Language communication inherent is exclusively human. How important it is to show the fact that it is almost impossible to distinguish a segment of human life and action in which speech and language are not represented and important. Neatly developed language and speech are important for the entire child's development, for its successful education and professional commitment, and later for professional advancement. It is therefore important from earliest time to encourage children's speech development. Apart from parents and families, children's educational institutions and, of course, selfeducators play an important role in this process. Numerous didactic materials and worksheets are also available to help them stimulate children's language-language development. The subject of the research of this graduate thesis is just kindergarten workbooks - working papers and their application in the language development of children. A comparative analysis of pedagogical activities was carried out using selected work materials and described how children were accepted and used by children. the research is to explain the correlation of working papers with the development of speech in pre-school children. It was thus assumed that no significant qualitative difference between different kindergartens (work sheets) would be established to encourage the linguistic development of preschool children. The paper is divided into two parts: theoretical and exploratory. In the theoretical part of the paper, the area of research carried out - the child's linguistic-language development - and the educational context in which this development is promoted by appropriate methods is presented. In the research part of the paper, qualitative approaches analyzed work materials to stimulate children's speech-language development and their usability in working with children of preschool age.
