Key terms
- Objective summary.
- A restatement of the most important information in a text using only the facts and supporting details from the text, without the writer's opinions or personal reactions.
- Central idea.
- The main point or most important message that an author is communicating in a text.
- Supporting details.
- Specific facts, examples, or evidence in a text that explain or prove the central idea.
- Relevant.
- Connected to the main topic or central idea; directly related to the purpose.
- Extraneous.
- Not necessary or related to the main idea; extra information that can be left out.
- Synthesis.
- Combining information from different parts of a text to understand how ideas connect to the central message.
Worked example
Honey bees communicate through a special dance. When a bee finds a good source of pollen, it returns to the hive and performs a dance to tell the other bees where to find the flowers. The dance is quite beautiful to watch, with the bee moving in a figure-eight pattern. The angle of the dance shows the direction of the flowers relative to the sun. The distance the bee travels in the dance tells the other bees how far away the flowers are. Scientists have studied this dance for over a hundred years and find it remarkable. Thanks to this 'waggle dance,' hundreds of bees can find the same flower patch and bring back pollen efficiently.
Practice questions
Which of the following should NOT be included in an objective summary?
- The central idea of the text
- Key supporting details from the text
- Your personal opinions about the topic
- Evidence from the text that proves the main idea
Answer: Your personal opinions about the topic
You are summarizing a paragraph about the migration patterns of monarch butterflies. The paragraph mentions that monarchs travel thousands of miles, explains that they use the sun as a compass, gives an interesting fact that a single monarch can live up to eight months, and describes how their wings have special markings. Which of these details would most likely belong in a summary of the central idea 'Monarchs navigate migration using the sun'?
- The fact that they live up to eight months
- The distance they travel (thousands of miles)
- That their wings have special markings
- The interesting nature of their lifecycle
Answer: The distance they travel (thousands of miles)
Write an objective summary of this text: 'Coral reefs are underwater ecosystems that support thousands of species. They are built by tiny animals called coral polyps that produce hard skeletons. These skeletons stack up over time to form the reef structure. Coral reefs provide food and shelter for fish, sea turtles, and many other organisms. The colors and shapes of coral are stunning, and I think visiting a reef would be an unforgettable experience. Unfortunately, rising ocean temperatures are bleaching and destroying reefs around the world.' Your summary should be 2-3 sentences and include a conclusion starting with 'This shows that' or similar.
Answer: A strong answer would resemble: 'Coral reefs are ecosystems built by tiny animals called coral polyps whose hard skeletons form the reef structure over time. These reefs provide food and shelter for thousands of species, including fish and sea turtles. This shows that coral reefs are essential habitats that depend on a stable ocean environment.'
FAQ
- Is it okay to use exact sentences from the text in my summary?
- You may use a key word or short phrase if it is the clearest way to express an idea, but most of your summary should be in your own words. Copying long sentences verbatim is not summarizing—it is just copying. When you restate the text in your own words, you show that you understand the ideas, not just that you can find and paste information.
- How long should a summary be?
- A summary is typically much shorter than the original text—often about one-third the length or less, depending on how long and detailed the original is. For a one-page article, a good summary might be 3-5 sentences. For a longer text, it might be a paragraph or two. The length depends on how much support the central idea needs, not on a strict word count. Ask yourself: Have I included the central idea and the key supporting details in the clearest, most concise way possible?
- What if the text has more than one main idea?
- In Grade 6, you are focusing on texts with one clear central idea. If you encounter a text that seems to have multiple main ideas, look more carefully. Often those ideas are all supporting one larger, umbrella idea. For example, a text might discuss three different ways plants adapt to drought—but the central idea is probably 'Plants have different strategies for surviving drought.' Your summary would mention all three strategies as supporting details under that one central idea.
- Do I have to write my conclusion using the exact phrase 'This shows that'?
- No. 'This shows that' is one helpful way to introduce a conclusion, but you can also use similar phrases like 'As a result,' 'This illustrates that,' 'Therefore,' or 'Ultimately.' The key is that your concluding sentence restates the relationship between the supporting details and the central idea without adding new information or your own opinion. Choose whichever phrase sounds most natural in your summary.
