Every simulation here runs the real model — the applets a teacher would put on the board, from GeoGebra, not a video of one. Pick a topic, open a card inside its lesson to run it next to the notes, or jump straight to the source. A simulation that fits several lessons is listed under each of them (58 cards in all).

A curved frontier for goods X and Y with a movable point E, a Productionfrontier slider and two tick boxes that switch the view.
A straight-line PPC for Item X and Item Y with three labelled points: Efficiency on the line, Recession (inefficiency) inside, Not Possible (yet) beyond.
Demand and supply lines with DemandShift and SupplyShift sliders and tick boxes for shortage, surplus, revenue and consumer and producer surplus.
Drag point E inside, onto and along the curve, then move the Productionfrontier slider to shift the whole frontier.
A straight-line PPC for Item X and Item Y with three labelled points: Efficiency on the line, Recession (inefficiency) inside, Not Possible (yet) beyond.
Move the DemandShift and SupplyShift sliders and watch equilibrium ME, price P1 and quantity Q1 move.
Drag point A along the demand line: read the elasticity εD and watch the shaded Expenditure rectangle grow, peak and shrink.
A tax diagram with labelled areas: buyer and seller surplus, the incidence on each side, the amount of tax per unit and the deadweight loss.
Demand and supply lines with DemandShift and SupplyShift sliders and tick boxes for shortage, surplus, revenue and consumer and producer surplus.
Supply and demand lines with a Price slider on the left. The controlled price line marks quantity supplied and demanded and shades the lost welfare.
Drag the green Price line up and down: the two shaded areas are consumer and producer surplus, and Total Surplus peaks at the market price.
Demand and supply lines with DemandShift and SupplyShift sliders and tick boxes for shortage, surplus, revenue and consumer and producer surplus.
A tax diagram with labelled areas: buyer and seller surplus, the incidence on each side, the amount of tax per unit and the deadweight loss.
Drag the dots on the demand and supply lines: watch the shares of the tax paid by buyers and sellers, and the deadweight loss, change.
Supply and demand lines with a Price slider on the left. The controlled price line marks quantity supplied and demanded and shades the lost welfare.
Drag the green points below the diagonal to bow the Lorenz curve; the table and the GINI Coefficient update as income gets less equal.
A step graph of marginal income tax rates (US, 2019). Drag the income point to read Income, Marginal Rate, Effective Rate and the tax paid.
Drag the blue handles to shift Aggregate Demand, SR Aggregate Supply or Long Run Aggregate Supply and watch PLe and Ye move.
Drag Aggregate Demand right to move Ye towards Y F (actual growth), then drag Long Run Aggregate Supply right (potential growth).
A curved frontier for goods X and Y with a movable point E, a Productionfrontier slider and two tick boxes that switch the view.
Aggregate Demand, SR Aggregate Supply and a vertical Long Run Aggregate Supply with blue handles to drag; PLe, Ye and Y F are marked on the axes.
Drag Aggregate Demand right for demand-pull inflation; put it back and drag SR Aggregate Supply left for cost-push. Compare PLe and Ye.
Aggregate Demand, SR Aggregate Supply and a vertical Long Run Aggregate Supply with blue handles to drag; PLe, Ye and Y F are marked on the axes.
Drag Aggregate Demand right to model higher government spending or lower taxes: Ye moves towards Y F and PLe rises.
A loanable funds diagram (real interest rates against quantity) with one slider, ΔG, for extra government borrowing; 'size of crowding out' is marked.
Drag Aggregate Demand right for a cut in interest rates and left for a rise; read the change in PLe and Ye.
A vertical Money Supply line and a downward-sloping Money Demand line, nominal interest rate against quantity of money, with handles to drag.
Drag Long Run Aggregate Supply right: full-employment output Y F rises. Then drag SR Aggregate Supply right and watch PLe fall.
A curved frontier for goods X and Y with a movable point E, a Productionfrontier slider and two tick boxes that switch the view.
Drag the blue handles on Demand or Supply of the currency and watch the exchange rate and quantity Qe change.
The market for Currency 1: Demand and Supply lines with blue handles to drag, the exchange rate (Currency 2 per Currency 1) and quantity Qe.
Demand and Supply lines with a movable Price line. Consumer and producer surplus are shaded with their values and Total Surplus is shown.
A curved frontier for goods X and Y with a movable point E, a Productionfrontier slider and two tick boxes that switch the view.
Slide q along the output axis and read Current ATC, AFC, MC and AVC; untick curves to study one at a time.
A price-taking firm: a horizontal price line P with MC and AC curves, Price and Quantity sliders and read-outs of AC, MC and total profit.
A total revenue line (Revenue = 8x) and a curved total cost line. Drag the point along the output axis to read Units, Revenue, Cost and Profit.
Drag the Quantity slider: read AC, MC, MR and profit. Profit peaks where MC equals MR, and the price is read off D=AR.
A price-taking firm: a horizontal price line P with MC and AC curves, Price and Quantity sliders and read-outs of AC, MC and total profit.
One firm in monopolistic competition: Demand, Marginal Revenue, Marginal Cost and Average Total Cost, with a slider h. It opens at long-run equilibrium.
Drag Quantity: profit peaks where the MC and MR read-outs match. Push on to where MR is 0 (most revenue) and see the profit given up.
A tax diagram with labelled areas: buyer and seller surplus, the incidence on each side, the amount of tax per unit and the deadweight loss.
Drag the green points below the diagonal to bow the Lorenz curve; the table and the GINI Coefficient update as income gets less equal.
A step graph of marginal income tax rates (US, 2019). Drag the income point to read Income, Marginal Rate, Effective Rate and the tax paid.
Aggregate Demand, SR Aggregate Supply and a vertical Long Run Aggregate Supply with blue handles to drag; PLe, Ye and Y F are marked on the axes.
A curved frontier for goods X and Y with a movable point E, a Productionfrontier slider and two tick boxes that switch the view.
