Etnomatemática das crocheteiras de Angical do Piauí: contribuições para o ensino contextualizado de matemática

Abstract

This work deals with a study concerning the ethnomathematical knowledge of the crocheters of Angical do Piauí. The objective of the study was to understand the knowledge and practices of the crocheters of Angical do Piauí in the production of crochet in its various formats and geometric aspects. For this, the following question is proposed: What ethnomathematical knowledge composes the knowledge and practices of the crocheters of the Recreio community of Angical do Piauí, in the production of crochet with string and lines? The study took place through the application of an interview with three women, with open questions prepared based on the research objectives in order to highlight the importance of these knowledge and mathematical practices of the crocheters for the community and the school. In addition, the research sought to describe the process of construction of the same and identify the ethno geometric models contained in the crochet. The research was implemented in two stages, which involved respectively the description of ethnomathematical knowledge and the classification of the geometric models contained in crochet. In general, the study records the techniques, procedures and artifacts that crocheters use in the production of each piece constructed. Finally, the possibility of geometric classification of crochets in the elliptical or mosaic type
