OBJECT AND ACTIVITY MATHEMATICS IN SASAK CULTURE PRODUCT

Abstract

Ethnomathematics is an approach to mathematics learning that focuses on the mathematical practices found in certain cultural products. Therefore, this study aims to identify mathematical objects and activities found in Sasak cultural products. The research data were obtained through observation and a study of the 4th-grade elementary school mathematics curriculum. The results are as follows: First, the art tools (gendang beleq and rincik), handicrafts (ceraken, peraneq, and kre' sesek), traditional houses (bale terang, sangkep, and lumbung), and various motifs found in the royal houses in the Narmada and Mayure parks. Second, Mathematical objects that can be identified include flat shapes (squares, regular and irregular polygons, triangles, and circles), tiling, similarity, congruence, symmetrical plane shapes, and solid shapes (cubes and blocks). Third, mathematics learning activities include: observing and identifying mathematical objects, exploring patterns and relationships, classifying mathematical objects, and presenting work results.
