Instructional Guidance
Teaching notes
About 20 minutes. Recommended grades 6-8. Content area: social-studies.
Lesson Objectives
- Compare two primary accounts of the same historical event.
- Distinguish corroborated historical facts from a writer's role-specific focus and from the fictional story frame.
Likely language demands
- Students may treat a silence in the toll ledger as proof that mill workers were absent.
- Students may mention the fictional portal lens as if it were part of 1828 history.
What independent performance looks like
Independent performance contrasts the lockkeeper's toll record and the worker's letter with accurate chronology and zero confusion between fiction and history.
Follow-up
- Classroom studio: Family as Source (/studios/family-source), then History Portal adventure 2.
The History Portal and its guides (Imani, Rafael, and Ellis) are a fictional framing device. Early nineteenth-century stone canal locks, toll ledgers, and barge schedules reflect documented U.S. canal history, and students must cite only the historical documents, not the fictional portal.
