    This research reports on a new approach of students’ learning of the concept of angle by exploring the idea of vision lines. This approach enables students to work with written work and physical activities involving the idea of vision lines from which the concept of angle could be emerged. This research was conducted within the design research perspectives to support students in acquiring the initial concept of angle. A series of two activities was designed by using Realistic Mathematics Education (RME), known as Pendidikan Matematika Realistik Indonesia (PMRI) as the design heuristic. This research involves 38 students in the teaching experiment and one teacher of grade 3 in SD Muhammadiyah 6 Palembang, Indonesia. The results show that the two activities could bring the students’ learning gradually developed their understanding the concept of angle. It has been found that the notion of vision lines and blind spots play an important role in developing students’ understanding of the concept of angle. Keywords: spatial representations, physical activities, angle concept, Pendidikan Matematika Realistik Indonesia (PMRI), design research.
