N2 - In this study, we investigate at how two types of visual representations -the Double number line, and the Ratio table affect students’ performance on percentage issues. In this study, 572 Japanese primary school students in Grades 4, 5, and 6 were given proportion problems with representations such as the “Double number line” and the “Ratio table diagram.” As result, the effect of them does not exist in Grades 4 and 6. However, re-orientations have the greatest impact in Grade 5. All grade students could solve the Unit problem regardless of the presence of representations. The Double number line was a more effective representation than Ratio table diagrams. When students were shown these, they often solved problems by using a scalar or functional connection involved in the features of representation.
