This thesis deals with the Croatian dialect heritage, more precisely raises awareness of the importance of language. It also attaches importance to the acceptance of all Croatian dialects as the core determinants of the Croatian language and as a national linguistic wealth. The paper consists of five parts. In the first part of the paper are shown basic data on Croatian languge and dialects. Furthermore, shows characteristics of each of the three Croatian dialects: “čakavsko”, “kajkavsko” and “štokavsko”. In addition, we can see where each dialect is spoken in Croatia and places where croatian speakers live. Some of the literary authors who wrote or are writing in that dialect are also mentioned for each dialect. The second part opens the topic of children's language acquisition, the development of children's speech in a multi-idiomatic environment in which the dialect is used, but also the standard Croatian language, and in many other languages. Accordingly, the importance of a stimulating environment for the development of children's speech is emphasized, which should be provided to the child by parents in the immediate and extended family and educators in institutions for early education. The paper also mentions concrete ways, various activities of language expression, which could encourage children's speech and communication development. he third part emphasizes the value of national identity, and most of the data are based on the document of the National Curriculum for Early and Preschool Education (2014). According to this document, the preschool period is seen as a key period for the development of a child's identity. Among the activities that encourage children's language education, traditional games stand out as those in which the linguistic, cultural and identity component is united, but they are unfortunately less and less present in children's play. In the last section of the fourth part, a list of games that used to be played is brought, and today they are getting closer to complete oblivion. The fourth part is the core of this thesis because it provides specific information about the possibilities of including Croatian dialect heritage in working with children in kindergarten. The activities carried out, their results and children's reactions are described.
