Acesso em:.https://repositorio.ufpa.br/handle/2011/2677The aim of this research was to investigate the know-how in the production of rabecas in Bragança-PA and the mathematical relations proceeded by this context. The empirical research was constituted by systematical observations of the process of artisanal production of rabecas, considering the artisans’ practice. From the ethnomathematical viewpoint, the research occurred through filming, interviews and photo records of their relationship with the local culture, highlighting the Marujada Festival which happens every year in Bragança, whereabouts the rabecas are part of this tradition. This research search for the comprehension of the traditional know-how in the production of rabecas and the mathematical knowledge that are established as an organized knowledge, with a logic that is parallel to science, however completing it at the same time. The methodological concepts were based on the principles of qualitative research made in-loco, when the process of production of rabecas was accompanied in all the stages. The ethnomathematics was the theoretical support used to comprehend the field observation. The results showed us that the artisans have a unique logic for measuring and establishing mathematical comparisons using parts of the body and the senses such as hearing, seeing and feeling. The knowledge of masters in producing rabecas is only a different way to think about the empirical knowledge as part of science ans the mathematical know-how, commonly taught by formal education.porAcesso AbertoEtnomatemática (Indigenismo)MatemáticaCultura popularArtesanatoBragança - PAPará - EstadoAmazônia brasileiraO saber-fazer dos artesãos de Bragança-PA por uma abordagem etnomatemáticaDissertaçãoCNPQ::CIENCIAS EXATAS E DA TERRA::MATEMATICA
