This is a simple mingling activity that can be used with low level groups to provide practice in the past simple, particularly the question form. The lesson is designed for adults but could also be used with teenagers.
I use this activity as practice for using narrative tenses, particularly past simple and progressive/continuous with pre-intermediate students. It is a very structured activity in which students write a short newspaper article about a robbery.
I have found this game to be very popular with teenagers although it can be used with both younger learners and adult groups as well. I often use it as a warmer or as an end-of-lesson game. Although a pre-intermediate level of English may be required to understand the questions, even elementary groups might be motivated enough to try this game.
