This 3-worksheet and domino game activity represent a whole, 90-minute class with university age students in mind.
The first decide which questions are personal and then learn i) how to ask them tentatively ii) how to respond.
Finally a domino game help them practice. Depending on class size, teachers can cut up the dominoes before class - this will avoid wasting class time and mistakes students may make in cutting the dominoes the wrong way.
If there's time, the first worksheet can be used as a whole-class activity where students ask and answer (or refuse to answer).
