This collection of 10 interesting photos can be used to stimulate students in a variety of ways. For instance, in small groups they can be asked to produce a story based around any 5 of the pictures, in any order, which can then be presented to the class (with the pictures in a multimedia presentation).
This is useful to get students working together as a group, using a short time to apply some pressure. This can also be use as an extension to an improv session based on PechaFlickr.
