The purpose of this study is to examine the trend of mathematics education in Singapore. The following approaches were employed in this research. The first was to investigate the content of the mathematics textbook in elementary school. Another was to utilize my experiences in NIE (stands for National Institute of Education in Singapore) that were the base of the education research of Singapore for two months. As a result of this research, the following were clarified to me. In the textbook, many aspects that promote the thought of mathematics were in each area, and the thinking process was explained in much space. The textbook emphasized not only the application of mathematics to a real scene but also the advancement of the mathematical content. Although mathematics education was influenced from an international academic ability survey in recent years, it is necessary to reexamine the treatment of a real scene in Japanese mathematics education from the viewpoint of the improving mathematical thinking.
