I think the intent was to get you to understand sentence composition better and to be clear about which part of a sentence a given word might be modifying (i.e. adjective versus adverb, etc.) but somehow I never got that out of it at all. It just wasn't a particularly effective learning tool in that regard.

I guess some kids get the stuff conceptually very fast (I was one) and some don't and need other ways to get it in their heads and (I'm guessing) this is just one more way to present the concept so some kids will "get it".

Having to present and re-present the same concepts over and over five or six different ways so that every kid in the class "gets it" is tedious but probably necessary, especially in bigger and bigger classrooms. The counterpoint is it's frustrating to see so much needless repetition in the classroom and the consequence is that everyone gets held back by the ones that need to see the stuff from so many different angles in order to grasp it. The politically incorrect (but honest) term for this is "dumbing down".
