Write down the names of 3 members of your family
(cousins, uncles, grandmothers whatever).
Pair up with somebody, look at your partners list and ask each other the following questions...
How old is she/he?
What does she/he like?
Can you describe her/him
Continue asking questions if it's interesting or move to the next.
Could also be done as a whole class, teacher writing names up on the board as we go and students asking questions with hands raised of course.
More complex questions that could be used.
What does she/he look like?
What's she/he like?
Do you get on with...?
How do you stay in touch with...?
Does she/he have any bad habits?
