Generally speaking, people emphasize that elementary school children should be taught just basic mathematic fundamentals and knowledge, such as basic calculation or understanding the names and the properties of simple diagrams. In such lessons, teachers teach mathematics lessons in a way that children do not think deeply about mathematical maters, that is, children just learn the procedures of calculation, the properties of diagrams, etc. I am sure that children should learn basic and fundamental skills and knowledge, however, such lessons do not promote interest and appreciation of mathematical learning. I think that children do need to think for themselves and act for themselves through mathematics lessons in addition to mathematic fundamentals.
Then, how can we foster children’’s abilities to think and express themselves mathematically I will present my fundamental ideas and an actual record of lessons.
