Economics Activity
"Economics activity" is a broad search, and most teachers typing it aren't looking for another worksheet full of supply-and-demand vocabulary. They want something that gets students actually predicting how real people behave and then defending that prediction with something more solid than a guess. Incentive Detective does exactly that.
The setup is simple. Students pick one policy change: the minimum wage going up, a new local soda tax, or interest rates rising. Then they choose a stakeholder affected by it, a worker, a consumer, or a business, and build a case for how that person will respond. Not a hunch. A claim backed by evidence about the incentive at play and reasoning that connects the two.
That claim-evidence-reasoning structure is the same move a working economist makes every day. Forecasting behavior isn't about knowing the "right" answer in advance. It's about identifying the incentive a policy creates, predicting how a rational person responds to it, and being ready to explain why. Students who can do that have learned something that outlasts any single vocabulary quiz.
The activity closes with a twist: every policy creates a side effect nobody intended. A soda tax might just push shoppers to buy soda in the next town over. Asking students to spot that kind of ripple effect, and then compare notes with a partner who picked a different case, turns a solo prediction exercise into a real class discussion about how incentives actually play out.
This economics activity needs no login, no equipment, and no setup beyond picking sides for the debrief. It works as a standalone lesson or as part of a longer unit on how markets and policy interact.
It also scales well across a range of class sizes. A small group can run the whole activity as one shared discussion, comparing all three policy options side by side. A larger class benefits from splitting into smaller groups first, so more students get a chance to defend their reasoning out loud before the whole-class debrief. Either way, the structure stays the same: pick a case, build a claim-evidence-reasoning chain, then stress-test it against an unintended consequence.
What makes this different from a typical current-events discussion is the requirement to commit to a specific stakeholder and a specific claim before looking at anyone else's answer. That constraint is what turns a loose opinion into something closer to an actual economic argument, one a student has to be ready to defend when a classmate picks apart the reasoning.
Below is the activity exactly as it appears in the Rapunzl curriculum, followed by notes on running the debrief.
This economics activity is the Incentive Detective activity from Module 31: The Economic Way of Thinking in Rapunzl's grades 6–12 curriculum.
Incentive Detective
Predict how people will respond to a policy change, then defend your prediction using claim, evidence, and reasoning. This is a daily task for economists — forecasting behavior and building a rigorous case for why it holds.
Part 1 — Pick a case (individual)
Choose ONE: (a) the minimum wage rises, (b) a new local sales tax on soda, or (c) interest rates rise. You'll analyze how ONE group responds.
Part 2 — Claim–Evidence–Reasoning (individual)
Complete the CER framework for your selected case from the perspective of one of the following stakeholders: worker, consumer, or business.
- . Evidence (the incentive): . Reasoning (why the incentive drives it): .
Part 3 — Unintended twist (individual → group)
Identify one unintended consequence your policy could create over time (for example, a higher soda tax driving shoppers to a nearby town). Share it with your group, then note one case or prediction that differs from yours.
Teacher Notes
Let students choose their own case in Part 1 rather than assigning one. The variety matters for Part 3, since the debrief works best when different students picked different policies and different stakeholders.
Part 2 is the heart of the activity, and it's worth modeling once before students work independently. Put one example incentive on the board (a business facing a higher minimum wage has an incentive to raise prices, automate, or cut hours) so students see what a real claim-evidence-reasoning chain looks like before they build their own from scratch.
For Part 3, resist the urge to supply the "correct" unintended consequence. The point is that students generate one on their own, using the same forecasting logic from Part 2. When you regroup, ask students to compare their unintended consequence against a classmate's original case. Where do the two predictions agree, and where do they pull in different directions? That disagreement is usually where the best classroom discussion happens, since real policy debates rarely have a single obvious outcome.
Plan for roughly one class period: individual work for Parts 1 and 2, then a shift to small groups for Part 3.
