As an elementary teacher I find this site to be an excellent resource. Some sites that I go to say they have lesson plans but they are very brief and don\'t contain any supporting materials and are virtually useless. Not so with Read-Write-Think lesson plans. They are written by practicing teachers, outline all materials required, give detailed instructions with estimated time frames, and have links to supporting resources and/or downloadable pdf\'s. The lessons are searchable by grade level making it easy to find lessons that will work with my students.
