OK, I have an English degree and I like sentence diagramming.
BUT, I liken it to proofs in geometry. What is the point???
I have forced (yes, it was like that) my oldest son, 14, to do some diagramming with his R&S Book 7 text, but he doesn’t like it. I have done it b/c I felt like his understanding of sentence structure and even some basic parts of speech was very lacking.
However, I don’t make him do a lot of sentences and the ones he does, we correct as needed together. Otherwise, I know he isn’t getting anything out of it.
I say a little goes a long way on the diagramming, and if your child is a natural writer they probably don’t need any of it.
Isn’t AG full of diagramming? I remember watching one of the videos and thinking it was going to be way too much for our lking. But maybe I’m thinking of something else?
