Artistic expression serves the child as a channel for communication with himself and the environment that surrounds him. Children's artistic creativity ranges from the development of psychomotor skills of hands and fists, the phase of doodling, through the appearance of the first organized forms, spontaneous artistic activity and complex symbols, all the way to intellectual and visual realism. One of the most important goals of art education is to introduce children to the world of art and develop their artistic and creative abilities. In order to achieve this goal, it is essential that educators are committed to creating a safe, comfortable, stimulating and multimedia environment in which children can explore, discover and create without hindrance. Various art techniques are used in the educational process, including spatial-plastic design techniques. In this paper, the emphasis will be on the sculptural technique of clay. Clay is a material that is very interesting to children due to its characteristics such as softness, pliability, elasticity and plasticity, but also the process of working with it. Clay modeling allows children to completely reshape, subtract and upgrade the modeled work. From kneading, folding, bending, tearing, squeezing, that is getting to know clay, from basic to more complex shapes, all the way to more realistic visual features of shapes, we follow the development of children's artistic expression like the development of their artistic expression in drawing. I spent the practical part of the work at the „Milan Sachs“ kindergarten with children ranging in age from 2 to 6 years.
