    Abstract

    This study aims to produce a learning trajectory in the division of fraction. The Indonesia Realistic Mathematics Education (PMRI) that affiliated with thematic integrative learning curriculum 2013 was selected as the research approach. Design research that consists of three stages; preliminary design, teaching experiments, and retrospective analysis was chosen to achieve the research objectives by designed Hypothetical Learning Trajectory (HLT). The HLT was tested on 34 students of class V SDN 179 Palembang. The results showed that the given designed activities can stimulate informal knowledge and it provided the information about students’ prerequisite knowledge as a bridge in understanding division of fractions. Completing symmetrical patterns from the given partial part of the patterns can stimulate students to understand the concept of reciprocal or multiplicative inverse. Moreover, by partitioning the area and the set of objects, students’ models and representations on the partitive problems are observable. Furthermore, students’ strategies have developed gradually to a more formal mathematics. In which the students used the area models as a model of partition situation. The more formal reasoning such as ratio, repeated addition, and multiplication are the model for, that bring the students to the rules of division of fractions what so called invert and multiply algorithm
