Inflation: Causes and MeasurementActivities & Teaching Strategies
Active learning helps students grasp inflation’s causes and measurement by moving beyond abstract definitions into concrete experiences. Students retain concepts better when they see supply disruptions, price pressures, and index calculations play out in real time rather than through lecture alone.
Learning Objectives
- 1Analyze the impact of demand-pull and cost-push factors on the Australian Consumer Price Index (CPI).
- 2Evaluate the consequences of unexpected inflation on the real returns for lenders and borrowers.
- 3Explain the trade-offs faced by individuals on fixed incomes, such as pensioners, due to inflation.
- 4Justify the Reserve Bank of Australia's inflation target range using economic reasoning.
- 5Calculate the real interest rate given nominal interest rates and inflation.

Simulation Game: Inflation Marketplace
Divide class into buyers and sellers with play money. Introduce cost shocks by raising supply costs, prompting price hikes. Groups track purchasing power changes over three rounds and report shifts in wealth between roles.
Prepare & details
Analyze how inflation redistributes wealth between lenders and borrowers.
Facilitation Tip: For the Inflation Marketplace simulation, circulate and listen for students who recognize price signals tied to shortages or wage hikes as causal factors.
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Pairs: Build Your CPI Basket
Pairs select 10 household items and assign base prices from ABS data. Simulate quarterly price changes based on scenarios like wage rises. Calculate index changes and discuss basket limitations.
Prepare & details
Explain the trade-offs created by inflation for fixed-income earners.
Facilitation Tip: When students Build Your CPI Basket, provide sample receipts to ground their choices in actual household spending data.
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Whole Class: Inflation Debate
Assign positions on 'Inflation is always bad' versus 'Low inflation is healthy.' Provide data prompts on RBA targets. Students prepare arguments in buzz groups before full debate with voting.
Prepare & details
Justify why a small amount of inflation is considered healthy for an economy.
Facilitation Tip: During the Inflation Debate, assign roles in advance to ensure balanced participation and prevent dominant voices from steering the discussion.
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Individual: Track Local Inflation
Students collect prices for five items over two weeks from shops or apps. Plot personal CPI line graph and compare to national data. Share findings in a class gallery walk.
Prepare & details
Analyze how inflation redistributes wealth between lenders and borrowers.
Facilitation Tip: For Track Local Inflation, remind students to use ABS CPI tables for consistent measurement and comparison over time.
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Teaching This Topic
Start with cause-and-effect activities before introducing CPI to prevent students from seeing inflation as only a statistical phenomenon. Use role-play and marketplace simulations to build intuition about price pressures, then introduce measurement concepts as a tool for tracking those pressures. Avoid jumping straight into formulas; build the need for the tool first through student experiences.
What to Expect
Students will explain demand-pull and cost-push inflation using real-world triggers, justify the CPI’s structure by adjusting a sample basket, and evaluate its limitations through debate and data analysis. Success is visible when they connect theory to evidence during simulations and discussions.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Inflation Debate, watch for students who claim inflation is always harmful to the economy.
What to Teach Instead
Redirect the debate by asking groups to find one benefit of moderate inflation (around 2 percent) and explain how it stabilizes debtors’ real obligations or signals healthy demand, using real examples from the simulation.
Common MisconceptionDuring Inflation Marketplace, watch for students who attribute all price rises to excessive money printing.
What to Teach Instead
Ask students to identify whether their assigned scenario (e.g., oil shock or rising wages) is a supply or demand issue, then link the outcome to price changes in the marketplace, emphasizing multiple causal pathways.
Common MisconceptionDuring Build Your CPI Basket, watch for students who assume the CPI accurately reflects changes in living standards.
What to Teach Instead
Have students adjust their basket to account for substitutions (e.g., switching to cheaper rice when beef prices rise) and explain how their revised weights reduce bias, revealing the index’s limitations.
Assessment Ideas
After Inflation Marketplace, present two new scenarios: one with excess demand and one with an oil price shock. Ask students to identify the type of inflation in each and write one sentence explaining their reasoning based on the simulation’s outcomes.
During the Inflation Debate, pose the question: ‘If you have $1000 saved and inflation is 5 percent this year, how much purchasing power do you lose?’ Facilitate a discussion on how this affects saving, spending, and debt decisions, connecting to the Reserve Bank’s inflation target.
After Track Local Inflation, ask students to define ‘real interest rate’ in one sentence and explain why the Reserve Bank of Australia aims for low, stable inflation, referencing the relationship between nominal rates, inflation, and purchasing power.
Extensions & Scaffolding
- Challenge: Ask students to research one country’s current inflation drivers and present a 60-second explainer using an infographic or data chart.
- Scaffolding: Provide a partially completed CPI basket template for students who struggle with weighting or substitution effects.
- Deeper exploration: Have students compare Australia’s CPI to another country’s inflation measure (e.g., US CPI or Eurozone HICP) and identify structural differences in the baskets.
Key Vocabulary
| Demand-pull inflation | Inflation caused by excessive aggregate demand in the economy, where 'too much money chases too few goods'. |
| Cost-push inflation | Inflation resulting from increases in the costs of production, such as rising wages or energy prices. |
| Consumer Price Index (CPI) | A measure of the average change over time in the prices paid by Australian households for a basket of goods and services. |
| Purchasing power | The amount of goods and services that can be bought with a unit of currency; it decreases as inflation rises. |
| Nominal interest rate | The stated interest rate before taking inflation into account. |
| Real interest rate | The interest rate adjusted for inflation, reflecting the true return to lenders and cost to borrowers. |
