Saxon Math is published by HMH (Houghton Mifflin Harcourt) and will remain in print through at least 2030. A strong used-book market makes older editions affordable. It’s available through most homeschool retailers including Rainbow Resource, Christianbook, and Amazon.
