Like the impact of natural language on normal children, sign language plays an important role in the comprehensive development of deaf children. Deaf children also use sign language to think, communicate and socialize. So how do we teach deaf children sign language? Is teaching sign language to deaf children the same as teaching language for normal children? In this article, considering the situation of many deaf children in the first grade who have few language skills and limited communicative competence, we discuss the factors affecting language teaching in these environments. Furthermore, we propose games which may enhance their language skills, and to assist them to develop and improve the quality of life, and thus to integrate into larger society.
