Contribuições da teoria da objetivação para a análise do planejamento de tarefas de um professor de matemática envolvendo alunos com transtorno do espectro autista.

This article aims to understand aspects of teacher planning that enhance the possibility of meeting students with Autism Spectrum Disorder (ASD) with mathematical knowledge. It is a qualitative research, having as main data collection instruments a semi-structured interview and task planning documented by a teacher. Based on the analysis of the teacher's planning, the subject of the research, the contribution of the theoretical framework is discussed, Theory of Objectification, idealized by Luis Radford, which provides fundamentals that guide the task design component, a component that translates as the project teacher's teaching. There are three categories: general considerations, considerations on mathematical problems and considerations on forms of human collaboration. In conclusion, the categories of analysis emerging from the elements of the task design component allowed identifying aspects of the teacher's planning that enhance the possibility of the student with ASD encountering mathematical knowledge, such as: considering prior knowledge that emerges from situations experienced in their daily; explore contexts that allow the student to encounter mathematical knowledge in a utilitarian way; and explore different physical environments, providing coexistence with appropriate rules and behaviors and the generalization of school knowledge.
