Target: explain how purpose and audience affect the usefulness of a historical source for a claim. Prepare: Cards A/B, source compass.
- Launch · 2 min. Compare a public announcement and a private letter as kinds of writing, without judging one automatically truthful.
- Model · 4 min. Card A addresses a wider public and explains separation; Card B asks John Adams to consider women's voice in law. Point to one phrase from each.
- Guided reading · 5 min. Ask what B lets us infer about one writer's concern and what A tells us about Congress's public argument.
- Practice route · 7 min. Choose a Day 2 route. Build two purpose/audience/usefulness/limit records, one for each card.
- Audit · 4 min. Partner claims B speaks for all women; learner repairs to “Abigail Adams argued…” and says what broader evidence is missing.
- Exit · 3 min. “Which source best shows what Congress publicly argued?” Key: A; B is better for Adams's request, not a population survey.
