Abstract
According to studies, students use addition in solving ratio problems. However, ratio relates to the notion of multiplication or division. To support students in learning ratio, especially the concept of multiplicative comparison and composed unit, we designed a local instruction theory which employs the double number line as the model. In line with the aim of the design research approach, the study aims at contributing on the innovation of instructional design. Five fifth graders of SDIT At Taqwa participated on the first cycle of the study. During the learning, the students were able to express the notion of multiplicative comparison and composed unit using the double number line. The result of the analysis of the study implies that the local instruction theory which employs the double number line supports students in learning ratio. Key Words: ratio, scale, double number line, composed unit, multiplicative comparison, RME, local instructional theory
