Three-dimensional modeling with various materials is extremely useful for the development of children at an early age, encouraging their creativity, concentration and fine motor skills. Shapes such as a stick - a roller, a tile, a ball are basic symbols in children's artistic threedimensional expression. They are as significant as the basic symbols in a drawing (Belamarić, 1986). Clay and/or similar elements are shaped in various ways, by kneading, bending, deepening, subtracting from mass and adding mass (Šošić, 2019). This paper shows the three-dimensional shaping of children of an early age who are enabled to play with volume, texture and forms in order to create a work of art that is experienced from all sides, and not only as a flat surface, which is the case with two-dimensional works. Threedimensional design refers to the creation of works of art that have depth and spatial presence, as opposed to two-dimensional ones that are flat. In this paper, an empirical part was conducted, which investigates the way and meaning of researching children's works of early age children with different spatially plastic materials. The described research was carried out in Kindergarten Karlovac, in 2023, in which 19 children aged 1.5 to 3 years, from a nursery school group, participated. Through the analysis of 39 children's works of art, an attempt was made to gain an insight into whether children of an early age form relief, volume, and whether they intentionally combine colors during threedimensional modeling. A qualitative approach was used in the research. The results showed that children of an early age shape sculptures and reliefs in three-dimensional design, as well as intentionally use a certain color in the representation of sculptures and reliefs.
