What This Standard Means
What Students Need to Do
- Students separate an author’s proposed explanation, evidence, reasoning, and final claims. They check whether the numbers support the claims and compare the text with other reliable sources.
What Mastery Looks Like
- Students can explain how the evidence connects to the author’s claims and spot gaps in the reasoning. They can check calculations or trends and use a reliable source to support or challenge the conclusion.
Common Misconceptions
- Students may treat an expert’s title or a polished graph as proof. They may confuse correlation with causation, ignore sample size, or accept any source that agrees with the author.
How to Assess It
- Exit ticket: Provide a short report with a data table. Ask students to check one calculation, identify one unsupported claim, and name evidence needed from another source.

Ways to Teach It
Give pairs a printed research summary, calculators, and highlighters to mark claims, check one calculation, and flag unsupported conclusions.
Write one paragraph answering: Does the evidence justify the author’s conclusion, and what outside source strengthens or weakens it?
Use claim, evidence, and reasoning cards; teams race to build valid sets and explain why leftover cards do not fit.
Compare a news report about a medical study with the original study and a second reliable source, then list differences in their conclusions.
