<![CDATA[Students often find it difficult to understand abstract mathematical material and do not find relevance in everyday life. This study aims to develop ethnomathematics-based mathematics teaching materials on the subject of plane figures using the Borg and Gall development model. Etno aims to strengthen understanding of the material and concept of plane figures in grade 3, through historical objects or places. Learning materials are developed based on materials that are easy for students to understand, adapted to mathematics subjects and the application of mathematics that is deeply rooted in the social environment. Respondents in this study were grade 3 students of SDI Al Ghaffar. The results of this ethnomathematics-based teaching material development research were measured through a pre-test evaluation with an average value of 61.17, the frequency of students still getting low scores, then after conducting the experiment, a post-test was conducted, the results of the post-test assessment showed an average student score of 78.82. An increase in learning outcomes was found before and after students learned using ethnomathematics-based mathematics teaching materials, so that the developed Ethnomathematics-Based Teaching Materials were effective in strengthening the understanding of plane figure material. As a result, this study suggests that elementary school students can gain better conceptual understanding through locally based mathematics instruction. This study was limited to one school and covered only plane geometry.]]>
