BAROJAS GOMEZ, Andrea  y  GARNICA DOVALA, Ignacio. Comprehension of notions of the decimal metric system measured by the LSM in classroom of deaf [17-21]: case study. Relime [online]. 2017, vol.20, n.3, pp.317-344. ISSN 2007-6819.  https://doi.org/10.12802/relime.17.2033.

A central problem of the teaching of the mathematics of the Deaf is communication between teacher and student, a situation that requires the recognition of the Languages of Signs as naturals. Our research starts from this principle and is oriented to the understanding of the Mexican Sign Language (LSM) in its relation mathematical notions that are developed in the classroom of Deaf, specifically to the one of its grammar and to the construction of Signs related to notions of the decimal metric system (DMS). A communication model is proposed to develop three processes in the classroom: teaching, research and inquiry that led to the construction of Signs pertinent to each of nine notions: seven of mathematics and two of instruments of measurement. It was performed in real-time conditions in the classroom with eight young Deaf people. The results show the relevance of the above described recognition and the necessary presence of the written language.
