**"An educator who conceived ways to make mathematics enjoyable"**
Kei Toyama was a Japanese mathematician and Professor Emeritus at Tokyo Institute of Technology, well-known in the field of mathematics education. He aimed to change how mathematics is learned and devised a new method called the "Water System." Its effectiveness surpassed that of the Ministry of Education's mathematics textbooks at the time.
As a mathematician, Kei Toyama aimed for students to genuinely enjoy mathematics, rather than focusing on "theoretical mathematics" that required proof. He discovered a mathematics education method called schema, which led to the development of the "Water System."
His numerous books on reforming mathematics education include "What is the Water System?" and "What is Quantity?" His representative works are "The Origin of Numbers - A History of Numbers," "The World of Two Dimensions - Plane Geometry," and "The World of Three Dimensions - Solid Geometry."
Q: What was his contribution?
He contributed to the reform of mathematics education and made an impact on society.
Q: What are his famous works?
The "Water System" and the "Theory of Quantity" are well-known. Kei Toyama aimed to change the way mathematics is learned, thereby making it enjoyable for many students and teachers.

Its effectiveness was higher than that of the Ministry of Education's mathematics textbooks at the time.
As a mathematician, Kei Toyama aimed to help students actually enjoy mathematics, rather than focusing on ``theoretical mathematics'' that required proof. He discovered a mathematics teaching method called schema, which led to the creation of a method known as the ``water system''.
He has written many books about reforming mathematics education, such as ``What is the water system?'' and ``What is quantity?'' His representative works are ``The Life of Numbers - History of Numbers'', ``The Two-Dimensional World - Planar Geometry'', and ``The Three-Dimensional World - Solid Geometry''.
Q: What did you do?
Contributing to the reform of mathematics education and having an impact on the world.
Q: What are your famous works?
The "Waterworks Method" and "Quantity Theory" are famous. Kei Toyama aims to change the way mathematics is learned, thereby making it enjoyable for more students and teachers.
