Essential question: How do taxes affect take-home pay, purchasing decisions, and the public services a household relies upon?
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.
Compute a simplified federal tax using brackets, withholding, payroll taxes, and credits; then calculate effective and marginal rates.
Trace one federal, state, and local tax to the government receiving it and major services it supports.
Instructional aim: Define the Week 5 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.
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.
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.
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.
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 applies each tax bracket only to income within that bracket and distinguishes withholding, liability, and refund.
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.
Each principal assignment is worth 30 points: 8 accuracy, 8 evidence or calculation, 6 reasoning, 4 counterargument/limitation, and 4 clarity/citation. Use the course rubrics for expanded descriptors.

What makes a tax system fair: ability to pay, benefits received, equal rates, equal sacrifice, or another principle?
5 points: clear claim, accurate disciplinary reasoning, two specific pieces of evidence, meaningful qualification or counterargument, and complete explanation.
