Great activity for teaching Social Thinking's Unexpected behaviors and delving deeper into how unexpected behaviors make others feel. This lesson is engaging because it uses movie clips on YouTube to show examples. Worksheet can be completed by students or a framework for discussion. Links can be cut and pasted into your browser to access the clips.
*The video clips are public clips I found on YouTube. If they are no longer available (as I have no control over the accessibility to them) you can do a quick search to find something similar.
