Readers' Theater, Recycled Writing, and the Common Core Standards

Last October, I reintroduced scary readers' theater to my fourth, fifth, and sixth grade students.  Year after year, the kids consistently enjoy and request it.  This year's crop of sixth graders, however, really has run with it.  I've always suggested, as a followup to using professionally-authored scripts, that students can write their own scripts, but no group has ever taken me up on it.  Students from this group already have produced, outside of class time, four of their own scripts, one of which we've performed.  They continue to submit scripts for my consideration.

I'm extremely gratified that our sixth graders, increasingly concerned as they are with their social status among their peers, feel such enthusiasm about writing and even accept editing of same!  I have no complaints, but I have two concerns.  First, they seem stuck on the plot of preteens trespassing on forbidden wooded property where they come to no good end.  And, second, while I justified using readers' theater as a means for students to compare / contrast the experiences of reading versus listening to literature (a Common Core Standard), I have many other standards still to address this school year.  My challenge: To get us all unstuck without stifling enthusiasm.  Any suggestions?
