An information gap for a pair of students (duo), based on the Present Perfect Simple usage of an experience at some time in the past. The basis is “Have you ever + pp ?” Students are first asked to create their own ‘Have you ever …’ questions. They are assigned a partner, and try to predict their partner’s answers to the questions. Then they ask their partners the questions and see if their predictions are correct. Some students will ask very mundane questions, and others ask totally crazy questions, but it’s all good language practice.
This information gap activity is for elementary to intermediate students and will take about 30/40 minutes.

Good point, thank you.
Plus I feel that when students generate their own questions they are more interested in their partner’s answers.
Thank you for this.. easy to use and it allows the students to generate their own vocabulary.
