What This Standard Means

What Students Need to Do

Students sort reasons for U.S. expansion into economic, religious, social, and political motives. They compare Social Darwinist claims with anti-imperialist arguments and responses from people the U.S. sought to rule.

What Mastery Looks Like

A student can explain how a call for new markets differs from a call for naval bases or Christian missions. They can identify Social Darwinism as a claim used to justify rule, then explain why an anti-imperialist and a Filipino independence supporter rejected it.

Common Misconceptions

Students may treat Social Darwinism as proven science rather than a racist argument used to justify conquest. They may assume all Americans supported expansion or that people in places the U.S. controlled responded alike.

How to Assess It

Exit ticket: List one economic, religious, social, and political reason given for U.S. expansion. Then explain how an anti-imperialist and a Filipino independence supporter might answer a Social Darwinist claim.

Lesson moves

Ways to Teach It

  1. Give pairs cards labeled markets, missions, racial hierarchy, and naval bases; have them sort short historical excerpts under each motive.

  2. Read an Anti-Imperialist League statement, then ask: How does its call for consent challenge Social Darwinist claims?

  3. Run a quote match using brief claims from Albert Beveridge, Mark Twain, and Emilio Aguinaldo; students name each speaker's position.

  4. Show Puerto Rico's presidential voting rules and ask how island residents' lack of a general-election vote relates to arguments about consent.
