Analyze the Declaration’s argumentative sequence without treating it as a complete account of lived equality.
▷ 2 teacher video choices: Read the Declaration as a Historical ArgumentGoal: Connect two specific textual features to the Declaration’s purpose and identify a question requiring other evidence.
Before this: Identify a claim, supporting reasons and a source’s date.
Try together: Together distinguish “The document asserts a principle” from “The principle was equally realized for everyone.” What evidence differs?

Try together: Discuss why “The Preamble names justice, so every action under the Constitution was just” does not follow.

Suggested grades 10–11 · Unit 2: Civil War and Reconstruction
Use a primary document and contextual note to challenge an overbroad summary.
▷ 2 teacher video choices: Read the Scope of the Emancipation ProclamationGoal: Evaluate a claim about the Proclamation by distinguishing its geographic scope, wartime context and later implementation.
Before this: Identify a document’s date, purpose and qualifying language.
Try together: Together explain why correcting the nationwide claim does not make the document historically insignificant.
United States History

Integrate the 14th Amendment’s language with a historical account of contested implementation.
▷ 2 teacher video choices: Connect Reconstruction’s Text and EnforcementGoal: Explain the relationship between a constitutional promise and an implementation struggle using two source contributions.
Before this: Distinguish a rule’s wording from evidence of its implementation.
Try together: Discuss what kind of evidence would be needed to evaluate enforcement in one community during a specified decade.
United States History
Suggested grades 10–11 · Unit 3: Migration and Civil Rights
Assess a one-cause explanation against an official historical overview and a clearly invented individual model.
▷ 2 teacher video choices: Evaluate Explanations of the Great MigrationGoal: Compare explanations for migration, identify their evidentiary limits and write a qualified multi-causal account.
Before this: Distinguish aggregate patterns from individual motives and evaluate competing explanations.
Try together: Together explain why finding one authentic wage-focused letter would not establish a universal motive.
United States History
Suggested grades 10–11 · Unit 3: Migration and Civil Rights
Use the 1964 Civil Rights Act as a source for legal change without assuming all later outcomes.
▷ 2 teacher video choices: Distinguish a Civil Rights Law from Its OutcomesGoal: Form a historical claim linking enactment and implementation and identify the evidence needed to assess it.
Before this: Analyze source purpose and distinguish enactment from enforcement.
Try together: Discuss why “A policy changed” and “Every experience changed immediately” are different historical claims.
