During this video the students were analyzing and identifying a compound sentence.  I first learned about analyzing sentences in this manner when I listened to Michael Clay Thompson at a seminar.  I was fascinated.  The students are really able to make better sense of how this all works together when they see all the pieces in action.  Every sentence is new, but the structures become recognizable … as do the subjects and predicates … and all of the rest of it.  I compare it to listening to an orchestra and talking about the role of the various instruments and how they complement each other…. and all while the orchestra is playing.  We are listening and making sense of it at the same time.
