Clay has been modeled and used from prehistory. Ceramic pieces have had different purposes, but in this work, we will be focusing on the process of modeling clay. The topic under the name “Modeling clay in art classes” establishes the importance and the positive aspects of modeling clay in art classes. In this work, it is talked about the children’s artistic expression and the need of it that comes naturally to them. Steps of the modeling process and guidelines for safe using of clay are elaborated with the aim to familiarize it to the teachers. In this work, it can be seen how, with some adjustments, it is possible to organize a class where students can work with clay, even if the conditions are not ideal. A teacher has an important role in the students’ lives and he influences students’ creativity and independence. Showing and analyzing reproductions and works of art is an important part of the process. Some meaningful art pieces from different cultures and times are mentioned, which are important for inspiring children in their own work. Children who are interested to know and do more, can go to extracurricular activities and learn more different techniques and processes of making ceramics. Clay modeling has an important role for the child’s psychomotor development, which is important for writing development. There has been some research on children’s expression and development of motor skills. Those studies showed progress in children’s expressions with age and that more and more children have fine motor disorders and disorders with eye-hand coordination. The aim of this paper is to encourage teachers to use clay in their classrooms more and to show the positive aspects modeling has on children and their development.
