3.1 Text Features & Text Structures
Key Takeaways
- Print and graphic text features (headings, subheadings, captions, sidebars, diagrams, and glossaries) help readers locate key information efficiently.
- Grade 3 FAST ELA.3.R.2.1 assesses three informational text structures: chronology, comparison, and cause/effect—plus how text features contribute to meaning.
- Signal words like 'consequently,' 'in contrast,' 'first/next,' and 'as a result' provide explicit clues to identify an author's organizational framework.
- Analyzing how headings and diagrams work together deepens comprehension of complex non-fiction topics on the FAST ELA Grade 3 assessment.
3.1 Text Features & Text Structures
Florida B.E.S.T. Benchmark ELA.3.R.2.1 Focus: Explain how text features contribute to meaning and identify the text structures of chronology, comparison, and cause/effect in informational texts. (Central idea is a separate benchmark, ELA.3.R.2.2, covered in the next section.)
Assessed structures on Grade 3 FAST: The official ELA.3.R.2.1 benchmark names three structures—chronology, comparison, and cause/effect. Instruction may still mention other patterns (such as problem/solution or description) for reading strategy practice, but FAST items target the three named structures plus how text features contribute to meaning.
Informational texts are non-fiction writings designed to inform, instruct, or explain real-world topics to readers. Unlike stories or fictional narratives that follow a plot line with characters and settings, informational articles use specific design elements known as text features and organizational patterns called text structures. Master readers use these features and structures as roadmap tools to quickly locate information, understand complex scientific and historical ideas, and analyze how details fit together.
Part 1: Navigating Non-Fiction with Text Features
Text features are visual and organizational elements added to a text to help readers locate key information, clarify difficult concepts, and understand the organization of ideas. On the FAST ELA Grade 3 assessment, you will frequently be asked how a specific text feature supports your understanding of a passage.
Core Print and Graphic Features
| Text Feature | Visual Description | Primary Function / Purpose | How It Helps the Reader |
|---|---|---|---|
| Headings | Large, bold title text at the top of a major text section | Signals the main topic of an entire section or chapter | Helps readers predict section content and locate major topics |
| Subheadings | Smaller bold titles below a main heading | Breaks down a section into smaller, focused sub-topics | Allows readers to scan for specific details quickly |
| Bold & Italic Print | Heavy dark text or slanted letters | Highlights domain-specific vocabulary or key terminology | Signals that a word is important and often defined in context |
| Captions | Short explanatory text placed below or beside visuals | Explains what is shown in a photograph, chart, or drawing | Connects visual images directly to the surrounding text |
| Sidebars / Callouts | Text boxes offset on the side of the main body text | Provides extra interesting facts, historical context, or fun trivia | Gives supplementary information without interrupting main flow |
| Diagrams & Labels | Detailed drawings or illustrations with pointers | Visualizes the parts or internal workings of an object or organism | Shows how parts are arranged or function together visually |
| Glossary | Alphabetized word list located at the end of the text | Defines domain-specific vocabulary used in the text | Provides instant definitions without needing an outside dictionary |
| Index | Alphabetical list of topics and page numbers at the very back | Lists every page where specific names, places, or topics appear | Helps readers locate specific details across a full book |
Part 2: The Three Assessed Text Structures (ELA.3.R.2.1)
Text structure refers to the internal organizational pattern an author uses to arrange ideas, facts, and evidence in a passage. Recognizing text structures enables third-grade students to follow the author's logical progression of thought.
1. Chronological Order / Sequential Structure
- Definition: Arranges events, historical facts, or steps in the order that they happen in time.
- When Authors Use It: Biographies, historical articles, life cycles, and step-by-step experiment instructions.
- Key Signal Words: first, second, next, then, finally, before, after, initially, gradually, dates (e.g., in 1969, by 2024).
2. Cause and Effect Structure
- Definition: Explains why an event occurred (the cause) and what happened as a direct result (the effect).
- When Authors Use It: Scientific articles describing natural disasters, environmental changes, or historical impacts.
- Key Signal Words: because, since, as a result, consequently, therefore, due to, leads to, brought about, reason for.
3. Compare and Contrast Structure
- Definition: Examines two or more subjects, highlighting their similarities (compare) and differences (contrast).
- When Authors Use It: Comparing animal species, geographical regions, energy sources, or historical eras.
- Key Signal Words: similar to, likewise, both, in contrast, however, on the other hand, unlike, whereas, differs from.
Instructional patterns (not the Grade 3 assessed trio)
Authors sometimes use other organizational patterns in classroom reading. Know them for strategy practice, but remember that ELA.3.R.2.1 on Grade 3 FAST assesses chronology, comparison, and cause/effect.
- Problem and Solution: Presents a challenge and one or more ways to fix it (signal words: problem, issue, solution, resolve, remedy).
- Description: Lists characteristics or attributes of one topic (signal words: for example, such as, characteristics include, consists of).
Signal Word & Structure Quick Reference (Assessed Trio)
| Text Structure | Main Author Question | Signal Words to Spot | Example Sentence |
|---|---|---|---|
| Chronological | What is the sequence of events over time? | First, next, later, in 1995, finally | First, the sea turtle digs a nest in the sand; next, she lays her eggs and returns to the sea. |
| Cause & Effect | Why did this happen and what was the outcome? | Because, cause, effect, as a result, led to | Because water temperatures rose rapidly, the coral reef experienced severe bleaching. |
| Compare & Contrast | How are these two subjects alike and different? | Both, similar, however, unlike, on the other hand | Both alligators and crocodiles are reptiles; however, alligators have broad, U-shaped snouts. |
Part 3: Guided Passage Analysis
Read the sample Grade 3 informational passage below, then examine how text features and text structures work together to convey meaning.
Passage: The Journey of the Monarch Butterfly
Subheading: A Long Migration Each autumn, millions of monarch butterflies embark on an extraordinary journey. Because winter cold threatens their survival in northern North America, monarchs migrate up to 3,000 miles south to the warm pine forests of central Mexico. As a result of this dropping temperature, the butterflies fly in massive clusters to conserve energy.
Subheading: Threats and Solutions Recently, monarch populations faced a serious challenge: milkweed plants—the only food source for monarch caterpillars—were disappearing due to highway construction. To resolve this problem, school groups and gardeners across Florida began planting native milkweed gardens. Consequently, monarch caterpillars now have safe rest stops along their migration route.
Step-by-Step Analysis:
- Identifying Text Features:
- Subheadings: "A Long Migration" and "Threats and Solutions" break the passage into two clear focus areas: migration reasons and population challenges.
- Bold Print: The words "Because" and "milkweed" highlight cause-and-effect relationships and key botanical terms.
- Identifying Text Structures:
- Paragraph 1 Structure (Cause & Effect): The author uses signal words Because and As a result of to explain why monarchs travel south (cause: cold weather; effect: 3,000-mile migration).
- Paragraph 2 Structure (Problem & Solution): The author presents a problem (disappearing milkweed plants) and details a solution (planting community milkweed gardens).
Part 4: FAST ELA Test-Taking Strategies for Text Features & Structures
- Scan Features First: Before reading the main paragraphs, read the title, headings, subheadings, and captions to build a mental map of the text.
- Circle Signal Words: As you read, circle transitional words like because, however, first, and as a result. They reveal the text structure instantly.
- Match Feature to Purpose: If a question asks why an author included a diagram, look for what specific information the drawing shows that words alone could not easily explain.
A third-grade student is reading an article about sea turtles. Under the subheading 'Threats to Nesting Beaches,' the author describes how artificial beachfront lights confuse baby turtles and explains how coastal towns turned off lights to guide hatchlings safely to the ocean. Which text structure is used in this section?
Why do authors include captions beneath photographs in informational texts?
Read this sentence: 'Because ocean water temperatures rose higher than normal during the summer, coral reefs experienced severe bleaching; as a result, many marine animals lost their natural habitats.' Which signal words in the sentence indicate a cause-and-effect relationship?
