In this paper we focused at contents of "literal expression". And we made a content of "transformation of equation about the primary and the subordinate variables" in them. Moreover we examined it through a educational practice. It follows from the result that 6th graders could understand the contents easily and they could put it to practical use too. And it was found that the contents were very significance for 6th graders on 2nd stage of partnership between elementary school and junior high school.
