The didactic strategy integrates Van Hiele's model and GeoGebra to foster spatial visualization and geometric reasoning. Based on solid theoretical principles, the Van Hiele model structures levels of reasoning, while GeoGebra, as an educational tool, enhances the visual and interactive experience. This strategy focuses on the development of competencies, aligned with contemporary approaches to promote deep and contextualized learning in geometry. The didactic strategy designed is based on Van Hiele's model and GeoGebra, and mobilizes resources for educational change. Students face difficulties in identifying solids of revolution and visualizing in three-dimensional space, while teachers do not explore prior knowledge and the teaching strategy sometimes lacks guidance. Therefore, the purpose of the research was to design a didactic strategy to develop spatial visualization and geometric reasoning, oriented by the Van Hiele model with the use of GeoGebra in fourth grade students of the Educational Institution "Sacred Heart of Jesus" of Cusco.
