In many classrooms, children behave in rude and hateful ways. According to the American Association of University Women (AAUW), "Sexual harassment of girls by boys--from innuendo to actual assault--in the nation's schools is increasing" (AAUW, 2001). In this article, the author features the anti-bias curriculum approach to building friendships and relationships in the classroom. Through anti-bias curriculum, children learn to think more critically, empathize with each other, get along with others who have different points of view and cultural traditions, and take pride in their own heritage. The anti-bias friendship unit results in less bullying and sexual harassment between the genders. The author provides sample lesson ideas and books to go along with the unit.
