Based upon an ethnographic study of children's break time in a primary school in São Paulo, this article analyses the gender relations among children from 7 to 10 years old. We focus on the conflicting relationships between the sexes in an attempt to show the multiple forms of power play hidden behind apparently similar actions. By articulating the concept of conflict with simultaneous meanings of aggression and joking, we use the concept of "gender play" as one of the possible ways of sociability between boys and girls.
