The premise of the present paper is that an intercultural approach to multilingualism in schools generates inclusion and a construction of cultural and linguistic identity that respects the diversity of society and classrooms. Students, teachers, and families participated in an action research project conducted in four schools with the presence of varied home languages. One of the objectives of the project is to foster intercultural education by introducing home languages in the school through identity texts. The process was documented through questionnaires, interviews with families and educators, and classroom observations. Results show that the texts and the curricular activities designed around them have provided spaces for the recognition and valuation of diversity. The self-esteem of alloglot students has improved and the collaborative relationship between school and families has increased. Conclusions point at the potential of multilingualism as a way to enrich the curriculum and to promote equality from diversity in the school context.
