This article presents results of a research developed in the year 2016 and aims to recognize potentialities and limitations of the use of an accessible concrete material for the teaching of operations with polynomials in a regular class with blind students. In order to introduce the theme, present considerations on inclusion in legislation; the language of the visually impaired; the role of the teacher in relation to the teaching of these students; the use of manipulative materials and conceptions of algebra and algebraic education. Methodologically, the research materializes with the elaboration of a material accessible to blind students for the teaching of operations with polynomials. This material was used in a teaching sequence developed during eight classes with an eighth grade class from a public school in Curitiba. As potentialities, it was observed that the use of the material made possible the inclusion of the visually impaired student, besides motivating and facilitating learning about representation and operation with polynomials for all students in the class. It is highlighted as limitations the need to assemble the material, which can be done by teachers and students; and the mathematical conceptual error in relation to the possible representation of monomials given the characteristics of the material used.
