Formation of concepts in Geometry and Algebra by a student with visual disability. Ciência educ. [online]. 2017, vol.23, n.4, pp.867-879.

The present research has as its principal aim to search for an alternative to develop mathematical concepts with a completely blind student, which may be meaningful and that contribute for her learning and development. The research presents a qualitative approach, using the case study as its strategy. It was carried out in a non-governmental institution that offers specialized care in the visual disability area, in Guarapuava, in the interior of Parana State. Based on Vygotsky's cultural history theory, we conducted a pedagogical intervention so that the student could elaborate concepts of Geometry and Algebra. The results showed that the student consolidated mature concepts, producing new ones from them. It was possible to perceive that, in spite of their limitations, students with visual disabilities are able to elaborate concepts that are necessary for their autonomy and social participation.
