Teaching and learning media constitute one of the most important categories of didactics. Their functions favor the objective-content-method relationship, as well as the organization of the teaching-learning process. Their treatment in Geometry classes raises the preparation of teachers and students, and achieves a more developmental process. The lack of these means generates insufficiencies in the students of the Bachelor's Degree in Mathematics Education at the University of Las Tunas that affect the teaching-learning process of Geometry. From an analysis of the teaching and learning means in the different study plans of the pedagogical specialties of Mathematics, as well as of the philosophical, sociological, psychological, pedagogical and didactic referents, a set of teaching and learning means of different generations was designed and implemented, for its treatment in the teaching-learning process of Geometry. The projection of quadrics and conic sections through the implementation of these media increased the understanding of geometric content and the quality of learning.
