This is a great activity for time management and prioritization. It is typically used for focusing the conversation on fewer items with highest interest by the group.
Running the activity
1.      Instruct the participant on the voting rules:

 Each participant has 5 votes (each vote will be represented by a dot on the post it)
Participants can place more that one vote on a card.
Please vote on the items that you want to have a conversation about. The items with most votes will be picked up first.

2.      Go vote!
3.      Group conversation following the group interest order (most voted items first)
