According to Common Sense Education: "CommonLit's adaptive reading toolbar makes text accessible for students at a variety of reading levels and language abilities. It's perfect for English language learners and struggling readers. Every passage -- printed in PDF format or accessed online -- includes footnotes with vocabulary words and essential background information that is critical for kids to understand when reading a passage. The included discussion questions get students thinking critically about text during independent reading and beyond. Thinking about reading is further encouraged by text-dependent questions that are included with each passage."
