Resumo
The indices in mathematics, presented by national evaluations are not favorable, in the
classroom it is possible to notice the difficulty of students in understanding
mathematical subjects, configuring important research and discussion on methods of
teaching the discipline, even more at this time of COVID-19 pandemic that the world
faces and has direct reflections on school education. Thus, the general objective of
this study is to develop a collection of interactive activities on GeoGebra, which helps
elementary school teachers to demonstrate formulas used in the calculation of the area
of polygons. To achieve the outlined objective the methodological path followed by this
study was the realization of a research of applied nature; qualitative approach; as for
the objectives it is exploratory; in relation to the procedures it is a bibliographic research
with inductive method. Through the development of this research it was possible to
know some features of GeoGebra, such as the use of the application for graphical
representation of function, discussion on solving linear systems, the mutual
contribution between members of the GeoGebra community and the collaborative
development available through the software. In terms of dimension the material
produced is a prototype of a book that is divided into three sections, the first contains
applications for the use of the teacher in the classroom, in order to facilitate the
demonstration of the formulas for calculating the area of polygons and provide a tool
that facilitates the visualization and understanding of the formulas by the student. The
second section has practical activities for memorizing the calculation processes, and
the third section presents problem solving exercises. By being in possession of a
published material the user can access the creator's profile, search for the post and
make comments, criticisms or submit a change suggestion. It was concluded that the
elaboration of a collection of interactive activities in GeoGebra, which helps the
elementary school teacher to make the demonstrations of the formulas used in the
calculation of the area of polygons was developed and presented in the research
results, proving that the work achieved its main objective.
