The aim of this paper is to illustrate the characteristics of the play of a child with autism spectrum disorder within an educational institution. The paper explains the concept of play, the importance of play in a child's life, the concept of autism in a broader sense, as well as indicators for the recognition of autism. Particular attention was paid to the depiction of play by children with autism spectrum disorder, the difficulties they encounter during play, and the role of educators in mastering these activities. The paper describes pedagogical procedures and participation in the structure of play in working with children with autism spectrum disorder. The methodological part of the paper uses a case study and an observational method. The research subject for this paper is the analysis of the play characteristics of children with autism spectrum disorder, and the research aims to describe the mentioned characteristics of their play. The characteristics of the observed play pattern are observed within the educational institution, more precisely primary school, and the knowledge gained is recorded and then analyzed and interpreted. Research questions on the behaviour of a child with autism spectrum disorder during play, along with the involvement of other people in the play, are answered in the interpretation and discussion part of the paper. Qualitative results are presented, showing that the observed pattern for its play selects very atypical material objects, whose meaning is determined during the play. Stereotypical dancing behaviours are present, most commonly involving nose squinting, hand clapping, and wrist twisting. The case study determined that the observed pattern matches the play objects according to a certain pattern, which reflects a need for perfectionism. Qualitative results showed that individuals with autism spectrum disorder predominantly play alone and rarely engage in group activities. When playing with other pupils they often do not follow the rules of the play and need to be warned repeatedly to make them aware of their violation.
