In this article, we present a discussion about a research conducted by students of Degree in Mathematics, which focused the development of the visualization ability and the geometric thought in the carrying out activities that contemplated geometric constructions of three - dimensional surfaces using pencil, paper and computational tools. Activities were elaborated, applied and analyzed and these activities articulated theory and practice through activities of investigation, exploration, visualization and construction of surfaces. The articulation between Algebra and Geometry and the use of transversal sections, present in the activities, sought to make the students develop the ability to visualize three- dimensional objects. The use of educational informatics through Winplot allowed the exploration and formalization of different geometric concepts, from the rotation and translation of figures, which facilitated the geometric visualization with multiple representations. The qualitative analysis of the results confirmed that the students had a better capacity for generalization and that the activities showed a more progressive and innovative way of teaching Mathematics in situations of practice and experimentation of the content, aiming at understanding and interpretation of the topics that are studied.
