What This Standard Means
What Students Need to Do
- Students identify how Native peoples, explorers, missionaries, miners, railroad workers, and leaders shaped the region that became Idaho. They explain how travel, settlement, and government changed before statehood, including effects on Native communities.
What Mastery Looks Like
- A student can explain how Sacagawea helped Lewis and Clark, why miners drew settlers, and how William Wallace helped govern the territory. They can name a cost of settlement for Native peoples and explain that Native communities remain in Idaho.
Common Misconceptions
- Students may think Lewis and Clark founded Idaho or that Idaho became a state soon after their visit. They may see Sacagawea as a passenger rather than an interpreter, or think Native peoples disappeared when settlers arrived.
How to Assess It
- Exit ticket: Explain how Sacagawea helped an expedition, why miners brought more settlers, and one effect settlement had on Native peoples.

Ways to Teach It
Make a string timeline marked 1805, 1860s, 1863, and 1890; pin Lewis and Clark, miners, and William Wallace near their dates.
Ask: How could a mining camp help a newcomer but harm a Native community? Have students write one effect for each.
Give pairs cards for Sacagawea, David Thompson, and William Wallace; match each to interpreter, mapmaker, or territorial governor, then name one effect.
On an Idaho road map, locate Lemhi Pass and nearby roads; ask why travelers used a pass instead of crossing mountain peaks.
