Here are a few examples:
-Inferring characters emotions and thoughts
-Grammar & spelling
-Articulation (have your students read his/her story out loud!)
And those are just skills my students are working on. I'm sure you can find more uses for this activity. This is a fun activity that may put a new spin on old goals that you have been working on for months. One of the best parts, this can easily be done during 30 minute therapy sessions. Use one session to watch the videos and take notes and the next to write the summary and edit the writing.
