Chapter 101: What Is Economics
👩 Teacher’s Guide
🎯 Objective
Students will be able to:
- Define economics as the study of how people make choices when resources are limited
- Distinguish wants from scarce resources
- Explain the role of incentives and trade-offs in everyday decisions
📝 Teaching Notes
- Key idea to emphasize: Economics is about choices, not just money
- Common misconception: Economics is only about stock markets or business profits
- Suggested teaching approach:
- Use a simple choice scenario (time, money, or snacks) to show scarcity
- Connect to real life: students deciding how to spend allowance or time after school
💬 Discussion Starter
Ask students:
- Think of a choice you made today. What did you give up to make it?
- Is a school cafeteria line an economic situation? Why or why not?
🧒 Student Worksheet
Concept and Helping Material
This topic explains:
- Scarcity: resources (time, money, materials) are limited, but wants are unlimited
- Choice and trade-offs: choosing one option usually means giving up another
- Incentives: rewards or penalties that encourage certain actions
- Opportunity cost: the best alternative you give up when you choose something
Why it matters:
- Understanding economics helps you make better decisions and explains why people, businesses, and governments act the way they do.
Vocabulary and Definitions
- — The study of how people make choices to use scarce resources to satisfy wants
- — The condition of not having enough resources to satisfy all wants
