Phase 01: The Setup

Learning Objectives (Student-Friendly) By the end of this lesson, students will be able to: Explain what credit is and how it works Describe interest and minimum payments Calculate how much extra money interest can cost Identify smart vs. risky uses of credit Key Vocabulary (Non-Negotiable) Credit – Borrowing money you must pay back Interest – Extra money paid for borrowing Principal – The original amount borrowed Minimum payment – The smallest amount you’re allowed to pay Credit score – A number that shows how risky you are to lenders Hook (5 minutes) Scenario on the board: You want a new gaming console that costs $500.You have two choices: Save for 5 months and buy it. Put it on a credit card today. Ask students: Which option feels better right now? Which one costs more long-term? Do not answer yet. Let discomfort sit.

Phase 02

Phase 02: Deep Dive

Teacher Mini-Lesson

How Credit Works (10 minutes)
1. What Credit Is (Plain English)
Credit = using future money today.The lender charges interest because they want profit and because you might not pay them back.
No mystery. No morality. Just math + risk.
2. Interest (Where People Get Burned)
If you borrow $500 at 20% interest, you don’t just pay back $500.
You pay:
$500 (what you borrowed)
+ interest (the price of borrowing)
If you only make minimum payments, the interest keeps stacking.
3. Minimum Payments (The Trap)
Minimum payments:
Feel small
Take forever
Cost the most
Credit companies love minimum payments.They are designed to keep you paying interest as long as possible.

Discussion Questions:
Who gets richer in each scenario?
Why do people still use credit if it costs more?
When might credit actually make sense?
This is where thinking happens.

Phase 03

Phase 03: Reflection

Reality Check: When Credit Is Useful vs. Dangerous (10 minutes)

Credit Can Be Useful When

You can pay it off quickly

It helps you earn more money (education, reliable transportation)

You already have a plan

Credit Is Dangerous When

You don’t understand the interest

You only pay the minimum

You use it for wants instead of needs

You assume “future you” will fix it

Future you always pays the bill.
