What research says

American students and teachers are greatly disadvantaged by our country’s lack of a common, coherent curriculum and the texts, materials and training that match it Schmidt, W.H., Houang, R.T., and Cogan, L.S. (2002)
A coherent curriculum: A case of mathematics, American Educator.

The high performance of Japanese students in international mathematics assessments has been highlighted by the Trends in International Mathematics and Science Study (TIMSS) in 1995, 1999, 2003 and 2007. Explanations include student-centered, problem solving lessons; a focused, coherent, and rigorous curriculum and textbooks; and teacher content knowledge, which has prompted some researchers to recommend the development of focused and coherent curricula for improving teachers' content and pedagogical knowledge and student learning in the U.S.

For these reasons, Japanese standards and textbooks were carefully studied by U.S. researchers and educators and became an important resource for developing the Common Core State Standards for Mathematics.

Tokyo Shoseki's Mathematics International (Grades 1 to 6) textbooks, originally published in Japanese in 2011, are the most widely used elementary mathematics textbooks currently used in Japan. This series is the successor to the highly regarded textbook series, Tokyo Shoseki's Mathematics for Elementary School (Grades 1 to 6) textbooks. Japanese teachers use these textbooks to develop dynamic lessons using a structured problem solving (teaching through problem solving) approach to enhance the mathematical thinking and conceptual understanding of students. Due to the intense interest of our customers, we have once again made these resources available in English in a downloadable pdf format.

These textbooks:

  • Were written by Japanese mathematics educators, mathematicians, and accomplished Lesson Study practitioners.
  • Are translated into English and adapted for use by teachers, schools and students internationally.
  • Introduce a limited number of topics each year (focused).
  • Go beyond procedures to develop conceptual understanding.
  • Help teachers and students understand how lessons develop concepts within and across grade levels (coherence).
  • Are useful as teacher resources for mathematical content and pedagogy, especially when studied as an entire set (grades 1 to 6).
  • Are useful as teacher resources for studying and developing Common Core State Standards based curriculum.

They are a must-have resource for:

  • Teachers and Lesson Study groups
  • Professional developers
  • Supervisors, coaches, and facilitators
  • Researchers and curriculum developers
  • University professors and student teachers
  • Students and home-schoolers
  • After school and enrichment providers
  • Anyone interested in improving the teaching and learning of mathematics
These books are a tremendous resource for teachers, no matter what curriculum you use, to enhance mathematical and pedagogical understanding and provide the U.S. mathematics Lesson Study communities with the same resources Japanese teachers have used for many years.

In my more than 20 years of conducting Lesson Study, these mathematics textbooks have been the main resource my colleagues and I have used to develop focused student centered lessons. I am happy my American colleagues will now have access to this valuable resource. Akihiko Takahashi, Associate Professor of Mathematics Education, DePaul University
