The thesis emphasises the importance of artwork in childeren's education and upbringing as well as the key role of the educator in inspiring children's creativity by means of adequate strategies but also in activities restricting children's creativity. The thesis is devided into a theoretical and practical part. The practical part presents five artistic activities with children group ''Ladybirds'' (5-6 years) and a pre-school group ''Bees'' (6-7 years) in the ''Happy children'' kindergarten in Novi Marof. The activities were inspired by Rabuzin's paintings and aimed to encourage children to draw and paint according to their own impression, reflection, imagination and memory. The children used different techniques and materials which enabled them to express themselves individually and to develop their own skills and abilities. The theoretical part is based on expert literature on children's artistic expression, their developmental stages, the role of the educator and on the importance of artistic work in education and upbringing. The practical part describes artistic activities inspired by the work of Ivan Rabuzin.
