THE PLANNING OF MANIPULATIVE MATERIALS IN THE CONTEXT OF LESSON STUDY IN CONTINUOUS TEACHER TRAINING FOR INCLUSIVE MATHEMATICAL LITERACY

Abstract

With the goal of exploring aspects of planning based on Lesson Study methodology to fit into the stages of developing, aligning, or adapting, and applying manipulative materials for inclusive mathematical literacy, we offer a continuous training for teachers. We propose a workflow that provides, at each stage of planning, theoretical foundations related to the curricula and the specific subjects of mathematics, as well as practical guidelines for the moments of planning and adaptation of manipulative materials with the help of a specialist in special education. From the results, we report on the work developed by two groups, respectively dealing with the concepts of fractions and number construction, targeting Early Years and Early Childhood Education students. We understand that the workflow provided participating teachers with autonomy and confidence, culminating in the elaboration, alignment, and adaptation of potentially inclusive manipulative materials that were used by the entire class, a characteristic we consider essential in materials with this focus. Teachers were provided with new knowledge about mathematical content, curriculum, and ways of approaching the classroom that can lead to improvements in teaching and learning in their future professional practice.
