The work Blind students in the teaching of mathematics studies the way of integrating blind students into the teaching of mathematics, the way of communication and understanding of mathematical content, and provides a record of basic mathematical expressions and signs in Braille. The paper first presents the theoretical aspects of visual impairment, then deals with the legal framework and rights of blind people, and the way of communication with blind students. The way of communication with the blind is through Braille, using assistive technology and with the help of various mobile applications and web environments that enable the blind to understand the content as well as possible. The paper presents the opinions of mathematics teachers who had the opportunity to work with blind students. Their opinions were recorded based on research conducted in an online environment using Google forms. Along with the teacher’s opinions, the paper describes the basic Braille mathematical notation. Considering that working with blind students is difficult and requires a lot of effort, engagement and work of students, teachers and families, some aids made of wood are described in the paper. Math aids for blind students include aids for better understanding of fractions, the number line, angle and types of angles, triangles, quadrilaterals, polygons, circles and parts of circles, and the rectangular coordinate system in the plane.
