    This research aimed to investigate how Lego can support student’s understanding of equivalent fraction concept with area model in fourth grade. This study was based PMRI that associated with thematic integrative learning curriculum 2013. The method used was design research of type validation study that aimed to prove the theories of learning. This research consists of three stages; preliminary design, teaching experiments, and retrospective analysis were chosen to achieve the research objectives. The research was conducted on 21 fourth graders in SDN 16 Lembak. Students learning activities that were conducted including: 1) determine the fractions as parts of a whole using Lego which students get a fraction with take of Lego piece that covers the whole, and 2) determine the equivalent fraction of fractions formed from Lego which students compare area of missing Lego pieces and area replace parts. Understanding of equivalence fraction concept obtained from the size or area of missing Lego with replace part. This study was focus on first stage of the teaching experiment. The results of this study indicate that a series of activities can help students to understand of equivalent fraction concept. Keywords : equivalent fraction, Lego, PMRI approach, design research
