Introduction: the research problem consisted of identifying the capacity measures involved in the processes of the artisanal practice of cob bun making in the Pinar Del Río neighborhood in the city of Barranquilla, in the department of Atlántico. The general objective was to know the non-conventional capacity measures present in the elaboration of the corncob bun in the municipality of Barranquilla, Atlántico. The methodology used is qualitative type with ethnographic design based on participant observation, using semi-structured interviews, with the use of audiovisual recording devices, which was carried out in two visits to the artisan. The theoretical references are framed within the framework of the Ethnomathematics Program. The main results are the use of nonconventional capacity measures such as the bucket, the bulk, the scoop, the cup, among others; other practices are also immersed in this activity. The discussion is based on the use of patterns of similar non-conventional measures found in other craft practices and different socio-cultural contexts. Also, the relevance of problematizing the results obtained in the classroom is considered. [ABSTRACT FROM AUTHOR]
