ReadWorks is a free service that I have been recommending for about a year now. It provides teachers with hundreds of lesson plans and more than two thousand reading non-fiction and fiction passages aligned to Common Core standards. Recently, ReadWorks expanded again. The latest expansion includes poems and question sets. The collection is organized by grade level. In the collection you will find poems by Frost, Dickinson, Stevenson, and other notable poets.

Applications for Education
One of the aspects of ReadWorks that I like is that lexile scores are listed for each article along with grade levels and Common Core standards. So if Common Core standards are not relevant to your situation, ReadWorks still makes it easy to find fiction and non-fiction articles that are appropriate for your students.

With a free ReadWorks account you can search for lessons and reading passages by grade level, lexile score, reading skill, subject area, and text type (fiction or non-fiction). In your ReadWorks account you can create digital binders of the lesson plans and reading passages that you want to use.
