Reading Informational Text
The Reading Informational Text domain covers articles, biographies, science and history texts, and short arguments. Grade 5 questions ask you to state the central idea and explain which details support it, to recognize how a text is organized and how features such as headings and captions add meaning, to identify an author's purpose, and to trace how an argument is built.
Central idea versus topic
The topic is what the text is about (one or two words). The central idea is a sentence that says what the text teaches about the topic, and it may be stated or implied. Supporting details must point back to that sentence - an interesting fact that does not support the central idea is a distractor. A good summary states the central idea plus the most important details, in your own words.
Text structures and signal words
- Chronological or sequence: first, next, finally, in 1998
- Cause and effect: because, as a result, therefore, led to
- Comparison and contrast: both, unlike, however, on the other hand
- Problem and solution: the difficulty, to solve this, one answer
- Description or list: for example, also, another
Text features carry information
Headings announce sections, captions explain images, bold words are key terms, diagrams and timelines show relationships, sidebars add examples, and glossaries and indexes help you locate meanings. Questions often depend on a caption or a timeline date rather than the paragraph you remember.
Author's purpose and argument
Purpose is usually to inform, explain, persuade, or entertain. In an argument, find the claim, the reasons, and the evidence (data, examples, expert quotes). Notice the type of reasoning: logical (if this is true, then...) or empirical (measurements, observations). Loaded or emotional words signal the author's bias.
Worked example
Read: "Riverside Elementary's garden began as a bare dirt patch beside the gym. In its first year, students grew 40 pounds of tomatoes and peppers for the local food pantry. Science classes now test soil there weekly. The garden has become a working outdoor classroom."
Question: What is the central idea?
Reasoning: The first sentence sets up the change from "bare dirt patch," and the last sentence states the change directly: the garden became a working outdoor classroom. Each middle detail shows a different kind of value - food for the pantry and data for science. The central idea is that the garden became a valuable learning and community resource. "Students grow tomatoes" is a supporting detail, not the central idea.
Traps
- Choosing the most surprising detail as the central idea.
- Calling a comparison passage "cause and effect" because it uses the word "like."
- Ignoring a caption or timeline that contains the answer.
- Accepting a persuasive claim as proven fact.
- Summarizing by copying whole sentences instead of stating the main point.
