This is a great site for language arts writing resouces. It's based on the 6 + 1 Traits of writing. There are interactive lesson plans, interactive writing prompts, student samples which help struggling writers with the brainstorming and organizing writing at many different levels. This website is FANTASTIC! I've used it a number of times with my 1st Graders!!

Offers lesson plans, printables, computer bases labs for students, whiteboard integration activities, even a teacher to teacher blog. The primary focus is on language arts curriculum for grades pre K-5. The teacher share section is similar to diigo!
