Ethnomathematics and ethnoscience offer contextualized knowledge by incorporating indigenous knowledge. Qualitative methods are utilized in this investigation of ethnomathematics and ethnoscience to identify educationally applicable cultural understanding and principles. Data collection was conducted through observation, interviews, and documentation. Mbaru Niang, a traditional abode in Manggarai Regency, exemplifies local wisdom through its unique architectural characteristicsan unconventional circular base, conical shape, smoke-infused food preservation methods, and utilization of natural building materials and its strange dimensions. A correlation exists between the traditional knowledge of Mbaru Niang and the lifestyle of the Wae Rebo community, in addition to fundamental educational principles, including geometry, food preservation measurement, and environmental conservation, according to the results of this research. Therefore, the researchers advise incorporating Mbaru Niang and Wae Rebo's ethnomathematics and ethnoscience activities into elementary school mathematics and science curricula.
