Practical ideas Ensure that students know exactly what they have to do before they begin any pairwork activity. Run through a few examples with the whole class. For variety, different students can be paired together. Students can be moved around the room or they can be put into pairs with students to their left or right, in front or behind. Give the students a time limit so that they know when they have to finish.
Students can work in pairs to produce questions, exercises, etc. for other pairs to do.
If the task does not actually require pairwork, the students can choose whether they want to work in pairs or alone.
