    The concept of multiplication is usually misinterpreted by students. In primary school, the concept of multiplication are usually given right way to students without allowing them to develop it by themselves. It affects the students that they will difficulties to solve problems or story problems in daily life. Providing experiences with variety multiplication problems, especially in contextual situation, is extremely useful. This raises the need to design an instructional sequence that allows students to develop the concept of multiplication by plaiting karet yeye.The aim of this research are to know students’ understanding about concept of multiplication through Hypothetical Learning Trajectory (HLT) which is designed with plaiting karet yeye as starting point and produce learning trajectories in multiplication using plaiting karet yeye context from informal level to formal level for grade 2. A series of two activities in HLT were designed by using PMRI. This research involves 6 students in the pilot experiment, 29 students in the teaching experiment, and one teacher of grade 2 in SD Negeri 98 Palembang. The method applied is design research with 3 phases, preparing for the experiment, design experiment, and retrospective analysis.The result shows that the series of activities could stimulate students to construct their prior knowledge about multiplication from informal level to formal level. The students understand the concept of multiplication as repeated addition correctly through plaiting karet yeye. The learning trajectories consist of 2 activities. Those are plaiting rubbers become karet yeye and counting how many rubbers to make karet yeye. Keywords: Plaiting Karet Yeye, Multiplication Concept, HLT, Design Research
