I made a few changes to my rule list, mostly to do with formatting. If you are a punctuation expert, you'll notice I left out anything to do with reduced clauses. For example, I think it would be very difficult for fourth graders, who are still struggling with parts of speech and what makes a complete sentence, to understand the following types of structures.
After they hit pay dirt, miners would stake a claim by piling up rocks in four corners.

I also think that the understanding of when a comma precedes an adverbial clause that follows an independent clause is too confusing. I have to really think about those myself, and it's not really essential to understanding sentence structure. Hence, I left that out.
I'm now formatting my Gold Rush examples in Power Point and will have them up, along with a photo of what the finished product can look like in a classroom, shortly.
