This study aims to develop Ethnomathematics-based Student Worksheets (LKPD) with Kalimantan Dayak Typical Culture, which is feasible as a mathematics learning media for grade VIII SMP Negeri 7 Tarakan. The research method was Research and Development (R&D) with the ADDIE model, which consists of five main stages : Analysis, Design, Development, Implementation, and Evaluation. Howeve, this research only reached the development stage. The results showed that the LKPD meets the eligibility criteria for the material of relations and functions and the sytem of linear equation of two variables. The validator’s assessment shows that material experts provide a percentage of the feasibility of 71.40%, media experts 80% in the feasible category, and practitioners 97% in the feasible category. The students’ responses also showed a percentage of 84% in the feasible category. Thus, this LKPD is suitable for use as learning media
