Odyssey Math is a web-based program developed by Compass Learning for mathematics instruction in kindergarten to grade 8. The program includes a mathematics curriculum and formative assessments designed to support differentiated and data-driven instruction. Based on assessment results, the program generates an individualized sequence of mathematics topics and skills—a “learning path.” Odyssey Math was found to have potentially positive effects on achievement for primary students.
