I have been searching all over the Internet looking for great resources for teachers to use to find an article to use in their classroom. I do at least one close reading with an article each week in my class. Here are the sites I use to find the articles:

• Read Works: ReadWorks provides research-based units, lessons, and authentic, leveled non-fiction and literary passages directly to educators online, for free! K-8
• Vale Middle School: This site has articles and questions for Lexile level 900 and up. Free 
• Kelly Gallagher:  This site has articles and questions. The articles are assigned to high school students, but many could be used for middle school too. Free
• Teaching the Core: This site has excellent articles for middle schoolers. Free
