Activity 01
Graphing Lab: Constructing AD Curves
Provide price level and spending data for C, I, G, X-M. Pairs calculate total AD at five price levels, plot points, and draw the curve. Discuss slope reasons in a 5-minute share-out.
Explain the components of aggregate demand.
Facilitation TipDuring Graphing Lab, circulate with sticky notes showing price levels and quantities so students can physically place points on the whiteboard to visualize the downward slope.
What to look forProvide students with a scenario: 'Due to a global pandemic, international travel is restricted, and domestic tourism increases significantly.' Ask students to identify which component(s) of AD are most affected and explain whether this would cause a shift left or right in the AD curve.

Activity 02
Shift Simulation: Policy Cards Game
Distribute cards naming AD shifters like tax cuts or rising interest rates. Small groups predict curve shifts, sketch before/after graphs on mini-whiteboards, and justify with component impacts.
Analyze the factors that cause shifts in the aggregate demand curve.
What to look forDisplay a blank AD curve on the board. Ask students to label the axes and plot a point representing a specific price level and quantity of real GDP demanded. Then, ask them to draw a second curve showing the effect of a decrease in business confidence, explaining their reasoning.

Activity 03
Component Role-Play: Economy Assembly Line
Assign roles as consumers, investors, government, exporters/importers. Whole class acts out spending changes at different price levels, then tallies total AD and graphs it together.
Construct an aggregate demand curve.
What to look forPose the question: 'If the Australian government decides to increase spending on infrastructure projects, how might this impact each of the components of aggregate demand, and what is the likely overall effect on the AD curve?' Facilitate a class discussion where students justify their answers.

Activity 04
Data Dive: Australian AD Analysis
Individuals access ABS data on recent C, I, G, X-M. They calculate percentage contributions, create pie charts, and note one shifter from news articles for class discussion.
Explain the components of aggregate demand.
What to look forProvide students with a scenario: 'Due to a global pandemic, international travel is restricted, and domestic tourism increases significantly.' Ask students to identify which component(s) of AD are most affected and explain whether this would cause a shift left or right in the AD curve.

Generate Complete Lesson→A few notes on teaching this unit
Teach this topic by building from micro foundations: connect household and business decisions to national spending, then scale up to the whole economy. Use analogies like a household budget to explain consumption, and a business expansion project for investment. Avoid teaching the AD curve as a static formula—emphasize it as a snapshot of planned spending at different price levels, constantly shifting due to external factors.
Successful learning looks like students accurately plotting AD curves, distinguishing movements from shifts, tracing how policy or events change components, and explaining effects on real GDP. They should use evidence from activities to justify their reasoning and correct common misconceptions through peer feedback.
Watch Out for These Misconceptions
During Graphing Lab, watch for students labeling changes in price level as shifts of the AD curve.
Pause the lab and ask pairs to plot two scenarios on the same axes: one showing movement along the curve due to a price change, and another showing a full curve shift due to a policy change like a tax cut, then compare the outcomes.
During Component Role-Play: Economy Assembly Line, students may count all household spending as consumption, including imports.
Assign students roles where importers and exporters must subtract import spending from total household outlays before calculating net exports, using receipts labeled with country of origin to make the correction visible.
During Shift Simulation: Policy Cards Game, watch for students believing that any change in spending shifts AD, including changes in actual output.
During the game, have teams track only planned spending components and explain why unplanned inventory changes do not count as shifts in AD when they record their policy outcomes.
