Lesson Narrative
Students explore foundational economic principles including scarcity, opportunity cost, and resource allocation. They will utilize the PACED decision-making model and interpret Production-Possibilities Curves (PPC) to understand trade-offs, property rights, and environmental economics.
Learning Goals
• Define scarcity and calculate opportunity cost.
• Apply the PACED model to complex economic choices.
• Graph and interpret a Production-Possibilities Curve (PPC).
Student Facing Learning Goals
Let's learn how scarcity forces us to make difficult financial choices every single day.
Student Facing Learning Targets
• I can explain why scarcity exists.
• I can use the PACED model to make a decision.
• I can read a Production-Possibilities Curve.
Required Academic Standards
National Jump$tart Standards:
• Financial Responsibility and Decision Making (Standard 1): Take responsibility for personal financial decisions.
Glossary Entries
Scarcity: The basic economic problem that arises because people have unlimited wants but resources are limited.
Opportunity Cost: The value of the next best alternative given up when a choice is made.
PPC: Production-Possibilities Curve; a graph showing the maximum combinations of goods and services that can be produced from a fixed amount of resources.
Lesson
Warm Up
1.1.1: The Core Problem
Launch: Have students stand in randomized groups of 3 at vertical whiteboards. Present the prompt verbally. Give them 4 minutes.
Synthesis: Select two groups to share. Establish the baseline: Every choice has a cost. You cannot have everything, so economics is the study of how to allocate limited resources.
Student Facing Task
You have $50 and 2 hours of free time. You can either buy a new video game or go out to dinner with a friend.
1. If you choose the video game, what is your "opportunity cost"?
2. Why does the concept of "scarcity" make it impossible to choose both?
Activity 1
1.1.2: The PACED Framework
Launch: Keep students at whiteboards. Project the PACED model. Give groups 8 minutes to run the framework.
Synthesis: Have the class observe the boards. (Teacher Key: Ensure students clearly define Criteria before Evaluating Alternatives. Emotion must be removed from the decision).
Student Facing Task
You need to get to your new job every day.
Use the PACED model (Problem, Alternatives, Criteria, Evaluate, Decide) to choose between buying a cheap used car, taking the public bus, or riding a bicycle. Clearly list your criteria (e.g., cost, time, weather).
Activity 2
1.1.3: The PPC Graph
Launch: Project a blank PPC graph comparing two goods. Give groups 8 minutes to plot points.
Synthesis: Facilitate a class debate. (Key: Any point on the curve is efficient. Any point inside is inefficient. Any point outside is mathematically impossible with current resources).
Student Facing Task
A factory has limited workers and machinery. It can produce either 100 cars or 1,000 bicycles a month.
1. Draw a curve connecting those two maximums.
2. What happens to the production of cars if the factory decides it wants to build 500 bicycles?
3. Why can't the factory build 100 cars AND 1,000 bicycles simultaneously?
Lesson Synthesis
Narrative: Bring the class back to their seats. Review the learning targets. Summarize: "Economics is fundamentally the study of scarcity. We can't have everything we want, so we must build logical frameworks like PACED to make the most mathematically sound choices with the limited resources we have."
Cool Down
1.1.4: The Hidden Cost
Narrative: This exit ticket serves as a formative assessment on opportunity cost. Teacher Rubric: A successful response must identify that the cost of college is not just the tuition money; it heavily includes the lost wages they could have earned working full-time for those four years.
Student Facing Task
Explain why the true "opportunity cost" of going to college for four years is not just the tuition money you pay the school, but also involves the income you didn't make.
