Through the use of puppetry with objects as an educational strategy, the Chilean Theater Company PerroBufo, specializing in linking theater with education, is developing a case study in Primary education. The goal is to assess how boys and girls, through a process of creating puppets with objects, are able to reflect on identity and gender equality. This research has enabled students to develop creative, expressive, and socio-emotional skills. Theater has contributed to the acquisition of critical thinking competencies among primary students, encouraging them to reflect on gender perspectives and stereotypes.
