Using Captions and Images for Information
Using captions, bold print, subheadings, and glossaries to locate key facts efficiently.
About This Topic
Nonfiction text features are the tools that help readers navigate informational books and find facts quickly. In second grade, students move beyond just looking at pictures to using captions, bold print, subheadings, indexes, and glossaries. These features are essential for meeting Common Core standards that require students to use text features to locate key facts or information efficiently. Understanding these tools transforms a student from a passive reader into an active researcher who knows how to 'scan' for what they need.
Text features also provide vital context that the main body of text might skip. A map or a diagram can explain a complex concept in seconds that might take paragraphs to describe. This topic is highly engaging when students can participate in 'scavenger hunts' or collaborative investigations, using these features to solve puzzles or find specific answers. This hands-on exploration reinforces that nonfiction books are organized differently than stories and require a different set of reading strategies.
Key Questions
- How do images and captions add to the information provided in the text?
- Analyze how a photograph supports the main idea of a paragraph.
- Predict what information a caption might provide before reading it.
Learning Objectives
- Identify key facts presented in captions and bold print within informational texts.
- Analyze how a photograph supports the main idea of a paragraph by comparing visual elements to textual information.
- Predict the content of a caption by examining the accompanying image and subheading.
- Explain the function of a subheading in organizing information within a chapter.
- Locate specific information efficiently using a text's glossary.
Before You Start
Why: Students need to be able to identify the main idea of a text to understand how images and captions support it.
Why: Students must be able to identify and interpret images before they can analyze how they relate to text.
Key Vocabulary
| Caption | A short sentence or phrase that explains what is shown in a picture, photograph, or illustration. |
| Bold Print | Words that are printed using a darker, heavier type of lettering to make them stand out and signal importance. |
| Subheading | A title for a smaller section of a text that helps to organize information and tell the reader what the section is about. |
| Glossary | An alphabetical list of words found in a text, with their definitions, usually located at the end of the book. |
| Photograph | A picture taken with a camera, often used in informational texts to show real people, places, or things. |
Watch Out for These Misconceptions
Common MisconceptionStudents often skip over captions and sidebars, thinking they are 'extra' or unimportant.
What to Teach Instead
Use a 'Cover-Up' activity where you hide the captions and ask students to guess what is happening in the photo. When you reveal the caption, they see how much specific information they were missing, highlighting the feature's value.
Common MisconceptionStudents may think a glossary is the same as a dictionary.
What to Teach Instead
Explain that a glossary is a 'mini-dictionary' just for that specific book. Have students compare a glossary in a book about sharks to a standard dictionary to see how the glossary is more focused and helpful for that specific topic.
Active Learning Ideas
See all activitiesInquiry Circle: Text Feature Scavenger Hunt
Small groups are given a set of nonfiction books and a list of 'clues' (e.g., 'Find a word defined in a glossary'). They must race to find the features and explain to the class how that feature helped them understand the topic.
Stations Rotation: The Feature Fixers
At one station, students find a text with missing captions and write their own. At another, they create a subheading for a paragraph. This allows them to practice the 'why' behind each feature's existence.
Think-Pair-Share: Picture This
Students look at a complex diagram or map in a book without reading the text. They think about what they can learn just from the image, pair up to compare notes, and then share how the image added to the written words.
Real-World Connections
- Museum curators use captions to explain artifacts and photographs to visitors, helping them understand historical context and significance.
- Newspaper reporters and editors use bold print and subheadings to make articles easier to read and to highlight the most important information for readers scanning the news.
- Scientists writing research papers use glossaries to define technical terms so that other scientists and students can understand their findings.
Assessment Ideas
Provide students with a page from a science or social studies book. Ask them to circle all words in bold print and write one sentence explaining why they think those words are important. Then, have them read one caption and describe what the picture shows.
Give students a photograph and a short paragraph. Ask them to write a caption for the photograph. Then, ask them to write one sentence explaining how the photograph helps the reader understand the paragraph.
Present students with two versions of the same informational text: one without subheadings and one with them. Ask: 'Which version is easier to read? Why? How do subheadings help you find information more quickly?'
