SBG list for Common Core Algebra 1

I am thinking carefully about which standards to use for SBG in our new CCSS Algebra 1 curriculum.  The semester 1 book I wrote incorporated all of the concepts that our department wants to use in the order we will be using them.  The question though, I think it's a very important one, is exactly which concepts do I deem "Standards Worthy"?  I searched around on Dan Meyer's blog and found that he had featured a post by Mathy McMatherson that does a great job of explaining how important they think this question is.  If anyone reading this has any input on which standards they grade in a  SBG 9th grade CC Algebra 1 course, I would love to hear from you.
