What This Standard Means
What Students Need to Do
- Students explain how disputes over slavery in western territories divided the North and South. They connect those disputes to states’ rights arguments, secession, and war.
What Mastery Looks Like
- Students can place major events in sequence and explain how each increased sectional conflict. They use evidence to show that many states’ rights claims focused on protecting slavery.
Common Misconceptions
- Students may name states’ rights or tariffs without explaining their connection to slavery. They may also confuse ending slavery everywhere with stopping its spread into new territories.
How to Assess It
- Ask: “How did the proposed expansion of slavery increase sectionalism and lead toward war? Use one historical event as evidence.”
