These sentence starters should get students talking! I actually cut them onto strips and hand each pair of students an envelope with all the sentences in there. I find that making them into a simple manipulative (and setting it up so that students only need to look at 1 sentence at a time) makes the task somehow less daunting and more engaging for students.
I ask students to complete as many of the sentences as they can in 10 minutes. I circulate and try to push students to improve their answers.
