Abstract

Assuming the principle that through activities that motivate and challenge students, the learning process becomes easier, pleasurable and meaningful, this research presents a methodological proposal for teaching Geometry, which consists of using folding in triangles made of paper as a way to teach Notable Points of a Triangle. Thus, the purpose of this work was to propose, apply and analyze this methodology as a way of constructing concepts. Five activities were applied with students from the third grade of high school of Frei Othmar School, in the municipality of Santarém-PA. The data for analysis were collected from the researcher's field diary and the application of a questionnaire with the participating students. Therefore, this research presents a report of the experience lived by the researcher in the classroom and the students' conceptions about the proposed activity. The main results show that the proposed activity was useful and well accepted by the students. Its use made it possible for students to reflect on the mistakes made and learn with them.
