This paper focuses on emotional intelligence, considered both generally, as well as in the context of pre-school children. The activities are in accordance with the literature and were carried out in the educational group of the “Izvor” kindergarten in Samobor on 12 September 2017. 20 children of different ages participated in the activities, which proved to provide the ideal circumstances when observing different emotional reactions given the fact that emotional intelligence greatly depends on the experiences of individuals. In addition to the activities described in the final chapter, the paper is based on theories, models and manners of measuring emotional intelligence. The chapter entitled “Development of emotional intelligence in a child” explains in greater detail how parents and/or educators may participate in the development of emotional intelligence skills in a child in order to raise children with a high level of social and emotional intelligence.
