Why Do We Need Money?

Activity TypeGameDiscussion

Duration15–20 min

Description

This foundational activity is especially well suited to younger audiences. Participants first try a short barter exchange, then receive Monopoly money as payment for a small classroom task and use it to exchange for goods or services. They compare the two rounds before answering open questions about money, including its purpose, value, and control. The class identifies common questions and returns to them at the end of the Bitcoin Diploma to reflect on how their understanding has changed.

Objectives

Participants explain how money facilitates exchange across time and distance compared with direct barter, then reflect on questions for further learning.

Materials

Monopoly money
Simple “have” and “want” cards or classroom tokens representing goods and services
A small task card for each student
A board or paper to record results

Preparation Notes

Prepare a “have” and “want” card for each student. Make some wants deliberately difficult to match. Choose a quick, equal classroom task, such as sorting materials, solving a short puzzle, or tidying a shared area. Decide on a simple price for each good or service in the money round.

Setup

Explain that the class will try two ways of exchanging value. Remind participants that the cards and Monopoly money are classroom tools, not real money or a recommendation to use any particular currency.

Procedure

Step 1

Give each student a “have” card and a different “want” card. Allow a short barter round in which they can trade only when both people want what the other person has. Record how many participants obtain what they want and how long it takes.

Step 2

Give every student the same small classroom task. When it is completed, pay each student an equal amount of Monopoly money. Participants can now use the money to buy a good or service represented by a card, whether or not the person offering it wants what they have.

Step 3

Compare the rounds. Ask how money acted as an intermediary between people who did not have matching wants. Ask how a student could save the payment from today's task to use later, and how a shared money could help people exchange value with someone far away rather than only with nearby trading partners.

Step 4

Participants answer: Why do we need money? What is money? Who controls money? What gives money value? What question do you have about money?

Step 5

In groups, participants share answers, vote on five favorite answers, and share five favorite questions.

Step 6

Revisit the answers and questions at the end of the Bitcoin Diploma.

Key Points

Money can act as an intermediary, so people do not need an exact match of wants to exchange value.
A person can receive money for work now and choose goods or services later.
Shared money can support exchange across time and distance; direct barter is often limited to people who can find one another and have matching wants.

Discussion Questions

What made barter difficult? How did payment change the exchange? What could you do with payment that you could not do with a single good? How might exchange change if the person offering the good lived far away?

Notes

This is an intentionally basic introduction, most useful with younger audiences or participants new to the topic. Expand the exchange round with more goods, roles, time periods, or distant “markets,” or combine it with a barter activity or another activity on the functions of money when the group is ready for deeper exploration.
