The research aims to identify the mathematical elements implicit in traditional practices, such as geometric shapes, measurements, proportions, and symmetries, while valuing the knowledge of local masters. The methodology is qualitative, based on bibliographic research, interviews, and observation of the stages of instrument making, with analytical procedures that approximate ethnographic studies. The results show that the knowledge applied in the construction of the curimbó involves relevant mathematical reasoning that can be used as pedagogical strategies for teaching Mathematics in a contextualized way. Equally important, they highlight a set of ancestral knowledge and practices of a people who organize their social life around the practice of carimbó. Therefore, Mathematics is essential in the production of the curimbó, as it establishes a bridge between local knowledge and scientific knowledge. It allows traditional knowledge to be transformed into concrete and applicable measurements, functioning as a tool of precision capable of organizing, calculating, and structuring each detail with millimetric accuracy.Acesso AbertoEtnomatemáticaCurimbóCultura popularEthnomathematicsPopular cultureCNPQ::CIENCIAS HUMANAS::EDUCACAOTrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
