This work material is designed to teach autistic children about the importance of saying goodbye in social interactions. It contains information on how and why we should say goodbye, practical advice, and interactive activities to help children understand and practice this skill. Furthermore, it presents scenarios in which one should say goodbye, promoting reflection and reasoning. Coloring activities and reflection questions complement the learning, encouraging children to explore their emotions and others’ reactions in different situations. With this material, autistic children can develop a better understanding of social interactions and strengthen their communication skills.
