Teacher: All right. You all did four problems, yes?

Students: Yes.

Teacher: Okay. What I want you to do now is, you want to think about the problems you did. You did the four; think about what you were thinking about as you were doing them. You might want to look at your paper–look at the problems you did. Okay. In your brain, pick the two you think are the most similar in your brains.

All right, does everybody have one in their brains, the two? 

Students: Yes. Yeah. All ready.

Teacher: Great. Okay. You’re going to get with a partner. You’re going to tell your partner, “I thought these two were the most similar.” Then your partner is going to guess why you chose those. You’re not going to tell them why you chose the two. You’re just going to tell them which two you chose, and they’re going to guess, “I think you chose those two because…” and then you have to tell them if they’re right or wrong. Okay, does that make sense?

Students: Yes.

Teacher: Is everybody good? All right, let’s go.
