The Croatian language includes three dialects - štokavian, kajkavian and čakavian. In this paper, the topic is the kajkavian dialect, the Podravina subdialect and the Gola speech, as well as the presentation of that speech to preschool children. When the child participates in circumstances where dialectal and standard language intertwines a multi-idiomatic language environment is created. Namely, the child of an early age adopts the language of the environment as his first speech, most often dialectal, and by going to an educational institution it also adopts the standard Croatian language. The importance of introducing children to the richness of the Croatian language is confirmed by the principles of basic documents for determining the practice of early and preschool education, Strategy of Education, Science and Technology (2014) and the National Curriculum for Early and Preschool Education (2014). By getting to know the dialectal diversity of the Croatian language, children gain knowledge about the world in which they live, but also metalinguistic awareness - awareness of language as a means of communication and the various manifestations of that means, awareness of the connection between language and space and language and culture. Knowledge of the world, as well as metalinguistic awareness, will be valuable to the child in learning and the tasks that its future education and life will present to it. There are many opportunities to present Croatian linguistic diversity to children of early and preschool age, and one of them is a project as a way of learning based on asking questions, looking for answers and solving problems and requires coordinated activity of people involved. This paper describes project activities in the Podravina subdialect (Gola speech) in two kindergartens, in Varaždin and Virovitica. About forty children participated in the activities. The course of project activities is presented, and from the analysis of the results we can conclude that most of the children from Virovitica did not have the opportunity to meet the Podravina subdialect until then. Children from the Varaždin kindergarten, the Podravina subdialect was much closer. They understood most of the dialect words and communication in general, but also noticed the differences between the kajkavian Varaždin speech and the kajkavian Gola speech. In conclusion, it was shown in both groups of children that the implemented activities significantly enriched their knowledge and experience, and especially made them aware of the linguistic differences and dialectal richness of the Croatian language. This topic - Croatian dialect diversity - is less present in kindergartens, and it is an important part of children's socialization and children's knowledge about the world in which they live. This paper is a contribution to its affirmation in institutions for early and preschool education.
