Chess Curriculum K-12

I'm a volunteer coach for a K-5 chess club, though just a beginner myself. I think that after a few months of playing chess 2X a week, you can push the K-6 kids a little more. I gave out puzzles last week with 2 and 3 move combinations and was surprised at how many kids were able to solve them. I'm starting to think there are four or five kids that might even be ready to develop a basic opening repertoire. Like I said, I'm a newb at this, so take my opinion for what it's worth.
I want to start a chess program in the school that will coach kids from their first days in Elementary school all the way through graduation day. I'll post the extremely basic curriculum below, and would really appreciate any suggestions/comments

This is just a rough idea of what the curriculum would entail. Setting aside issues such as funding and getting it into the schools, what are your thoughts as far as the material itself goes?
