Narration help

I’m homeschooling my two younger daughters after having homeschooled my sons through high school.  You would think I’d have this all figured out by now but I don’t!  🙂  I don’t feel confident at all with narration.  I used IEW with my boys but my current 5th grader really, really doesn’t like it.  My question is how do I know what to ask in a narration to get my daughter to write expository essay, narratives, etc?  I have the SCM books on narration but I just don’t feel confident in my own abilities to use narration for composition.  How do I take a few lines from my daughter and turn that into 5 paragraph essays later at high school levels?  IEW was so formatted I didn’t need to think about how to teach it at all.  It was all right there.  Help!                                                                                                                                                                               Thanks!
