ReadWorks is a free service that has cataloged hundreds of lesson plans and nearly two thousand reading non-fiction and fiction passages aligned to Common Core standards. Vocabulary lists and lessons are the latest addition to ReadWorks. Now when you select a passage and a lesson in ReadWorks you can find a list of key vocabulary words to go with the passage. Click on a word in one of the vocabulary lists to find its definition and a list of sample uses of the word. At the bottom of the vocabulary list you will find PDF of practice exercises to give to students.
