GeoGebraBook is a pedagogical resource in the form of a digital book created and developed for free on the GeoGebra online page. This paper presents preliminary research using GeoGebraBook to support explaining the area of a flat figure and the volume of a solid. The study was based on qualitative and quantitative research and involved forty-four Primary school students. Findings suggest that students are receptive to an exploration of GeoGebra applets, get involved in tasks and declare advantages using GeoGebraBook for their learning. The students identified the problem, investigated, debated, interpreted and produced possible justifications and solutions. We observed that the students collaborated to solve the proposed questions in a playful way. This didactic proposal proved to be an enriching experience for students. It served as a basis for the development of a new procedure for the consolidation of mathematical concepts based on the GeoGebra dynamic geometry app.
