A Barter Game To Teach The Value Of Money As A Medium Of Exchange (and maybe spontaneous order?)

I created a barter game that I use in class. Each student gets a handout that lists 10 items that they own and ten items they need to get. Every trade has to be one item for one item. The students also get a sheet to record each trade they make. I set the time limit at around 20 minutes and they get extra credit for each item on their want list that they end up getting.

The table at the end of this post first shows the items they each own at the start of the game and then shows the items they need to get. What every player has and needs to get is different. There are only 12 unique players. So if more than 12 students show up, I start giving out player sheets that duplicate some that are already being used. Those students are probably in competition with each other and so may have a harder time than others. But I am not sure how to avoid this since I don't know ahead of time for sure how many students will show up. The game is set up for 12 players and, theoretically, they should all be able to trade for what is on their want list. If I set it up for more players, say 20, and not enough students showed up, then some students will have a hard time finding items on their list since the player sheet that has the items they need will not be in the game.

The link below will take you to a PDF file that has the 12 record sheets for each player. Each one has a table to record all the trades they made. Underneath that on each sheet is a table that shows the 10 items they start with ("Has") and then a list of the 10 items they want. My rules say that every trade is one item for one item (and Vitamins, for example, counts as just one item).

One issue is how hard to make the game. In the real world, if you had to rely on barter, you would probably have to make several trades before you got what you wanted (like trading good A to get good B, then trade B to get C, and finally trade good C to get good D). So I tried to set things up so that it would be hard to get some goods on your want list (requiring several trades) while others would need fewer trades to get.

For example, using the information from the table below, player #1 could make the following trades

Apple for Blender with player #11
Blender for Belt with player #9
Belt for Bed with player #7
Bed for Baseball with player #5
Baseball for Bag with player #3

Bag is on the want list for player #1. This takes 5 trades, quite alot of work (one issue in setting up these tables is that I have to make sure some of the other goods that each player has or wants can't be used-for example, in the case above, what if player #3 wanted a bottle-then he could trade his bag to player #1 for the bottle and only one trade needs to take place-this would make the game too easy).

In this example, player #1 has to make 5 trades. But the other players only make one trade, getting an item they want from player #1, so the game won't always be that hard. The story above involving player #1 finally getting his bag works for him getting his bottle and checkers. He would make 5 trades with those same five players involving other goods.

In this next case, player #1 only has to make three trades

Desk for Drums with player #4
Drums for Folder with player #7
Folder for Fries with player #10

Something similar would happen with the glove and lock.

In this next case, player #1 only has to make two trades

Organ for Phone with player #5
Phone for Plates with player #9

Something similar would happen with the radio and socks.

In the last case, only one trade has to be made. Player #1 trades his turkey to player #2 for his TV. Then players #3 & #4 can make just one trade to get a good. The same is true for the rest of the pairs of players.

So some trades are easy and others harder. Students have to walk around and find people to trade with. It does not take them long to realize that they have to form little groups and discuss what everyone has and wants. Then someone starts saying things like "if you trade me A for my B then you can trade B to get C from this other guy, which is on your list." This happens spontaneously, without me, the teacher, telling them to do this. What at first glance seems like it would be very disorganized or chaotic, ends up going fairly smoothly with quite a bit of cooperation. Often if someone says "I need good A" another student will say "that guy Joe over there has good A" or "you have good C? that woman over there needs it." Again, that is done voluntarily, without any direction from me. So an orderly process emerges without my directing it (I've see scalpers at sporting events try to find other scalpers who might have what you want if they don't).

I do tell them at the beginning that they will often have to make several trades to get what they want, but that is it. Then I just say "start trading" and give them a five minute warning before time is up. I might remind them during the game that if they trade for a good that they now own it and can trade it for something they want.

Once the game is over, I ask them questions such as "how would you like to do something like this every time you go to the store?" No one says yes because they just experienced how hard that would really be. It is much easier getting what you want with money.
