In this article, we present an educational proposal designed to work on spatial geometry and three-dimensional thinking with students in the last years of Primary Education. The proposal is comprised of several activities that combine the use of a classroom videogame and working with manipulative materials to create a representation of the videogame in the real world. The final goal of the sequence is to design levels that could be incorporated into the video game. This exercise enables students to work on visualization and positioning in three-dimensional structures and on a problem-solving task.
