This study deals with the development of a graphic representation tool as a way to support educational planning in an elementary school in the rural area of Brasilia (Brazil's capital), aiming at the implementation of an integrated action-research project focusing on hunger and nutrition. The graphic tool made it possible to promote dialogical-reflexive interactions among school teachers as to the identification of competencies and skills in elementary education curriculum and generating apprenticeship themes, scientific concepts, and educational activities. It also constitutes a useful tool for the teaching staff to realize the interdependences among the many school subjects, and to understand their practices, thus leading to self-evaluation with greater awareness for potential for transformation.
