Abstract
This paper focuses on the effective learning to understand the concept of the
area in the elementary mathematics.
In Japan, the school mathematics tends to be inclined to numerical calculation.
Because of that, it is generally said that the students have less opportunities to
understand various concepts of mathematics. This would be considerable issues of
students developing further mathematical thinking.
One such example is the concept of the area. In terms of the area education, on the one
hand, students develop the numeral calculation skills. On the other hand, they do not
deeply understand the concept of the area.
In response to this, we developed teaching materials and methods, and had the
classroom practices.
As a result, we confirmed that the teaching materials and methods elevate the students
to understand the concept, and it leads to the understanding of the concept of the
integral calculus in high school mathematics.
