Numbers: This can be done with as little as 5 people, though the numbers will dictate how much money is given out at the start.
Equipment: Monopoly money (or equivalent), 2 dice (sic?), life auction sheets, pencils.
Time: around 1 hour
Age: 11 and up.

The activity.
Give out 'life auction sheets' and ask people to rate what they thought was important in life fro the sheet, and to list their top 10 (1st most important, 2nd etc.)
Give out $1000 to each participant. Each person roles the 2 dice. They get an extra $50 for each number on the dice. But, if they get more than 7, they can roll one extra dice to add to their number, and if they get 12, they get to roll both dice again. This introduces a large degree of inequity into the game.
Announce that you are going to auction off all the items on the sheet. At this stage there is no mention of any connection between their listing and the auction. Auction off all the items starting at $100 each. Keep a note of who buys what.
When everything is gone (or all the money is gone), allocate points for what was purchased.
1st Preference 25 pts,  2nd - 20pts, 3rd - 16pts,  4th - 14pts,  5th - 12pts,   6th - 10pts,   7th - 8pts,  8th - 6pts,  9th - 4 pts,  10th - 2 pts, anything that hadn't been ranked - 1pt.
Get people to share how many items were purchased, and how many points they had.
Who had won? Did the person with the most items have the most points.
What items were important to people. Why?
