The strengths of Sansu Math® grew out of the Japanese practice of Lesson Study, in which educators collaborate and create carefully thought-out lesson plans. The result of Lesson Study is a collection of deliberate lesson plans, which take into account years of student-teacher interactions. Teachers draw from their own experiences and those of their peers, and thus can be prepared for any response from their students. In other words, the teachers know more than the material they are teaching - they are also well-versed in the way that students learn the material.

Schools considering adoption of Sansu Math® will find the most success with a comprehensive plan for professional development. Although Koyo Publishing Inc.® does not provide professional development services, we work closely with providers Dr. Makoto Yoshida and Bill Jackson, who were instrumental in the development of Sansu Math®.
