The blind student's interpretation of two-dimensional shapes represent students' mental images of two-dimensional shapes that they can't visualize directly, especially the two-dimensional shapes of real objects that have their own difficulties to be interpreted by the blind students. This is closely related to understanding the concept of geometry of blind students who have lost sight. The objective of this research is to identify the blind student's interpretation of two-dimensional shapes. The result can inspire teachers to design further learning for development of blind student geometry concepts. This research was an exploratory study with qualitative approach. Subjects of this research is a sixth-grade students who experiencing total blind since the fifth grade of elementary school from YPAB Tegalsari Surabaya. Researchers interviewed the subject about his interpretation of two-dimensional shapes according to his thinking. Then, they are asked to compare some two-dimensional models that have been provided by the researcher. Finding of this study denote the uniqueness of blind students who experiencing total blind since since school age.
