Saxon Geometry was not published by John Saxon. It was published by Houghton Mifflin Harcourt, who purchased Saxon a few years after John's death (1996). The integration of geometry and algebra was one of John Saxon's fundamental principles. Because He was adamantly opposed to teaching geometry and algebra separately because students lose fluency in algebraic skills, This makes Algebra 2 and upper-level math courses more difficult and negatively affects standardized test scores.
