Categorize stories in 2 dimensions to identify boring ones Source:

Draw a big square and divide it into 2 columns. Label them 'Interesting' and 'Dull'. Let the team write down everything they did last iteration on stickies and put it into the appropriate column. Have them add a rough estimate of how long it took on each of their own stickies. Now add a horizontal line so that your square has 4 quadrants. Label the top row 'Short' (took hours) and the bottom row 'Long' (took days). Rearrange the stickies in each column. The long and dull stories are now nicely grouped to 'attack' in subsequent phases.
Split a large group into smaller ones that create posters Source:

After you've identified an important topic in the previous phase you can now go into detail. Have the larger group split up into groups of 2-4 people that will each prepare a poster (flip chart) to present to the other groups. If you have identified more than one main topic, let the team members select on which they want to work further. Give the teams guidelines about what the posters should cover / answer, such as:
What exactly happens? Why is that a problem?
Why / when / how does this situation happen?
Who benefits from the current situation? What is the benefit?
Possible solutions (with Pros and Cons)
Who could help change the situation?
... whatever is appropriate in your setting ...
The groups have 15-20 minutes to discuss and create their posters. Afterwards gather and each group gets 2 minutes to present their results.
Let team members appreciate each other and end positively Source:

Start by giving a sincere appreciation of one of the participants. It can be anything they contributed: help to the team or you, a solved problem, ...Then invite others and wait for someone to work up the nerve. Close, when no one has talked for a minute.
