Social skills, social skills, social skills! Social skills are taught continuously in my classroom, mainly because we can't seem to go 15 minutes without a learning moment, but also crucial for my autistic students. This year, in particular, I have a very special group of students who require a little extra in this field.
Thursday afternoons I do a full class on one particular social skills subject. Here is one on joining a group I plan to do today. Role play is a must when working on social skills IMO. Get them up out of their chairs and act out scenarios. My kids love doing this.
