The purpose of this study was to investigate the effect of job checklist production activities based on the Blue Marble game board on side dish packaging and delivery job skills of adults with intellectual disabilities. Participants in the study were three adults with intellectual disabilities living at home without employment after graduating from a special school for intellectual disabilities. The research design was composed of a multiple probe design across participants in a single subject research, and the learning room in the group home and the side dish specialized business were composed of an experimental environment. The independent variable was made into a Blue Marble game board based on the number of side dishes, names, and images of delivery apartments, and in connection with this, a virtual demonstration procedure was organized in which participants delivered directly to the apartment. The dependent variable consisted of a tasks in which participants packaged side dishes directly from a side dish specialty business and delivered them to apartments in the area. As a result of the study, participants effectively acquired and generalized side dish packaging and delivery job skills through intervention activities. Through this, it was possible to conclude significant functional consistency between the intervention activity and the dependent variable.
