Thinking back to how I presented this skill to last year's students, I knew that I needed to do a better job of explaining the Alphonse activity.
I created a slidedeck that helps cue me to keep the activity flowing from the story to considering causes to organizing those causes. There's the intro to the frames at the end of this activity, almost as a pre-teaching of the frames that come in a lesson later this week.
Hope that it's helpful when you teach causation.
