Integrating Ethnomathematics and Make-a-Match Model into Geometry Teaching Material Development

Introducing traditional culture through mathematics while contextualizing Math in ethnic elements is the innovative idea of ethnomathematics. This study applied the idea in developing Geometry teaching materials using the Ethnomathematics approach and Make-a-Match models. This research and development employed the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The subjects were 24 students of Grade 8 in a junior high school. The instruments utilized in this research included validation sheets, questionnaires, observation, and pretest-posttest. This research yielded teaching material in the form of students’ worksheets (LKPD) that achieves the criteria of being valid, practical, and effective.
