Saberes matemáticos na agricultura do povo Potiguara da Paraíba: uma abordagem etnomatemática sobre o ensino de medidas no 6º ano do ensino fundamental

Abstract

This study investigated the mathematical knowledge present in the cultivation activities practiced by the Potiguara Indigenous People of Paraíba, in the municipality of Marcação-PB, and its relationship with the mathematical concepts of the “Quantities and Measurements” thematic unit of the BNCC (Brazilian National Common Curricular Base). The research is characterized as fieldwork and was carried out in three villages in the municipality of MarcaçãoPB through interviews with local farmers, as well as observation and recording of their agricultural practices. Data analysis made it possible to identify different ways of measuring quantities such as length, area, time, mass, and amount, using traditional units such as the braça (vara), the “bundle of beans,” and the “hand of corn.” The farmers’ work combines traditional knowledge with standardized conventional measurement units, revealing a living Mathematics built upon cultural influence and capable of being integrated into formal education. The results of this study showed that the agricultural practices of the Potiguara people can dialogue with the knowledge objects and skills proposed by the BNCC, enabling the development of a didactic proposal that includes the direct participation of students through a field class, problem-solving activities in the classroom, and the sharing of acquired knowledge. This promotes the appreciation of local knowledge and reinforces the importance of Mathematics teaching connected to students’ reality and cultural diversity.
