If your students struggle with participating in student-centered discussions, these task cards are for you! These cards can be used in any text-based discussion. I suggest laminating a set of these cards and distributing whenever you are having a class discussion. These cards serve as scaffolding for students less likely to participate and as an extension for students who need a new challenge.
This set includes several roles including: ask questions, post ideas, revoice, play devil's advocate, and press other's for more information.
