Work in groups of four students
Have you ever visited a WHL site?
Were you aware of this? How?
Discuss about sites that you suppose are in the World Heritage List.
Then check, by using the official site, if they are included.
Make sure you are using the right name (maybe a site can be associated to a larger monumental setting).
In each group, a secretary has to create a file listing all the sites visited by the members of the group (if many students visited the same site, repeat the item).
You can create a tag cloud expressing the popularity ranking. You can use a free tool as this one
or you can make charts expressing the most popular sites in Italy, Europe, extra European continents.
