ReadWorks is a free website offering resources for differentiated reading instruction, specifically comprehension. There's a range of nonfiction texts, activities, and assessments as well as an online platform teachers can use to track student progress. Teachers can add students manually or via Google Classroom by sharing a class code. Teachers can easily assign passages, corresponding vocabulary lists, and Common Core-aligned question sets to an entire class or to individual students. An easy-to-use Assignments dashboard makes it simple to grade student responses, track progress, and provide direct feedback. Multiple-choice questions are automatically graded, but teachers will have to grade short-answer questions and, if they wish, provide written feedback
