What you will be able to do
Starting point: No formal prerequisites.
Reason about transactions, credit, compounding, and discounting.
Use visual models to test assumptions and explain decisions.
One connected climb, not a topic dump.
The order is deliberate: later courses reuse the models, conservation laws, wave ideas, and mathematical language introduced earlier.
How the Economic Machine Works
Ray Dalio's simple template for the economy, transactions, credit, and three big forces, turned into things you can drag and test.
The Time Value of Money
Why a dollar today beats a dollar tomorrow, compounding, discounting, and NPV, as sliders you can push.
Supply & Demand
One market you can actually move. Drag demand, supply, taxes, and price controls, and watch price, surplus, and loss respond live.
The teaching toolkit
These reusable templates are available to lessons in this subject. Course content supplies validated data; templates supply the interaction.
Chart (2D)
Understand → AnalyzeBar, line, area, scatter, or pie — the everyday vocabulary for showing quantitative patterns.
3D chart
Analyze → EvaluateA rotatable view for a surface over two inputs or a genuine three-variable point cloud.
Quiz (MCQ)
Understand → ApplyMultiple-choice questions that check understanding and explain the answer — a checkpoint between ideas.
Decision tree
Analyze → EvaluateDecisions and chance events with payoffs — expected value rolled back, the best branch highlighted.
2×2 matrix
Analyze → EvaluatePosition items on two axes (BCG, risk/return, effort/impact) — draggable, with labeled quadrants.
Monte Carlo
Analyze → EvaluateSimulate an uncertain outcome across thousands of trials, then inspect its distribution and threshold probability.
Supply & demand
Understand → ExperimentAn interactive market: drag demand, supply, a tax, or a price control and watch equilibrium, surplus, and deadweight loss respond live.
