What This Standard Means
What Students Need to Do
- Students gather details from artifacts, written sources, images, charts, graphs, and diagrams. They combine those details to explain a historical event and support a conclusion.
What Mastery Looks Like
- Students make a clear claim about an event using evidence from at least two source types. They explain how the evidence connects and note when sources differ.
Common Misconceptions
- Students may summarize each source separately instead of combining evidence. They may assume primary sources are always accurate or overlook labels, dates, scale, and source perspective.
How to Assess It
- Give students a photograph, diary excerpt, and simple graph about one event. Ask them to write one conclusion supported by evidence from two sources.

Ways to Teach It
Set up source stations with a replica artifact, map, letter, and graph, then have groups build an evidence board about one event.
Ask students to write: Which source best explains what happened, and which second source adds missing information?
Play Evidence Match, where teams pair claims with source cards and earn a point for explaining each match.
Compare a school event photo, announcement, and attendance chart, then explain how combining them creates a fuller account.
