Abstract: This study examines the use of realistic mathematics approach in improving the understanding of the concept around a rectangular circumference with Realistic Mathematics Approach in class III SD. The results showed that the learning material and the concept of a rectangular circumference Approach Realistic Mathematics can make the students relaxed, happy, and not tense in learning. Lessons are conducted by: (1) shows the objects that are around rectangular and non-rectangular; (2) students complete worksheets using props that have been given; (3) Each group presented the results of their discussion while the other students respond; (4) students construct a rectangular circumference through the guidance of teachers; (5) students solve problems and other realistic problems. Based on the research findings and the provision of the act of learning, it can be concluded that learning by applying realistic mathematics approach can enhance students' understanding of the material around the rectangle.
