Introduction. Results presented in this article are part of an international project called Project of physical activity stimulation in a family (PPASF) held jointly with the Klaipėda University and LASE in Riga. We decided to check whether participation of children in preschool age in active classes in nursery school may be an impetus to change behavior in terms of physical activity of a family. For this purpose, a model was developed that included physical activity program conducted in the nursery school, with homework for the children to do together with their parents at home. The aim of the study was to examine the extent to which a child can persuade the parents to a common physical activity and whether sport and recreation for children with homework are a successful proposal to increase motor activity of the family. Material and methods. A diagnostic survey method was applied in the research, using a questionnaire technique. The survey questionnaire covered 38 families including 30 mothers and 8 fathers. Results and conclusions. Research has shown that children can become facilitators of physical activity in the family. The proposed model classes for children proved to be an accurate proposal, which is worth to implement the practice of teaching.
