It is in Pre-School Education when students are introduced in the process of reading and writing, and so it is also when the greatest differences between pupils in the learning pace are noticed. This leads to a lack of confidence when performing their activities. Because of that, an attractive method has been designed, based on overcoming challenges that arise, which in turn allows to encourage the motivation of our students throughout their teaching-learning process. To this end, these authors have carried out a bibliographical research focusing on gamification as a didactic tool that can help develop students’ personal growth by means of a challenge-based learning methodology in an environment where games are the protagonist. The aim of this project is to unify confidence and gamification, believing that their existing connection can help improve what this project addresses precisely.
