Educational programs for engineering disciplines for children from 4 to 6 years old are based on a clearly defined system of training and teaching using special educational kits and digital tools. Education starts from 4 years and in 2 years children develop more and more skills that will be useful to them in the future. In addition to developing self-confidence, communication skills and teamwork, students learn the basics of mechanics on interesting models that are understandable to their age, and thus engineering disciplines, mathematical calculations, the basics of project thinking, and focus on the lesson become understandable for children. Question of the child: "Why should I sit quietly in the lesson?" disappears by itself. It is so interesting for children to assemble a moving motorized model that love for exact sciences is instilled in itself, non-standard technical thinking develops, and understanding of the importance of the learning process arises. Naturally, such a skill is also transferred to the study of other school disciplines, and to the life view of the importance of self-development. The number of children in the lesson is limited - 6 people in a group. Each one works individually on his own model. The task in the lesson is not only to assemble a beautiful model, but to understand how the mechanism works, what basic components are used, how parts are correctly named, and explained using competent technical terminology.
