Teaching Guide for Japanese Math Curriculum

This article from Mathematics and Multimedia. Japan has been well-known for its high achievement in Mathematics, particularly in the Trends in International Mathematics and Science Study (TIMSS).

For teachers who want to take a look at how Japan develop mathematical concepts, I strongly recommend that you read the following Teaching Guides for the Japanese Course of Study (the term used for curriculum). You may not agree with me, but I believe that can learn a lot from these documents. 

• Elementary School Teaching Guide for Japanese Course of Study
• Junior High School Teaching Guide for Japanese Course of Study
