1. What is the first thing you should do when approaching an informational text?

Show Answer

Preview the text by reading the title, headings, introduction, and conclusion to get a sense of the topic and structure before reading in detail.

2. How do you identify the central idea of an informational text?

Show Answer

Look for the main point the author wants to convey, usually stated in the introduction and reinforced in the conclusion. Ask: "What is this text primarily about, and what does the author want me to understand?"

3. What is the difference between a fact and an opinion in informational writing?

Show Answer

A fact can be verified through evidence or observation; an opinion expresses a belief, judgment, or interpretation that may be debated. Look for signal words like "should," "best," or "believe" for opinions.

4. What should you annotate when reading informational texts?

Show Answer

Mark the central idea, key supporting evidence, vocabulary, transitions between ideas, author's purpose signals, and any questions or connections you have.

5. How do you evaluate the strength of evidence in an informational text?

Show Answer

Consider the source's credibility, whether the evidence is current and relevant, if there's sufficient quantity of evidence, and whether the evidence directly supports the claim being made.

6. What are text features in informational writing, and why are they important?

Show Answer

Text features include headings, subheadings, bold text, graphics, captions, and sidebars. They help organize information, highlight key points, and guide readers through complex content.

7. How do you identify an author's purpose in informational writing?

Show Answer

Look at word choice, included evidence, organizational structure, and what the author wants readers to think, feel, or do. Common purposes include to inform, persuade, explain, or analyze.

8. What strategies help you understand difficult vocabulary in context?

Show Answer

Use context clues from surrounding sentences, look for definitions or examples nearby, consider word parts (roots, prefixes, suffixes), and use the text's overall topic to make educated guesses.

9. How do you summarize an informational text effectively?

Show Answer

State the central idea, include only the most important supporting points, use your own words, maintain the author's intended emphasis, and keep it significantly shorter than the original.

10. What questions should you ask to analyze an author's perspective?

Show Answer

Ask: What is the author's background? What evidence does the author include or exclude? What assumptions does the author make? What biases might affect the presentation? Who is the intended audience?
