Introduction to Economics First Class Plan

Use this 50 minutes first-week plan to teach introduction to economics through one concrete decision. Students leave the first class able to describe economics as decision-making under scarcity, not as the study of money alone. The goal is to establish how economics class works: make a claim, use a model, test the claim, and revise it. It also gives the teacher useful diagnostic evidence without beginning with a long lecture.

The classroom prompt

A city must decide whether the next $1 million goes to bus frequency, park repairs, tutoring, flood control, or emergency response. Students choose, receive one new piece of evidence, and decide whether to revise.

Put the question where every student can see it and do not supply vocabulary before students commit to an answer. Their first explanation becomes the evidence you use during the debrief.

Materials and setup

Prepare a fictional city budget with five programs, benefit estimates, and a hard spending cap plus index cards for individual choices.

Open the learn economics guide if you want students to test the same idea on an interactive model after the paper task. A projected version is enough; students do not need accounts for this lesson.

Run the lesson

Answer key and teacher moves

• The problem is economic because desirable uses exceed available resources.
• The opportunity cost is the most valuable alternative not chosen.
• New marginal evidence can rationally change a choice without making the first decision irrational.
• Money measures the constraint here, but the underlying subject is allocation and tradeoffs.

Do not give credit for the correct direction alone. Ask students to name the changed determinant, identify the curve or quantity that changes, and connect the change to the final outcome. A complete explanation contains a cause, a model move, and a result.

What to collect

Collect the initial and revised choices plus a short explanation of what evidence did or did not change the decision.

Most likely misconception: Students define economics as stocks, banking, or how to make money rather than choices under scarcity.

Support and extension: Read program cards aloud and use icons. Extend by asking students to propose a decision rule and critique what it leaves out.

A clean closing question

End with: What changed, what stayed fixed, and what evidence proves your conclusion? That sentence works as the final written check because it forces students to separate a cause from the movement it produces. Collect it, scan for the misconception above, and use the first three minutes of the next class to repair the pattern if needed.

This resource is ready to copy into a slide, handout, or LMS assignment. If you assign it for points, publish the success criteria before students begin: correct model, correct direction, and an explanation that links the two.
