The need for artistic expression in children of early and preschool age arises naturally. One of the sculpting techniques that allows children to express themselves artistically is clay. Molding with clay has been present since the earliest civilizations, which made various functional and artistic objects from this material. This paper aims to emphasize the importance and benefits of modeling with clay when working with children of early and preschool age. Encouraging a child's overall development is of great importance, and it is, among other things, influenced by the child's subjective well-being and sensorimotor development, on which clay has a positive influence. In addition to being an art medium, clay is also used as an expressive medium for therapeutic purposes. Its flexible structure enables rich tactile experiences that help strengthen the connection between the child's senses and feelings. This paper describes the properties of clay and how to prepare it to be suitable for working with children. Clay can be modeled in various ways. It is important to emphasize that with children of early and preschool age, we distinguish the stages of clay molding depending on age and how children approach it. In the entire process of artistic expression, the role of the teacher, who thoughtfully plans and creates a safe and stimulating learning environment, is crucial. The educator's interventions should be occasional and stimulating, his approach individualized, and his communication with the children two-way. The paper presents and describes three art activities with clay conducted in the Grigor Vitez kindergarten in Zagreb.
