Children's artistic expression represents one of the innate abilities of expression. Children consider artistic expression as a game and are spontaneously encouraged to express themselves in this way. The development of children's artistic abilities helps in the development of their complete personality in the cognitive, psychomotor and affective areas. Art education plays a very important role in introducing children to the world of art. Children create based on their own experience, observation and imagination. Educators and the kindergarten as a whole should provide the child with an offer of materials that is varied and interesting, and therefore stimulating. The educator thinks about the children's art education, implements and plans it. The design of art activities should follow the developmental possibilities of children, their interests and needs, and the incentives must be unstructured and problematic. The role of the educator is to monitor the children's artistic development, on the basis of which further directed artistic activities and individual development of children in the field of art are planned. One of the art areas in which preschool children express themselves is sculpting, which we say is a type of artistic expression with three-dimensional shapes and bodies. The product of sculpture are sculptures that are artistically shaped in space. By modeling and building, children develop their motor skills, get to know different sculpting techniques and materials. Clay is a malleable material, so its soft and plastic character enables a variety of processing. By kneading and pressing, children can model hollowed and protruding mass, flattened mass, by drawing out they can get cylindrical shapes, and by pressing they can create hollow ones. Due to its adaptability, clay will encourage the child to experiment and examine its possibilities. By noticing changes in the clay, children learn that their actions have consequences, which affects the shaping of their personality, but also empowers them. The aim of this work is to investigate how children of early and preschool age express themselves by modeling with clay. The research was conducted with practical art activities of children in three educational groups.
