The topic of this thesis is "The impact of traditional creativity on the development in children", which I chose because it is an area in which I actively base my immediate educational work. I believe that traditional creativity can be "richly" permeated through all educational areas and influence the development in all of children's competencies. Children are naturally curious beings and are interested in everything that is unknown to them, and that is presented to them and offered in an appropriate and interesting way. In order for a child to adopt the foundations of their cultural heritage, he or she must have co-workers, parents, educators who will encourage children's curiosity, creativity, attitudes and thinking. Immediately after the birth of a child, play becomes the only means of communication with people and the environment in which he lives. Children love to play through movement, song. They love games with singing, counting and are interested in the cultural heritage of our ancestors if it is presented to them in a certain way. Children's folklore has all the essential elements of traditional heritage. In addition to the folklore songs and dances, children through folklore meet children's traditional toys and instruments made of materials from nature, various customs, children's games and clothes and shoes from the past. Folklore elements are all contents that are connected with the national heritage and tradition. They are connected through many contents from music, dance, art, writing, traditional and indigenous, instruments, folk costumes and tools that were used in a certain period. They were transmitted by written record, but in most cases, it was an oral tradition from generation to generation. The main prerequisite for successful work with children is knowledge of the appropriate and authentic choice of materials and knowledge of the methodology of work. Literature in the field of children's folklore is very scarce. The greatest contribution to Traditional Creativity in our area was made by Goran Knežević, the first children's folklore pedagogue and choreographer in Croatia. Author of numerous ethnological literatures on children's traditional creativity, as well as the leader of seminars that I regularly attended. In my work I have mostly used his literature, and in direct work with children I often use its contents and work methodology. As a result of traditional creativity in working with children, in addition to cultural creativity, we indirectly influence the development of human values, encourage children to community and mutual cooperation, good mood and cheerful atmosphere that results in a positive image of themselves and others, and excellent cohesion of the group. affects their socio-emotional growth and development, which is the foundation of further growth and development of children.
