Columbine Teacher's Guide

The Columbine Teacher's Guide is at: http://www.columbine-instructor-guide.com/ 

​

All links from this site should take you there directly now, but if you landed here, I apparently missed an old link. You can also google "Columbine teacher's guide" and it should come up first.

​

And it's free, BTW. Thanks again to all the teachers and profs who helped create it.
