Teacher GuideWeek 7 · Credit Cards, APR, and Consumer Borrowing
Essential question: How can a consumer compare credit offers by total cost rather than monthly payment or promotional language?
Instructional caution: Distinguish factual definitions, legal holdings, economic relationships, value judgments, and policy preferences. Do not grade students for political viewpoint; grade evidence, accuracy, reasoning, citation, and disciplinary method.
Mastery evidence
- Monthly payment alone does not reveal total borrowing cost.
- Paying only the minimum can extend debt for years and greatly increase interest.
- Promotional rates, balance transfers, rewards, fees, and penalty terms must be evaluated together.
Source / model emphasis
Compare three card disclosures using APR, fees, grace period, reward value, promotional end date, penalty terms, and total repayment.
Calculate repayment time and interest under minimum payment, fixed payment, and full-statement payment scenarios.
Daily Teaching Notes
Monday · Frame the Inquiry
Instructional aim: Define the Week 7 problem, establish the relevant institutions or economic relationships, and construct an initial answer to the essential question.
Evidence of learning: Identify one distinction that prevents a common oversimplification of this topic.
Support: Provide a vocabulary preview, chunked text, text-to-speech, and claim/evidence sentence frames.
Extension: Identify a competing theoretical interpretation and describe what evidence could distinguish it.
Tuesday · Source, Case, or Contract Laboratory
Instructional aim: Evaluate a primary record, legal case, policy document, contract, or institutional source for authority, evidence, context, and limitation.
Evidence of learning: State one claim the focal record supports and one claim it cannot establish alone.
Support: Define specialized language, provide a structured annotation guide, and allow oral rehearsal before writing.
Extension: Locate a source from a different institutional or social position and explain how it confirms, complicates, or contradicts the first.
Wednesday · Model, Measure, and Test
Instructional aim: Interpret a quantitative model, institutional process, financial calculation, or policy tradeoff without confusing description and causation.
Evidence of learning: Explain which conclusion remains valid after the changed assumption and which conclusion does not.
Support: Provide labeled examples, formulas or process steps, and a partially completed model.
Extension: Perform a sensitivity analysis or compare an alternative policy/institutional design.
Thursday · Argument, Deliberation, and Policy
Instructional aim: Construct and defend a precise claim using disciplinary evidence, a counterclaim, and a proportionate conclusion.
Evidence of learning: Explain why the counterclaim deserves a response rather than dismissal.
Support: Use claim-evidence-reasoning frames and permit an audio or oral draft before the final written product.
Extension: Rewrite the recommendation for an audience with a different role, jurisdiction, time horizon, or risk tolerance.
Friday · Assess, Correct, and Transfer
Instructional aim: Demonstrate weekly mastery, correct misconceptions, and transfer the central concept to a new case.
Evidence of learning: Apply the week’s reasoning to this mastery action: A student calculates total repayment under the actual APR and fees and does not select credit based only on the monthly minimum or rewards.
Support: Allow extended time, reduced-distraction setting, read-aloud where appropriate, and repeated attempts after documented correction.
Extension: Write one high-quality examination question and an answer key explaining why each distractor is wrong.

Constructed response
Should credit-card issuers be allowed to market rewards without showing a personalized likely interest cost?
5 points: clear claim, accurate disciplinary reasoning, two specific pieces of evidence, meaningful qualification or counterargument, and complete explanation.
