Lesson 1: Lesson 1: Scarcity, Opportunity Cost, and Choice
Duration of Days: 3
Lesson Objective
Given a real-world scenario with limited resources, students will calculate the opportunity cost of an economic decision and diagram a Production Possibilities Curve (PPC) demonstrating trade-offs with 100% accuracy.
Students will analyze an informational text to evaluate how scarcity forces individuals and societies to prioritize competing needs and wants.
Why can't we ever have everything we want, and what do we actually give up when we make a choice?
How do individuals, businesses, and governments use the concept of opportunity cost to make rational financial decisions?
Scarcity,
Trade-offs,

Marginal Analysis.
7.Eco.4.a. Describe different types of economies (e.g., command, market, mixed). 2.Eco.1.a. Explain how scarcity and abundance influence decision-making in the community. MW.Inq.3.b. Organize and prioritize evidence directly and substantively from multiple sources in order to develop or strengthen claims.
Students practice analyzing line graphs (PPC) and tracking data shifts alongside complex technical prose, replicating SAT reading sections that combine text with data graphics.
Students will open the lesson by auditing their own finite resource—time. They will track a hypothetical budget, map out a personal production trade-off, and finish the lesson block by collaborating to build and shift a physical Production Possibilities Curve on a graph using string and markers.
The purpose of this lesson is to establish that nothing in economics is "free" and that every choice carries an invisible cost. DOK Level 2 (Skill/Concept) as students transition from defining choices to calculating mathematical trade-offs on a model.
Assessing the opportunity cost of choices high school students make today: choosing to work a part-time minimum wage shift on a Thursday night versus studying for an upcoming exam or playing in a varsity sports game.
Students frequently confuse "opportunity cost" with the monetary price of an item, forgetting that opportunity cost is specifically the value of the next best alternative foregone.
Provide learners requiring modifications with a partially filled-out matrix chart that explicitly separates "Alternative Chosen," "Monetary Cost," and "Next Best Alternative Foregone (Opportunity Cost)" to isolate the concept visually.
Present students with a scenario where a city must choose between building a new public park or a municipal tech hub. Students must write a paragraph identifying the opportunity cost of choosing the park and sketch a basic PPC illustrating the choice.
