I used these when I first started doing accountable talk work with students in the form of book clubs. Years ago, that with fourth graders. Now, I know that many schools start in the early grades. These tools are great for reluctant talkers, English Language Learners, and any other student who needs a little direction when it comes to group talk.
When I did this whole-class, I would print them out on different colored cardstock for each club, then cutting into individual prompts. I had the students pick which one(s) they were going to use in the conversation. Later, when students got to me with more conversation skills, I would only use them with beginner ELLs and certain students who needed a little push. You can, of course, add whatever prompts to like best.
