O uso do papel diamante em demonstrações geométricas no ensino fundamental

Abstract

This study investigates the implementation of diamond paper as a teaching resource in Mathematics teaching, particularly in geometric demonstrations in the 8th grade of Elementary School. The main objective was to analyze how this tool can help explore geometric demonstrations at this level of education, combining different representations used in activities of this nature (visual; continuous text and algebraic language). The methodology adopted was qualitative, of a bibliographic nature, in geometric demonstration activities from the 8th grade textbook of the Teláris Mathematics Collection by Luiz Roberto Dante, published in 2018. We explored the use of diamond paper and concluded that, in our understanding, this adaptation can facilitate the teacher's work with geometric demonstrations in the classroom, facilitating their understanding by students, highlighting its importance for the education of Basic Education students.
