In the 21st century, raising a child is a big challenge, both for parenting and for professional people such as educators, where it is very necessary to constantly work on educational practice and follow the different interests of each individual child. The term kinesiological activity and its impact on children's health is explained through the final paper entitled ˝The role of educators in conducting physical activities with preschool children˝. The games and activities in early and preschool education institutions, the competencies and professions of educators, and the adequate relationship between parents and educators are also listed. Physical activities should be planned in kindergartens, in and around the house, during children’s free time, either with educators and/or parents. In kindergartens, the implementation of physical activities is exclusively under professional supervision – educators. The educator's knowledge and good preparation for the physical and health education class are very important for their implementation. Through various games, children learn to make decisions independently, participate in discussions and various activities with other children. The paper also mentions the main roles of educators in children's play, which are passive or interested observers and teammates or leaders and controllers of activities. Their role can be changed in such a way as to encourage and direct children's games as well as to engage in play itself. The educator should strive for the role of an intrigued observer with the aim of enriching children's play and various activities in early and preschool age.
