Now students take the facts from Phase 1 and relate them: mapping each response option against its consequences, interrogating real primary sources, and building an argument from evidence. Deep learning is where knowledge becomes usable — the bridge to the problem.
Build a class concept map with "Missiles found in Cuba — what should the U.S. do?" in the center. Around it, place the five real options ExComm weighed: do nothing · diplomacy · blockade/quarantine · airstrike · invasion. For each, cluster its possible consequences — and mark which ones risked escalation to nuclear war.
| Option | Possible upside | Risk / consequence |
|---|---|---|
| Do nothing | avoids provoking the Soviets | accepts missiles 90 mi away; looks weak |
| Diplomacy / back-channel | may resolve it without a shot | slow; missiles keep going operational |
| Blockade / "quarantine" | firm but leaves room to negotiate | a ship confrontation could spark war |
| Airstrike | destroys the missiles directly | kills Soviet troops; near-certain retaliation |
| Invasion | removes the threat and Castro | full war; possibly nuclear catastrophe |
Talk move: draw an arrow from any option to a consequence and say the cause-and-effect sentence aloud. This rehearses §113.41(c)(8)(B) and sets up the weighing of options in the Transfer phase.
Give pairs one or two real (district-approved) primary sources — for example a U-2 reconnaissance photograph of the missile sites, Kennedy's October 22 televised address, the two Khrushchev letters (the emotional first and the harder-line second), or the record of the secret Jupiter-missiles trade. Use a four-question source routine:
Corroboration & credibility check (c)(28): is this a first-hand record or a later account? Is it public or was it secret at the time? What other source would confirm or complicate it? How do we know?
📚 Primary sources & analysis tools: JFK Library · Kennedy's Oct 22, 1962 address ↗ · National Security Archive · documents & the Khrushchev letters ↗ · National Archives · DocsTeach: aerial photo of missiles in Cuba ↗ · LoC · Getting Started with Primary Sources ↗
A low-stakes rehearsal of the reasoning the problem needs. Pose a focused evaluative question and have students take a side with evidence, using a claim–evidence–reasoning frame. Then have them state the other side's strongest point (civil discourse) — this rehearses the evidence-based evaluation of §113.41(c)(28).
Sentence stems (ELPS support): "My claim is ______." · "My evidence is ______." · "This matters because ______." · "Someone who disagrees might say ______, but ______."
Note: keep this a practice argument about the general question. The specific October 1962 decision — with stakeholders in the room — belongs in Phase 3.
