Tell them you want to go on vacation somewhere in Korea and need their advice.
"Where should I go?"
Collect some answers. I usually choose Jeju Island, for reasons you'll see later.
"Should I go in summer?" Yes, no, etc.
"So what can I do there?" Blah, blah.
"How can I get there?" Airplane? "Can I swim?" Hahaha! Crazy teacher. No, you can't.
Elicit some answers and have a bit of fun with it. Write up on the board/PPT:
Where should I go?/ Should I.....?
What can I do there? Can I....?
and you're good to go!
