How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: Which option best describes a summary that is too narrow?

Answer: It focuses on one example or small section instead of the whole text. Narrow summaries miss the big picture by focusing on minor parts.

Flashcard 2: Find the most objective wording: “The author foolishly ignores evidence” or “The author does not address counterevidence.”

Answer: “The author does not address counterevidence.”. The second option states facts without emotional judgment.

Flashcard 3: Identify the best summary characteristic: includes all details, or only key ideas?

Answer: Only key ideas and essential supporting points, stated briefly and accurately. Summaries condense texts to their most important elements.

Flashcard 4: What is the most objective way to refer to the author in a summary?

Answer: Use neutral phrasing such as “The text explains…” or “The author argues…”. These phrases maintain objectivity by attributing ideas to the source.

Flashcard 5: Identify what “elaborates” means in analyzing central idea development in a text.

Answer: Adds explanation, examples, or evidence to make an idea clearer and stronger. Elaboration deepens understanding through additional support and detail.

Flashcard 6: Which sentence is most likely a supporting detail rather than a supporting idea?

Answer: A specific fact, statistic, example, or quotation that proves a larger point. Details are specific pieces of evidence, not broader supporting points.

Flashcard 7: Identify the best central idea statement: “Recycling reduces waste and conserves resources.”

Answer: Central idea (a broad claim that can be developed across a full text). This makes a claim that could be supported throughout an entire text.

Flashcard 8: Identify the best way to show central idea development in notes: list details randomly or group by supporting ideas?

Answer: Group evidence under each supporting idea and connect each to the central idea. Organization shows relationships between ideas and their development.

Flashcard 9: What is the difference between a central idea and a topic in informational text?

Answer: Topic is the subject; central idea is the key claim about that subject. Topic names what it's about; central idea states what the author says about it.

Flashcard 10: What is a supporting idea in an informational text?

Answer: A major point that helps explain or prove the central idea. Supporting ideas are the main reasons or arguments that back up the central claim.

Flashcard 11: What is relevant evidence in informational text, in relation to a central idea?

Answer: Details that directly strengthen or clarify a supporting idea or central idea. Evidence must connect to and reinforce the ideas it's meant to support.

Flashcard 12: What is a central idea in an informational text (RI.8.2)?

Answer: The main point the author develops and supports throughout the text. It's the author's main message or argument that unifies the entire text.

Flashcard 13: Which question best helps you identify a text's central idea?

Answer: What message or claim does the author want the reader to understand overall. This question focuses on the author's purpose and main argument.

Flashcard 14: What does it mean to analyze how a central idea develops over the course of a text?

Answer: Track how the author introduces, expands, and refines it from start to finish. Look for how the idea is introduced, developed with evidence, and concluded.

Flashcard 15: Which text feature most often signals that a new supporting idea is being introduced?

Answer: A topic sentence or section heading that states a new main point. These text features clearly mark transitions between major points.

Flashcard 16: What is an objective summary of an informational text?

Answer: A neutral, accurate restatement of key ideas without opinions or extra details. Objective means factual and unbiased, focusing only on what the text says.

Flashcard 17: Identify the best central idea statement: “The author uses three examples of recycling.”

Answer: Not a central idea; it is a supporting detail about how the text is developed. This describes the author's method, not the text's main message.

Flashcard 18: Which option best describes how supporting ideas relate to a central idea?

Answer: They explain, clarify, or provide reasons and evidence for the central idea. Supporting ideas serve as the building blocks that prove the central claim.

Flashcard 19: What should you avoid including in an objective summary to keep it objective?

Answer: Personal opinions, judgments, and unsupported interpretations. These elements introduce bias and go beyond what the text actually states.

Flashcard 20: Which word best signals the author is drawing a conclusion: “therefore,” “for example,” or “meanwhile”?

Answer: Therefore. This transition word indicates a logical conclusion from evidence.

Flashcard 21: Identify the best revision to make this summary objective: “The author brilliantly proves air pollution is dangerous.”

Answer: “The author explains that air pollution is dangerous.”. Removing "brilliantly" eliminates subjective praise.

Flashcard 22: Which choice is a supporting idea (not a central idea): “Exercise benefits health” or “It lowers blood pressure”?

Answer: “It lowers blood pressure.”. Blood pressure is a specific benefit supporting the broader health claim.

Flashcard 23: Find the irrelevant detail for central idea “Plastic harms oceans”: “turtles ingest bags,” “microplastics in fish,” “plastic is colorful.”

Answer: “Plastic is colorful.”. Color doesn't relate to environmental harm; other details show damage.

Flashcard 24: Identify the best summary sentence for a text explaining causes and effects of drought.

Answer: The text explains major causes of drought and the impacts on people and ecosystems. This captures both aspects (causes and effects) neutrally.

Flashcard 25: Which detail best supports the central idea “Sleep improves learning”: “Students like naps” or “Memory tests improve after sleep”?

Answer: “Memory tests improve after sleep”. Test results provide measurable evidence; preferences are subjective.

Flashcard 26: What is the definition of a key detail in informational text?

Answer: A specific piece of evidence that directly supports a supporting idea or central idea. Key details are the specific facts that prove broader points.

Flashcard 27: Identify the best meaning of “relationship to supporting ideas” in CCSS.RI.8.2.

Answer: How supporting points connect to and strengthen the central idea. The standard asks students to analyze how support builds the main claim.

Flashcard 28: Which word best signals a supporting detail is an example: “however,” “for instance,” or “therefore”?

Answer: For instance. This phrase introduces specific examples to illustrate a point.

Flashcard 29: Which sentence is most objective for a summary: “The author foolishly argues…” or “The author argues…”?

Answer: “The author argues…”. Removing "foolishly" eliminates subjective judgment.

Flashcard 30: Identify the central idea in this set: topic = recycling; details = saves energy, reduces landfill use.

Answer: Recycling benefits the environment by conserving resources and reducing waste. This synthesizes the topic with the specific supporting details given.
