This article, fron theoretical nature, which goal is to discuss the usage of ostensible gestures as teacher's assistants in the process of exposing mathematical proofs to students. Therefore, we discuss some concepts used in math's classes, such as theories and demonstrations' proof, which are susceptible of using ostentatious gestures searching the meaning of mathematical propositions. Our analysis is based on the Ludwig Wittgenstein's philosophy, as well as on some philosophy commentators's of his texts and some mathematic educators who employ it as a philosophical foundation.
