GETTING QUESTIONS FROM YOUR STUDENTS
"I don't know."
Good for the one off question just to make a point and ensure that the student is with you and capable of making minimal manipulations of the material in hand.
T What kind of car do I have?
S I don't know!
S What kind of car do you have?
T I have a Ferrari.
or at a more advanced level:
T How long did it take me to get used to
driving on the right?
S Maybe a few weeks?
T Well, ask me?
S How long did you take ....
T (interrupting) How long did IT.... .
Here the student has slipped into a common mistake. The teacher puts him back on track but leaves the student to finish the question.
