What This Standard Means
What Students Need to Do
- Students explain why some Americans wanted overseas territories around 1898 and why others opposed taking them. They connect arguments about trade, naval power, self-government, and war to the debate over the Philippines.
What Mastery Looks Like
- Students can identify the position in a period source and support it with a specific detail. They can compare that position with an opposing view and explain what annexation meant for Filipinos seeking independence.
Common Misconceptions
- Students may assume all Americans supported expansion or that Filipinos had no independence movement. Some confuse the 1898 war against Spain with the later war against Filipinos.
How to Assess It
- Exit ticket: Why did some Americans support annexing the Philippines while others opposed it? Give one reason on each side and explain how Filipino independence shaped the debate.
