Active learning ideas
This topic explores the mechanics of the marketplace, focusing on how the interaction between consumers (demand) and producers (supply) determines the price of goods and services. Students learn to read and interpret supply and demand schedules, eventually progressing to graphing these curves to identify the equilibrium price. This is a foundational skill in the NCCA specification, as it allows students to visualize how external factors like trends, weather, or income changes shift market behavior.
Activity 01
Run a live auction for a popular item, such as a homework pass or a snack. Track how many students are willing to pay at different price points to create a real-time demand schedule on the board.
What factors affect consumer demand?
Activity 02
Set up stations with different scenarios, such as a celebrity endorsing a brand or a sudden increase in the cost of raw materials. At each station, small groups must decide if the scenario affects supply or demand and draw the resulting shift on a mini-whiteboard.
How do producers decide how much of a good to supply?
Activity 03
Pair students who have mastered the equilibrium graph with those who are struggling. The 'guru' must explain the steps of plotting the X and Y axes and finding the intersection point, using a specific product example like concert tickets.
How is the market equilibrium price determined?
A few notes on teaching this unit
Watch Out for These Misconceptions
A change in price causes the whole curve to shift.
A change in price causes movement along the existing curve, while other factors (like tastes or income) shift the entire curve. Hands-on modeling with string or pipe cleaners on a large grid helps students physically see the difference between moving 'along' and shifting 'out'.
Supply and demand only apply to physical products.
These forces apply to services and even the labor market. Discussing the 'price' of wages in sectors like technology or hospitality helps students apply the model to the real world of work.
Methods used in this brief
Scarcity, Choice, and Opportunity Cost
Students explore the fundamental economic problem of infinite wants and finite resources. They learn how opportunity cost influences decision-making at personal and societal levels.

The Role of Government in the Economy
Students investigate how the Irish government raises revenue and allocates expenditure. They examine the impact of taxation and the national budget on citizens and businesses.
