Rising Prices: What is Inflation?Activities & Teaching Strategies
Active learning transforms abstract economic concepts like inflation into tangible experiences that students can analyze and debate. By engaging in simulations and real-world data tracking, students move beyond memorizing definitions to observe how price changes affect households, businesses, and policy decisions in real time.
Learning Objectives
- 1Explain the concept of inflation as a sustained increase in the general price level.
- 2Identify and describe three primary causes of inflation: demand-pull, cost-push, and built-in inflation.
- 3Analyze how inflation affects the purchasing power of consumers and the real value of savings.
- 4Compare the impact of moderate versus high inflation on economic decision-making.
- 5Evaluate the significance of price stability as a macroeconomic goal for Singapore.

Simulation Game: Inflation Marketplace
Provide groups with play money and cards representing goods at initial prices. Introduce scenarios like increased demand or costs, then have groups bid and record new prices over three rounds. Conclude with calculations of purchasing power changes using a simple index.
Prepare & details
Why do prices for things sometimes go up?
Facilitation Tip: During the Inflation Marketplace simulation, circulate and ask probing questions like, 'Why did your group raise prices more than others?' to push students to connect their actions to broader economic principles.
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Data Hunt: CPI Tracker
Assign pairs to collect weekly prices for a basket of 10 common items from school canteen or online sources over four weeks. Plot price changes on graphs and compute a class CPI. Discuss if trends indicate inflation and possible causes.
Prepare & details
How does rising prices affect how much we can buy with our money?
Facilitation Tip: When using the CPI Tracker, assign specific sectors to pairs so students compare trends, then rotate discussions to highlight how some goods inflate faster than others.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Formal Debate: Causes of Inflation
Divide class into teams to argue for demand-pull versus cost-push as primary causes, using Singapore examples like oil prices or tourism booms. Each team presents evidence for 3 minutes, followed by whole-class vote and reflection.
Prepare & details
What are some simple reasons why inflation might happen?
Facilitation Tip: In the Debate: Causes of Inflation, provide a timekeeper and enforce structured rebuttals to keep discussions focused and ensure all perspectives are heard.
Setup: Two teams facing each other, audience seating for the rest
Materials: Debate proposition card, Research brief for each side, Judging rubric for audience, Timer
Personal Budget Challenge
Individuals create a monthly budget with $100, then apply 5% inflation to prices and adjust spending. Reflect in journals on trade-offs and link to real purchasing power loss.
Prepare & details
Why do prices for things sometimes go up?
Facilitation Tip: For the Personal Budget Challenge, require students to include a reflection paragraph linking their budget choices to the inflation scenarios they explored earlier.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Teaching This Topic
Teachers should introduce inflation with relatable examples, such as the rising cost of bubble tea or school supplies, to ground the concept before diving into causes. Avoid overwhelming students with too many causes at once; instead, scaffold learning by starting with demand-pull and cost-push before introducing built-in expectations. Research shows that students grasp inflation best when they see its effects through simulations and data analysis, so prioritize activities that let them experience the concept firsthand rather than passively receiving information.
What to Expect
Students will demonstrate understanding by explaining how different causes of inflation lead to uneven price changes and by applying this knowledge to analyze Singapore’s economic context. They will connect theoretical causes to practical outcomes, such as budget constraints or wage adjustments, using evidence from their activities.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring the Inflation Marketplace simulation, watch for students assuming all prices rise uniformly.
What to Teach Instead
Ask groups to present their pricing strategies and compare their results to a class chart showing relative price changes, ensuring students see that some sectors inflate faster than others.
Common MisconceptionDuring the Debate: Causes of Inflation, watch for students oversimplifying inflation as always harmful.
What to Teach Instead
Use the debate structure to have students defend both the benefits of moderate inflation and the drawbacks of high inflation, referencing real-world examples from their research.
Common MisconceptionDuring the CPI Tracker activity, watch for students equating a single price increase with inflation.
What to Teach Instead
Have students calculate the inflation rate for multiple goods over time and identify which sector’s rise is part of a broader trend versus an isolated event.
Assessment Ideas
After the Inflation Marketplace simulation, provide a short news clipping about a recent price increase (e.g., food, transport). Ask students to identify the type of inflation at play and explain their answer in 2-3 sentences, using evidence from their simulation experience.
During the Debate: Causes of Inflation, pose the question: 'Your salary increased by 3%, but inflation is 5%. How does this affect your purchasing power compared to last year?' Facilitate a class discussion on real versus nominal income, using the Personal Budget Challenge results to ground the conversation.
After the CPI Tracker activity, present a scenario: 'Global oil prices surge, raising transportation costs for businesses.' Ask students to write down the immediate impact on the general price level and classify the type of inflation, referencing the data trends they tracked.
Extensions & Scaffolding
- Challenge students to research a country with hyperinflation (e.g., Zimbabwe, Venezuela) and present how it disrupted daily life, using data from the CPI Tracker to contrast with Singapore’s stable rates.
- For students struggling with the Personal Budget Challenge, provide a partially completed spreadsheet with fixed expenses already entered to reduce cognitive load.
- Deeper exploration: Invite a local economist or business owner to discuss how inflation impacts their decisions, then have students prepare questions in advance based on their activities.
Key Vocabulary
| Inflation | A sustained increase in the general price level of goods and services in an economy over a period of time. This results in a decline in the purchasing power of money. |
| Purchasing Power | The amount of goods and services that can be purchased with a unit of currency. Inflation erodes purchasing power. |
| Demand-Pull Inflation | Inflation caused by an increase in aggregate demand, where 'too much money chases too few goods'. |
| Cost-Push Inflation | Inflation caused by increases in the costs of production, such as wages or raw materials, leading firms to raise prices. |
| Built-in Inflation | Inflation that arises from the process of adaptation and expectation, often involving a wage-price spiral where workers demand higher wages to keep up with rising prices, and firms raise prices to cover higher wage costs. |
