By this time of the year, your students are ready to take the reins. Teaching them how to run their own reading group (in any content area) frees you up to pull small groups, check in with certain students, assess students' skills, and so on.
This link will take you to a great resource for roles, instructions, graphic organizers, role cards, question stems, examples, self-reflective feedback forms, and more. You can literally implement this tomorrow. Have fun and get those students working harder than you!
