Ethno-mathematics-based learning is designed to focus on material that is related to the culture of the area where students are located. Many students do not know the terms of local village customs, especially terms that are mathematical measurements, even though these students are native to the local village. The purpose of this study was to determine the validity of student worksheets based on ethnomatematics based on geometry and measurement. This research took place at SMP Negeri 4 Sungai Penuh conducted in class VII with 159 students.
