4th grade Structure of informational texts 2/3

 In this session, we will explore the structure of informational texts and how visuals support

comprehension. We begin by defining what informational texts are and reviewing the different ways

that authors organize information.

Defining Informational Texts:

○ Informational texts provide factual information on topics such as science, history, or social studies.

○ They often include headings, subheadings, lists, and visuals to help organize information.

● Text Structures in Informational Texts:

○ Description: Describes a person, place, or thing in detail. Example: A passage describing the habitat of a particular animal.

○ Sequence/Chronology: Presents events in chronological order. Example: A timeline of a historical event.

○ Cause and Effect: Explains relationships where one event causes another.

Example: How deforestation affects local climates.

○ Problem and Solution: Presents a problem and offers one or more solutions.

Example: Discussing water pollution and methods to clean it up.

○ Compare and Contrast: Highlights similarities and differences between two or more topics. Example: Comparing different habitats or cultures.

● Visuals and Their Functions:

○ Visuals such as charts, graphs, maps, and diagrams help to organize data and illustrate relationships.

○ They support written text by making abstract concepts concrete and easier to understand.

○ For example, a diagram might show the water cycle, making it easier for students to see the steps involved.

● Using Context Clues and Reference Tools:

○ When students come across an unfamiliar word, they can use nearby words

(context clues) to infer its meaning.

○ They should also consult dictionaries or glossaries, especially when dealing with academic vocabulary from topics like wildlife or conservation.

● Signal Words:

○ These words indicate the text structure. Examples include "because," "therefore," "first," "next," "compared to," and "in contrast."

Practice Problems 

1. Problem 1: Which of the following best describes a text structure that explains why

something happens?

○ A. Compare/Contrast

○ B. Sequence

○ C. Cause and Effect

○ D. Description

Solution: C

Explanation: Cause and effect show why an event happens. Signal words like because or as a result are typical clues.

2. Problem 2: What is the purpose of a chart in an informational text?

○ A. To tell a fictional story

○ B. To give directions

○ C. To organize and show data

○ D. To list characters

Solution: C

Explanation: Charts are used to present data clearly, making it easier to understand

information.

3. Problem 3: Which signal word might indicate a compare/contrast text structure?

○ A. However

○ B. Therefore

○ C. Since

○ D. Next

Solution: A

Explanation: "However" is used to compare differences or show a contrast between ideas.

4. Problem 4: In a cause-and-effect text, what type of visual might help you understand the

relationship between events?

○ A. A timeline

○ B. A Venn diagram

○ C. A bar graph

○ D. A flowchart

Solution: D

Explanation: A flowchart shows the process and links events by cause and effect clearly.

5. Problem 5: What does a sequence text structure show?

○ A. How two things are the same

○ B. The order in which things happen

○ C. Why things happen

○ D. Descriptions of a person or place

Solution: B

Explanation: Sequence structure lists events in order, often using words like first, next, and finally.

6. Problem 6: When you see a diagram with arrows connecting ideas, what type of text structure are you likely looking at?

○ A. Problem and Solution

○ B. Cause and Effect

○ C. Sequence

○ D. Compare/Contrast

Solution: B

Explanation: Diagrams with arrows often show cause and effect, linking actions to

outcomes.

7. Problem 7: Which visual element would best help in understanding a process mentioned

in an informational text?

○ A. A photograph

○ B. A flowchart

○ C. A table

○ D. A map

Solution: B

Explanation: A flowchart depicts steps in a process, making it easier to follow a sequence.

8. Problem 8: Which of these best helps to find the meaning of an unknown word in a text?

○ A. Skipping the word

○ B. Using context clues and a dictionary

○ C. Ignoring the sentence

○ D. Guessing based on the title

Solution: B

Explanation: The best strategy is to use context clues and check a reference tool like a

dictionary.

9. Problem 9: What does the term informational text mean?

○ A. A fictional story

○ B. A text designed to entertain only

○ C. A text that provides factual information

○ D. A personal narrative

Solution: C

Explanation: Informational texts are written to give factual details, explain ideas, or

present data.

10. Problem 10: How can visuals help when reading an informational text?

○ A. They distract from the text

○ B. They only add color

○ C. They help organize information and show relationships

○ D. They replace the need to read

Solution: C

Explanation: Visuals support the text by organizing information and highlighting key

relationships or data.

● Key Takeaways:

○ Informational texts are organized by specific structures like cause/effect, sequence, and compare/contrast.

○ Visuals (charts, graphs, diagrams) help clarify facts and support understanding.

○ Using context clues, signal words, and reference materials increases vocabulary comprehension.

○ Understanding text structure helps with summarizing and retaining information from nonfiction texts.

● Exit Ticket Activity:

○ Write down on a small piece of paper or say verbally:

■ One text structure they learned about today and one example of a visual that helps understand information.

■ How they can use context clues to figure out the meaning of an unfamiliar word.

● Reflection Questions:

1. How do visuals in an informational text make it easier to understand the

information?

2. What strategies can you use when you come across a difficult word?

3. Which text structure do you think is the easiest to understand and why?
