Lesson 3: Lesson 3: The Law of Demand (Basic Application)
Duration of Days: 3
Lesson Objective
Students will be able to illustrate a downward-sloping demand curve based on a provided market schedule data table.
Students will be able to predict changes in consumer behavior when prices change by utilizing the Law of Demand.
ow do price changes directly influence our psychological willingness to buy goods?
How do businesses use consumer data to determine the optimal price for their products?
Law of Demand,
Demand Schedule,
Demand Curve,
Inverse Relationship,
Quantity Demanded.
Connecticut Social Studies Standards: 4.Eco.7.a (How profits and demand influence sellers), 6.Eco.3.a (Describe the role of supply and demand), and 7.Eco.6.a (Explain how changes in supply and demand influence price and quantity).
Connects directly to Words in Context and Data Synthesis. Students will practice identifying how terms like "inverse" or "marginal" function within an economics text, while pairing that textual definitions with a visual trendline.
Students will participate in a live classroom auction simulation for a popular item to see how their willingness to buy drops as the price climbs. They will take the aggregate classroom data, construct a demand schedule, and map it out as a downward-sloping demand curve. The lesson wraps up with a text analysis of how streaming services alter their subscription rates.
The goal is to introduce the foundational demand-side mechanics of market systems and show how human psychology interacts with market pricing. DOK Level: 2 (Skill/Concept).
Students will examine "hypebeast" culture, sneaker drops, or concert ticket price gouging (e.g., Ticketmaster dynamic pricing) to observe how price affects consumer demand in real time.
Students frequently confuse a change in "Quantity Demanded" (a movement along a fixed curve due entirely to a price change) with a wholesale shift in "Demand" (which shifts the entire curve due to outside factors).
Provide a graphic organizer that uses color-coded arrows (e.g., Price Up $\uparrow$, Quantity Demanded Down $\downarrow$) to firmly anchor the inverse concept before moving to the abstract graph.
Students complete a short-answer quiz where they are given a new demand schedule, must draw the corresponding graph, and must write an explanation of the visual trend using the phrase "inverse relationship."
