The practical experience of drawing in the Speech-Language Pathology clinical practice is taken as the central and generating nucleus of the present study. It is investigated the dialogical practices that trigger processes of knowledge construction able to relate drawing to the appropriation of senses and meanings, which could affect the deaf children's language development. From the point of view of a qualitative analysis, the study used theoretical and methodological constructs stemming from a Historic-Cultural perspective. The subjects of this case report were two bilingual male deaf children with ages between nine and ten years, both with profound bilateral hearing loss and complaints of delay in their language development. Data were gathered for a year, producing 30 hours of video recordings and reports regarding the 60-minutes weekly therapy sessions that were carried out during this period. Taking children's, language's and drawing's development as a constantly-changing process, the focus of the analyses was the emergence of actions-in-change and the dynamics of the interactions between the studied subjects. Results showed that the priority given to the use of sign language associated with the therapeutic focus on signic activities, which took into account linguistic particularities and semiotic mediations, were vital for language acquisition and development to favor deaf children's social practices.
