A Formação de Professores para a Compreensão dos Números Inteiros nos Anos Finais do Ensino Fundamental por meio do Estudo de Aula

This article aims to understand how teachers perceive the difficulties in teaching and learning integers, based on the perspective of Lesson Studies, applied in the 7th grade of elementary school. To this end, we present part of a broader doctoral research, which adopted Lesson Study as a teacher training methodology. The research, of a qualitative nature, used the formative procedures of Lesson Studies: study, planning, observation and reflection of a lesson in a private school in the city of Santo André, in three classes of the 7th grade of the final years of elementary school, with the participation of two mathematics teachers. Among the results of the research, an improvement was observed in the teachers' analyses in identifying the students' difficulties, supported by the theoretical references discussed throughout the training.
