Presentation Model vs. Grammar

So far, grammar is winning! 

I am creating lesson plans for Simple, Compound, and Complex sentences for the next four models.  The very first model is Presentation.  Think Lecture.  Think 15 minutes of me talking about sentences.  I'm not really demonstrating, I'm not really looking for student interaction, I'm not always using these sentences correctly in my blogging.

I've sent an email off to my cooperating teacher/instructor/expert inspirer.  I'm pretty sure her background is in math, so she should have plenty of experience taking very specific math rules and turning them into an engaging presentation.  I'm hitting a brain-block on how to talk about subjects and predicates and conjunctions in a Big Picture style. 

I have had some fun on youtube watching various videos of teachers trying to liven up this very subject!  Until they get bogged down in nitty, gritty details and I find myself a bit confused.  And technically, I already know all about the topic!

Phew, grammar, you are important to the world.  But seriously, hard for me to think about!
