This communication relates to the three-year case studies of three elementary and secondary school teachers who returned to formal education to take a masters course aimed at improving their professional practice. In this work we present the case of Delia, a fifth grade teacher who carried out a development project dedicated to the teaching of fractions as measures. The research problem that defines this case is the recognition of how she addressed the teaching of fractions, what teaching difficulties she experienced when engaged in that practice and on what bases did she structure the planning of the instruction process. The fundamental methodological follow-up instruments were interview and observation, from which this case study is drawn.
