The aim of this Final Degree Project is to design, implement, and evaluate a teaching proposal aimed at second-year primary school students, based on the poetry of Gloria Fuertes, with the goal of promoting linguistic, expressive, and social skills. The study is set in the context of Spanish Language and Literature, using a Project-Based Learning (PBL) approach and cooperative learning. The methodology employed integrates play, oral expression, and creative development through poetry, using visual aids and digital tools. The proposal was applied in the classroom, observing its impact on student motivation, improvement in oral expression, teamwork, and the development of literary sensitivity. The results obtained show that poetry, especially that of Gloria Fuertes, is an effective resource for working across different areas of the curriculum, promoting creativity, self-esteem, and emotional involvement among students. It is concluded that incorporating active and contextualized literary proposals enhances meaningful learning and reinforces the connection between language and emotions.
