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.
