Saxon math book lessons are available online for grades K-12. The lessons are usually available in PDF format and can either be viewed on a web browser or downloaded.
Certain Saxon math book lessons can be accessed on some independent educational websites for no charge. However, the validity of such lessons cannot be guaranteed. The lessons can also be purchased directly from the publisher, Houghton Mifflin Harcourt, along with hard-copies of the textbooks. The Houghton Mifflin Harcourt shop also offers some downloadable sample lessons for algebra and geometry, which are designed for grades K-5 and 6-8, respectively. This gives an introduction to the structure of the lessons and some idea of the type of content used.
