Main Article Content


Mathematicians are interested to create visuals for illustrating mathematical results in the current teaching trend. This article presents how to use plane figure areas to illustrate arithmetic properties, which is a new and interesting approach, the so-called "proof without  words" [6] for mathematical properties. On that basis, teachers can give comments and implement them in their instruction under the constructivism theory, in order to actively explore and construct students’ knowledge, enhancing their creative thinking for meeting educational renovation requirements in the new period.
