Investigando os conhecimentos matemáticos do cultivo da mandioca na Aldeia Três Rios em Marcação - PB

Abstract

The present study presents and analyzes the mathematical knowledge used by the indigenous group called Three Rivers, located to the BR 064, marking the city of the northern coast of Paraiba with regard to everyday activities associated with the production of cassava. The empirical part of this research consisted of a work of exploratory and descriptive in order to collect data to confirm the perspective of ethno mathematics used by study participants. During visits to Three Rivers community, especially cassava growers, it was found procedures and empirical forms of informal mathematics used. We conclude that this work has reached its ultimate goal, because the research question answered in the study, which analyzed the mathematical knowledge used by farmers in the Three Rivers community for cassava production. By analyzing the activities of farmers in production and marketing of cassava, it is clear that some steps contain specific mathematical knowledge. Therefore, include: counting procedures, measurement of lengths and areas; Measurement of volume, measurement time; Proportionality; Commercialization of cassava, the notion of parallelism and concept of calculation of perimeter.
