The introduction is a four hint quiz game.
Students make groups and listen to the hints then see the picture. One member should come with their guess. It is is correct let them pick a letter and get points for their group. After every team has come or after time is up do an answer check with everyone.
There are four questions.
Then either in groups, pairs or on their own they make their own quizes.
Ideally these quizes should be presented to the class.
