Ethnomathematics: Utilization of Crock, Ladle, and Chopping Board for Learning Material of Geometry at the Elementary School

Mathematics and culture are not mutually exclusive. They work well together. It is because the help of ethnomathematics. Ethnomathematics is a learning approach of mathematics seeking a cultural approach in mathematical concepts.  This study aims at exploring the shape of the crock (earthenware jar), ladle, and chopping board associated with learning materials of the two-dimensional and three-dimensional figure at the elementary school level. The research method used was descriptive qualitative, conducted adopting an ethnographic approach. The ethnographic approach consists of three stages: selection, writing and exploration. The study results found that the shape of the crock (earthenware jar), ladle, and chopping board contained mathematical elements, which are two-dimensional figure including circles and rectangles as well as three-dimensional figure including cuboid, cone and ball.
