In this research, I focus on the organizing activity by Freudenthal as mathematical activity on the secondary education for making improvement. Freudenthal mentioned that local organization is necessary logically. In mathematical education in our country, local organization is taking place in geometrical region and it is connected with B closely. However, Compared with geometrical region, organization in algebraic region was not elaborated. I consider local organization in algebraic region while turn up it in geometric region, identify of assignment is this paper's aim. In conclusion, I suggested that there is an assignment that should establish level between algebraic operation and local organization that Freudenthal and Okada (1977) mentioned. It is reason that the fundamentals for organization as weighting to master way of calculation in algebraic region are poor unlike geometric region, in algebraic region.
