On Mondays, in 5th and 6th grade, I ask them "Did you have a good weekend?", and now they are used to it. They answer with either "Yes, I did." or "No, I didn't" (okay, yes, textbook answers....) and I follow up.
After a few weeks of this, we can now have a very basic conversation that goes something like this:
Did you have a good weekend?
Yes, I did
Why? What did you do?
I went to grandmother house (<-- no possessive 's yet)
I'm going to add on something like "How was it?" and let them answer with "It was ______".
It's the idea of L+1 (language +1), take something that they *can* do, and add something just slightly more to it.
The same concept comes up in 1st grade with fruit flashcards. They all yell "Apple", but I ask "How many?" and "What colour?" until we are all saying "One green apple" or something....
I think the "Finethankyouandyou" as well as the "nicetomeetyou" come from the traditional Korean greetings of Annyeong haseyo and Bangapseumnida, which are, to my knowledge, kind of lacking in the "How's it goin'?" variety of English.
