Uma abordagem da trigonometria no Ensino Fundamental, tendo a história como recurso didático

Abstract

This work exposed the story of the development and implementation of a didactic sequence to an approach of trigonometry in elementary school having the history of mathematics as a teaching resource. This sequence was developed in order to meet the recommendations of the National Curriculum Parameters (PCN). Brief biographies are presented a few mathematicians who were striking in that topic of mathematics and some practical methods used by them. Are highlighted, in addition, some definitions, properties and some theorems that are necessary for the development of trigonometry in Elementary Education. Then it goes to the account of the seminars presented by the students on the History of Trigonometry, with the use of slides and videos on the topic. Finally, it is presented the way in which the students made some experiments to calculate the height of some objects using the theodolite as an instrument, which provided a link between the history and practice.
