Tabuleiro das expressões: um auxiliador do ensino da matemática para alunos com deficiência visual

Abstract

It is believed that the principle of inclusion is ideal to achieve great success with respect to teaching students with special needs. One of the concerns in math education for students with visual disabilities are in need of producing tailored and suitable for use in classroom teaching materials, especially in the regular room contributing to a better job of the teacher and also to a better understanding and participation by the student. After a brief reading articles and books related to the principle of inclusion, and more precisely when it involves the student with visual impairment and mathematics teaching, we realize that the reality of a regular classroom lacks educational resources that encourage learning. So we developed for students with visual disabilities (low vision and blind), which dominate the reading and writing of Braille system, a didactic material called "Expressions of the Board" which assists the process of teaching and learning of numeric expressions in mathematics classrooms. The "board of the expressions" consists of a tray and suede "rings Braille" by mathematical elements in Braille lettering compatible with the measurement cell. The tray has a rectangular shape measuring 29 cm x 34cm and allows attachment of rings. We believe that the use of teaching resources, being present in everyday school life of students with visual impairments, facilitates better understanding of the content being studied, providing greater learner autonomy in the classroom.
