Though this isn't a state specific site, it's very easy to navigate to find links for most SLEs. If you don't find what you need, be sure to search a few grade levels above and below as there are more resources there. There's also a search option at the bottom.
Don't forget to see if Brain Pop has a video that matches the SLE. I recommend printing the quiz and allowing the kids to comlete it before, during, and after viewing.
