Resumo
Neste trabalho é contado um pouco da história da matemática, da história dos homens que construíram e desenvolveram a matemática. Isso foi possível devido a observação da realidade, da necessidade de solucionar problemas cotidianos da época, tudo através de experimentos reais e conclusões de acordo com os resultados obtidos. No âmbito escolar nota-se uma dificuldade muito grande pelos discentes na parte de matemática que trata sobre a trigonometria e também sobre os triângulos. Consequentemente, algumas atividades práticas foram desenvolvidas com os discentes do Ensino Fundamental II e Ensino Médio com o intuito de facilitar a compreensão deste tema e torná-lo interessante e agradável. Nestas atividades, os próprios discentes construíram figuras utilizando compasso, régua e transferidor, podendo vivenciar na prática as situações de aprendizagem, verificar os teoremas, opinar e até indagar situações diferentes, mas que encaixaram perfeitamente nas atividades propostas, propiciando uma aprendizagem agradável e duradoura.
The purpose of this study is to tell a bit of the history of mathematics as well as the history of the men who have built and developed its theorems. It was possible due to the observation of real situations, the necessity to solve contemporary problems through realistic experiments and conclusions according to the results achieved. In school environment it is noted a great difficulty that the students have in learning trigonometry and also about triangles. Consequently, some hands-on activities were developed among Middle and High School students in order to facilitate the understanding of this subject and make it more interesting and enjoyable. The students were presented activities in which they built figures (geometrical forms) using drawing compass, ruler and protractor. In doing that, they could experiment learning practices, check the theorems, give their opinions and even ask about different situations, but that truly suited to the activities suggested, providing an enjoyable and lasting learning.
