What This Standard Means
What Students Need to Do
- Students gather clues from something made by someone who was there and from an account made later. They explain what each source helps them learn about an event.
What Mastery Looks Like
- Given a photo of students planting a garden and a later newsletter report, a student names one detail shown in the photo and one fact from the report. They explain why using both gives a fuller picture.
Common Misconceptions
- Students may think a photo tells the whole story, even when it cannot show why something happened. They may mistake a later summary for a firsthand account or assume one source must be completely right.
How to Assess It
- Show a photo of a school garden planting and a two-sentence newsletter recap that says why the garden was planted. Ask students to write one thing they learn from each and why they would use both.

Ways to Teach It
Give pairs an old classroom photo and a short history paragraph; have them place detail cards beside the source that supports each one.
Ask, "What can the old classroom photo show us that the paragraph cannot, and what can the paragraph explain that the photo cannot?"
Play Source Match: students pair event cards with a photo and a later report, then name one clue from each.
Show a school fair photo and a newsletter recap; ask which helps answer what people wore and why the fair happened.
