Use of geogebra for the development of skills with geometry topics in the 9th grade of elementary school final years

This research presents the benefits of GeoGebra for the development of skills with Geometry topics in the 9th year of Elementary School final years, in an attempt to minimize the deficit in the teaching of geometric contents. The development of this research was based on the skills and competences of the National Common Curricular Base, with challenges and proposals being elaborated in the GeoGebra software to demonstrate the contents and their applications in a more concrete way. As the application is interactive, dynamic and has been used as an important tool for teaching and learning geometric content, we seek to make this resource a didactic strategy for teaching this thematic axis in an attractive and motivating way for students and for Mathematics teachers. a teaching aid.
