I came across this site today while searching for some free lesson plans "just in case". Thought those of you with littles might enjoy it. It's only for k- 5 but it's seems pretty complete (at least the first grade it). www.lessonpathways.com
I just found this site in my browsing around as well! Before reading this post, I just put the link in the websites section of this site. Good stuff here!
This is amazing!! We just hit a total stalemate with our curriculum and need a little boost this will be an awesome supplement!
