I dig the idea of a virtual filing cabinet--a place where people file away e-resources for personal use but available to all. Instead of filing away every resource I can possibly find on a topic I want to post what I actually use (or plan to use) in my courses.
I started this past summer with my Algebra 1 and Algebra 2 courses. Slow and steady the resources come online. I've already gotten quite a bit of my linear stuff up. Next week we break into quadratics and then to exponential functions, polynomials, rational functions, etc.
Take a gander. Check back in a month or so for new stuff. If you feel like adding some suggestions, please give a holler. I'd love to use them.
