In the first part of this article I present theorical contributions from various fields of knowledge concerning gender relations in the classroom among children and adolescents. In the second part, I present partial results from the field research conducted for my Master's dissertation, which took place in a public school in the city of Campinas, Sao Paulo State. The themes I analyze are: children's relations to differences of class, race, gender and other social markers; hierarchies of power in the classroom; and children's concepts on heternormativity.
