Step into the shoes of a History Detective and tackle some of history's toughest mysteries. These lesson plans guide students to evaluate conflicting evidence by:

  • Sourcing: Who made this source? Where did it come from?
  • Contextualizing: Imagine the setting surrounding this source: How was the world that made this source different than our own?
  • Corroborating: What do other sources say about the information in this document? Do they agree or disagree with what this document says?
  • Close Reading: What does the document say? Is it biased? What is the tone?

Equip your students with foundational tools that will help them evaluate conflicting information for the rest of their lives.
