In this paper, we studied the significance and the aim of mathematical activities in today's advanced information and telecommunications network society. We examined some previous studies, and formulated a hypothesis for our study. Then we created a lot of educational contents and teaching materials, and used them to teach children in schools.(e. g. mathematical perspective drawing, literal expression concerning programming, etc.) At the same time, we created some educational contents and teaching materials for "cooperative distance learning" and "mathematical modeling", and also used them to teach children in schools. The results of our study clearly showed the mathematical contents that are actually needed today, and achieved a measure of success.
