Are you in need of a website to help you build reading comprehension in your K-8 students? Readwork.org is a great place to start!
ReadWorks provides research-based units, lessons, and authentic, leveled non-fiction and literary passages directly to educators online, for free, to be shared broadly.
The ReadWorks curriculum is aligned to the Common Core State Standards and the standards of all 50 states. Most importantly, ReadWorks is faithful to the most effective research-proven instructional practices in reading comprehension.
I was very excited to see the long list of novels featured on the site. Each novel unit is complete with lesson plans, materials, and standards alignment. Another strong feature of the site is giving a lexile level for all readings and activities. Additionally, the searchable database of reading passages span all circular levels. I can see teachers using the site to supplement Science and Social Studies with readings that are also addressing reading comprehension.
Readworks is supported by major foundations so currently the site is free to use. If you are an elementary or middle school teacher this site is definitely worth a look!
