    Students of elementary school still have difficulties to understand the concept of percentages. Therefore, this study aims to figure out how teacher can support students to understand the concept of percentages: 1) students show an awareness that percentages are related to something; 2) students are able to compute the part of a whole while the percentage is given; 3) students are able to compute a whole if its part and its percentage is given. The study was conducted before students learned percentages formally in class, and then they only have their pre-requisite knowledge about fractions and their own initial knowledge of percentages they found from their surroundings. Based on those aims, we use Design Research as a method. We develop a set of instructional activities which is exploring students’ initial knowledge of percentages. Besides, contextual situation based on Realistic Mathematics (RME) approach which are loading bar on a game, voting results, road repair, and discount problems was used to contribute to the development of students’ understanding of percentages. From those activities, students will shade the loading bar, estimate the position of percentage on a loading bar, divide bar into small pieces, and use percentage bar to compute percentages which are expected can support them in understanding the concept of percentages. The ongoing analysis of collected data shows that the designed learning activities can support students’ understanding of the concept of percentages. However, some students still struggled with the discount problems
