"Before we jump in, can you tell me the main idea, or the 'gist,' of your favorite movie? What's it mostly about in just one sentence?"
Teacher Tip: Listen to the student's response. Guide them to a concise summary if they get bogged down in small details. Praise their ability to summarize the "big picture."
