O ensino da raiz quadrada de um número natural com o auxílio do material dourado em uma turma do 9° ano do ensino fundamental

Abstract

The teaching of Mathematics is often traditional and this way of teaching causes disinterest on the part of students, interpreting Mathematics as a difficult and complicated subject. Knowing that students have difficulties in mathematical concepts and, in a way, learning Mathematics, the use of didactic materials serves as a teaching resource, since this didactic aid can contribute to student learning and also help as motivators for teaching. and student learning. In this sense, this research aims to analyze the contribution of the golden material to the formation of the concept of square root in the 9th grade of Elementary School in the final years. In this perspective, the concept of the square root of a natural number was worked on with the use of the golden material, with Basic Education students, in a 9th grade class of Elementary School, in which students solved an activity that consisted of explore previous knowledge of Geometry and Algebra in order to understand the concept of square root of a natural number. Regarding data collection, this was carried out both at the Federal University of Paraíba - UFPB, campus IV (Rio Tinto), where a task and validation of the research instrument were applied, and at a state public school, located in the municipality de Mamanguape, in which a practical task was also applied, in which it was found that the use of the golden material contributed to the understanding of the calculation of the square root of a natural number.
