Abstract

The purpose of this work was to report on the realization of an instrumental orchestration of the Percentage content in Elementary School - Final Years from the use of the Lesson Study Methodology in the context of PIBID. As a theoretical basis we took the theory of Instrumental Orchestration (IO) and the Lesson Study Methodology. The research has a qualitative approach with descriptive objectives with an action-research design. The participants of the study were 7th grade students of a public school in the city of Manaus - AM, data collection was done through observation, filming and student productions, while the analysis was done in the light of instrumental orchestration. The application of classroom tasks, with discussions and interactions, stimulated the participation of students, allowing them to share their doubts and anxieties regarding the content of percentage. In addition, the Lesson Study Methodology led the teachers to reflect on their practice, contributing to their professional development and future improvements. Through collaborative planning and reflection on the teaching practice, it was possible to identify and solve the students' difficulties, adapting the teaching to their needs.
