This is a very easy worksheet which can be used in several ways. I usually give a copy of the worksheet to each student (if the level is low, a translation session will be of help), then I let them cut out the cards and pick the ones they have actually experienced. Then I let them walk around and when I say 'stop', they interview the nearest classmate by taking notes. The aim is to find out which friend is the one they share the most with. This goes for several times, until we go through their survey.
