Abstract


The realistic mathematics approach provides students with the opportunity to discover and reconstruct mathematical concepts. This research aims to reveal the analysis of the implementation of the realistic mathematics education approach to the lesson on measuring angles in triangles. This study is a descriptive qualitative research conducted at SD No.038/XI Koto Lolo with 31 fourth-grade students as subjects. Data collection techniques in this study include observation, documentation, and interviews. The results of this research show that students are able to use the protractor correctly in measuring angles. Furthermore, students also discovered the concept that the sum of angles in a triangle is 180°.


Keywords
