Now students take the facts from Phase 1 and relate them: weighing costs against benefits, questioning real sources from more than one point of view, and building a claim from evidence. Deep learning is where knowledge becomes usable — the bridge to the problem.
Build a class concept map with “Heading west in 1846” in the center. On the left, cluster the opportunities (why a family might go); in the middle, the dangers and costs; and on the right, the effects on Native peoples whose homelands the trails crossed. Then draw cause → effect arrows: what happened because so many families made this choice?
| Opportunities (the pull) | Dangers & costs | Effects on Native peoples |
|---|---|---|
| rich, cheap farmland | a months-long, risky journey | strangers crossing their homelands |
| a fresh start & more land | disease, weather, river crossings | pressure on land, water & buffalo |
| joining family & neighbors | leaving everything familiar behind | lost homelands as settlement grew |
Talk move: draw an arrow from any opportunity or cost to an effect and say the cause-and-effect sentence aloud. Point out how families adapted to and modified the environment along the way — this rehearses §113.16(c)(8)(A/B).
Give pairs two short (district-approved) primary sources that show different points of view — for example a brief pioneer trail-diary excerpt describing the hopes and hardships of the journey, and a source reflecting a Native nation's perspective on the wagons crossing their homeland. Use a four-question source routine:
Credibility check (c)(23)(B): is this a first-hand record or someone's later opinion? How do we know? Compare how the same journey looks from the wagon seat and from the homeland the wagons cross.

A low-stakes rehearsal of the reasoning the problem needs. 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).
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 choice. The specific family's decision belongs in Phase 3, where students hold stakeholder roles — including the perspective of a Native nation on the route.
