Central Idea, Claims and Evidence: Grade 6 Study Guide
Sixth graders read nonfiction critically, checking whether claims are backed by solid evidence.
The central idea of a text is its main point, supported by key details. A good summary states the central idea and key points in your own words, leaving out your opinions. An argument in a text has a claim (the position), reasons and evidence (facts, statistics, examples, expert quotations).
Strong readers separate relevant and sufficient evidence from claims that are unsupported or off-topic, and notice how an author's word choices (connotation) and point of view shape the message.
Parts of an argument
| Part | Question to ask | Example |
|---|---|---|
| Claim | What does the author want me to believe? | Schools should have longer recess. |
| Reason | Why? | Exercise improves focus. |
| Evidence | What proof is given? | A study of 1,000 students showed better test scores. |
| Counterclaim | What is the other side? | Longer recess shortens class time. |
Evaluating evidence
Ask: Is it relevant to the claim? Is there enough of it? Is the source reliable, current and unbiased? Loaded words and emotional appeals (everyone knows, a terrible disaster) are not evidence. Compare how two authors present the same topic: what do they emphasize and what do they leave out?
One sentence.
Underline each.
Relevant? Enough? Reliable?
Strong, weak or mixed.
Summarizing
Write a summary in 3 to 5 sentences: the central idea first, then the key supporting points, using your own words. Do not add opinions or minor details. A useful frame is: The author argues that… She supports this with… She concludes that…
Worked example and common mistakes
Example: Claim: 'Recycling saves energy.' Evidence: 'Making a can from recycled aluminum uses about 5% of the energy of making it from raw material.' That is relevant, specific and checkable. Common mistakes: mixing up the topic with the central idea, accepting a claim because it sounds confident and including your opinion in a summary. Always ask 'How do they know?'
