Trabalhando os jugos em Trás-os-Montes e Alto Douro

Abstract

This paper presents some contributions to the identification of the existing processes in a mathematical artefact of the agricultural region of Trás-os-Montes and Alto Douro — the yoke. The main aims are: to collect material on traditional jobs endangered and to adapt it for its use in the classes of mathematics. We report the implementation of tasks inspired by the yoke in mathematics lessons of three classes of the 9th grade in a school of Vila Real in the year 2007/2008. This is a work in the field of etnomathematics, focusing on the study of the mathematical knowledge and know how of a traditional job. This research was based on a documental research about the yokes and interviews of yoke makers and carpenters in the region.
