The "Talking wall"

Have the students face each other, in pairs.They can be standing or seated.
(They were seated in my class.) The idea is to have them talk to the person opposite each other about anything for 1~2 minutes.Once the time is up, the teacher says "switch" and those students of one row, take the next seat on the right to face a new talking partner(neighbour).You get the idea.
You could use any topic.Talk about your day/favourites/things you dislike/weekend plans/movies you've seen lately,etc.
If I notice a pair not speaking, they get a minute of extra time.
