That cake analogy had to come from her. She uses it in her workshops, and we used it to bring the info back to our teachers.
Show the kids a plain cake, and explain that this is like a beginning, middle, end. It's complete, but it could be somuch better!
The frosting, sprinkles, fruit, etc. (whatever you add) are like the grabber, zinger, and other creative aspects (vivid verbs, hyprebole, etc.)
Her book Writing Superstars has mini-lessons for all of these things, I highly suggest it.
