Students physically move into and out of a “wallet” (a specified area in the room) and note the change in the number of students in the wallet over time, as well as the inflow and outflow rates. This demonstration is then related to the stock (an amount at a point in time) concepts of assets and liabilities and the flow (an amount per unit of time) concepts of income and expenses. Students use this distinction to determine net worth, cash flow, and the relationship between them.
