O ensino de fração no 7º ano do ensino fundamental utilizando como estratégia metodológica a “Medição com cordas”

Abstract

The present work is a study of the use of the methodological strategy of measuring with string to introduce the concept of fractional number and its representations in a class of the 7th year of elementary school II. Therefore, we understand that the mathematics discipline is considered by the majority of students as one of the most difficult, and the methodology used by the teacher may be one of the factors that corroborate this. In this regard, a study was made of documents such as the BNCC (2018) and authors that address the teaching of fractional numbers and the use of concrete materials as an alternative for teaching mathematical concepts, as well as the study of the strategy of measuring string for teaching fractions. Therefore, this work shows the results of a researcher inspired by action research, with a qualitative approach, in order to improve classes and consequently student learning, different alternatives must be considered and developed in the process of teaching and learning mathematics. In this perspective, practical classes were developed using the methodology of measuring strings, which in the investigation made it possible to perceive that the manipulation of the material provided a significance in the learning of 7th grade students.
