Course Guide Snapshot
Part 1 of Unit 3
Key Concepts to Know
These are the main topics students should be able to explain and apply.
Saving for Future Purchases
Individuals save for future needs and goals, considering opportunity cost, liquidity, and interest.
Borrowing, Credit, and Debt
Borrowers use credit to purchase now and repay later, but debt involves costs, risk, and responsibility.
Business Case Connections
Use these cases to connect vocabulary and concepts to business scenarios.
Personal finance: see the personal finance guides — plain-English explainers on credit scores, interest, and more.
Real-company case studies for Unit 3 (Tasks 1–2): Task 1: Acorns · Task 2: Affirm. Each has reading, practice, and discussion questions with sample answers (all case studies).
Personal Finance Context
Students apply saving and borrowing concepts to decisions they will make as consumers.
Household Decision-Making
Students evaluate trade-offs among saving, borrowing, and spending choices.
Project Connections
These project tasks connect the unit to the Business Canvas Project or Financial Advisor Project.
Financial Advisor Prep
Builds personal finance knowledge used later in the Financial Advisor Project.
See an example ↓
In the Financial Advisor Project you advise a family on money decisions. Unit 3A gives you the tools — for example, recommending they build an emergency fund, pay down a 22% credit card before investing, and start saving early so compound interest works in their favor.
Decision-Making Practice
Students compare costs and benefits of saving and borrowing options.
See an example ↓
Compare saving up $1,200 for a laptop over eight months versus financing it at 20% APR. Saving costs $0 in interest; financing could add well over $100 — a concrete cost–benefit comparison of saving versus borrowing.
See the worked Financial Advisor Project, and the personal finance guides for the concepts behind these decisions.
