This work was carried out after the existing agreement between the Instituto Astrobiología Colombia and the Universidad Distrital Francisco José de Caldas, where said entity manifested itself as a support channel for teachers in training of the Physics Degree. The constant participation in the multiple events organized by the Instituto Astrobiología Colombia, allowed to acquire experiences, tools, strategies and methods to teach astronomy to primary and secondary students in a different and striking way. After a series of participations, the creation of a didactic sequence was proposed, under the theme of Exoplanets, with the aim of teaching and disseminating astronomy from the early stages of training.
