Introduction: Gender category associated with sex veil sociocultural constructions enclosed in this conception. It is necessary to intervene in it since childhood by rethinking it as identity, role, stereotype and gender relations beyond male and female. Thus, we questioned: What cultural representations of gender can be captured by children and adolescents in photographic images? Objectives: To determine the cultural representations about genders among children and adolescents in an elementary school, captured by photographic images. Method. Research-action-extensionist developed at an elementary school in Rio de Janeiro, with two groups of school age (6 to 10 years old). In the expression workshop was implemented the dynamics of creativity and sensitivity PhotoVoice and in the creation,  was organized the photographic exhibition. First, they learned basic rules for photographing, then they were divided into groups to photograph the school's movement, which reflected gender categories, with five cameras, during 20 minutes. In the "assemblies" (two), by voting photographs were chosen, subtitled, and named the exhibition. Results: Social representations of gender reflected on the groups selected, according to aesthetics and artistic-theoretical production, of images of power relations. Women were working as cleaner and men as concierge and security guard. In the playground, boys and girls have grouped by sex with few movements of ruptures (girls playing soccer with boys); with discretion, one sees boys sharing the doll's play. Conclusion: From the reflection on gender in school, the possibility of acting in the daily life validates "roles" and stereotypes that favor the inclusion of gender as a strategy for health promotion.
