Repeated Conversation

From today, with groups of students handing in a group work assignment:
Me: This problem asked you to show that these numbers are composite. You only listed them.

Student: But they are composite!

Me: But you haven't shown this. You just listed the numbers.

Student: But it's right--they are composite!

Me: How could you show the numbers are composite?

Student: I don't know. What's a composite number?
Repeat for most groups.
