Have the groups collaborate to create a story that links the original object with the last object drawn. Lead them to think about this by asking "What is the connection between the first object and the last object?" Have groups write a brief story using Etherpad or another collaborative document editing tool.
Finally, have learners present their stories to the group. Have participants talk about their stories.
Discuss the process of the activity and talk about the idea that procedural storytelling is a way of designing stories so that they're different every time. How did the activity illustrate this idea?
