- The Cartesian coordinate system plays an important role for children either at school or in their daily lives such as graph work and map reading. Signifying that importance, however, the Cartesian coordinate is commonly introduced as a ready-made system that leads to a lack of students’ understanding because they are merely asked to remember the rule and the notation. For this reason, a set of instructional activities are essentially needed to have students encounter and understand the concet by themselves. In the current study, design research is chosen as a study approach and the instructional activities are designed based on realistic mathematics education (RME) theory. This study involves four students of grade 5 in SD Pusri Palembang, Indonesia. The results show that students were able to specify the location of points on the positive quadrant of the Cartesian plane by using the ordered pairs. In addition, they were able to describe the location of points, which has zero and/or half as one of its numerical coordinate. This shows that the designed-learning can support students’ understanding in specifying the location of points on the positive quadrant of the Cartesian coordinate system.
