O livro didático de matemática e o ensino de triângulos

Abstract

This work aims to analyze the content of Triangles, in the Geometry section of the textbook for students in the 6th year of Elementary II. The textbook referred to was the Mathematics in the 6th year of Elementary School, in the Perspective of BNCC/DRC Skills - Lucas do Rio Verde/MT, produced by: Welvesley da Silva Santos, Sinelza Gonzaga de Melo Azevedo and Márcio Urel Rodrigues. The analysis of the considered text was based on pre-established criteria and fulfilled the underlying function of the analysis work: the analytical -descriptive function, where the strengths and weaknesses of the work were pointed out. This research was based on Gerard Vergnaud's Theory of Conceptual Fields and Raymond Duval's Theory of Semiotic Representation Registers. The analysis process revealed that there is a certain consonance with the above mentioned theories.
