The purpose of this final paper is a theoretical presentation of knowledge about the development and developmental environment of the child, which is based on the development of listening and language skills of preschool children. The child should be provided with adequate conditions and environment for development, which includes the spatial and material environment of the family, the social environment of the family, the spatial, the material and the social environment of the kindergarten. Educators themselves play a vital role in a child's development of communication, language, and hearing abilities. Conversation as a skill is not acquired by birth itself, but it is upgraded through life, conversation is learned and actively enriched by practicing it in the environment of other people. In order to learn to talk and speak, we must first hear and listen. In order to listen, we must make a conscious effort not only to hear what people are saying, but to take it in, process it, and understand it. Listening develops language and communication skills; that process is very important in preschool children who are placed in a new spatial-material-social environment called kindergarten.
