Student: I already know the answers to these. Should I work them out anyway?
Student: I already know what the answer will be. I can see it.
Teacher: Well, work them out anyway. I'll check them when you're done.
Student: You mean I should show my work?
Teacher: That's right. You get a half point for the right answer, and a half point for the right method.
Learner: I already know the answers to these. Should I work them out?
Learner: I already know what the answer will be. I can see it.

Facilitator: Show it to who?
