Set the context
Prepare four pictures or photos representing different subjects (i.e.: a box with dog food, a fairy, a train, and a playground). Ask the learners to form groups of five to six and bring to their knowledge the following information:

“The city art gallery is in dilemma. A new exhibition with the title Hall of Thematic Photographers will be hosted. Four photographers sent their works for the exhibition, but according to the gallery manager, only three of them suit the theme of the exhibition. The work of one photographer needs to be declined: the one that is the least related to the works of the other three photographers.”

Assign task
Inform the learners that every group is actually a group of experts in the field of photography. In other words, every group represents the gallery manager: they need to formulate an argumentation to why the work of one photographer does not fit correctly with the works of the other three photographers, and hence, needs to be rejected. The task of the groups is to find creative ways to present the photographers and to convince the other groups why one is not related and needs to be rejected.

In alternative, if one or more groups feel confident enough, they can choose to present strong argumentations for showing the works of all four photographers, by finding or imagining links and similarities among all the pictures/photos.

In turn one group represents the gallery manager, and all the others are the audience.

Presentation of the argumentation
The presentations can take different forms, such as: a song, a dance, a story, etc. The groups get four minutes to prepare the presentations and four minutes to present each. At the end of each presentation, the other groups (the audience) provide comments and say whether they are convinced or not about the argumentation of the presenting group (the gallery manager). In the latter case, they have to provide explanations and eventually suggestions on how to improve it.
