In this paper, we take the survey through both papers and recent reports to investigate points to be considered in developing the national mathematical curriculum. Then we suggest that to prepare the next national mathematical curriculum, we consider the method to deduce the math-dislike, the method to increase the power of problem solving etc. and also we construct a compact curriculum which contains most of important math items. In the process of developing the curriculum, we must have lively discussion with mathematicians, and especially with teachers.
