Lesson Content/Board Summary

Comprehension: Main and Supporting Ideas in Informational Texts

What is an Informational Text?

An informational text is a piece of writing that gives facts and information about a particular topic. It teaches us about something real.

Main Idea

The main idea is the most important point or message the author wants to tell you about the topic. It is what the whole text is mostly about.

The main idea can often be found:

1. At the beginning of the text.
2. At the end of the text.
3. Sometimes, it is not directly stated but you can guess it from all the details.

Supporting Ideas/Facts

Supporting ideas or facts are details, examples, reasons, or explanations that help to prove, explain, or give more information about the main idea. They back up the main point.

Example: Healthy Eating

Text:

Eating healthy foods is very important for our bodies. Fruits and vegetables give us vitamins that keep us from getting sick. Foods like beans, eggs, and fish provide protein, which helps our muscles grow strong. Drinking plenty of water every day also keeps our bodies working well. When we eat healthy, we have lots of energy to play and learn in school.

Main Idea:

1. Eating healthy foods is very important for our bodies.

Supporting Facts:

1. Fruits and vegetables give us vitamins.
2. Beans, eggs, and fish provide protein for strong muscles.
3. Drinking plenty of water keeps our bodies working well.
4. Healthy food gives us energy to play and learn.

Instructional Procedures

Step 1: Introduction

Time: 5 minutes

Teaching Skill: Engaging/Activating prior knowledge

Teacher’s Activity: The teacher asks pupils what they remember from stories or news they have heard. The teacher then explains that every story or article has a main point and some details that explain it.

Pupils’ Activity: Pupils share what they remember from stories or news. They listen attentively to the teacher’s explanation.

Learning Point: Introduction to main ideas

Step 2: Explanation of Main Idea

Time: 7 minutes

Teaching Skill: Explaining/Defining

Teacher’s Activity: The teacher explains what a “main idea” is using simple language and examples. The teacher writes the definition on the board and points to the “Main Idea” section of the board summary.

Pupils’ Activity: Pupils listen, ask questions for clarity, and repeat the definition of “main idea” after the teacher.

Learning Point: Meaning of main idea

Step 3: Explanation of Supporting Ideas/Facts

Time: 7 minutes

Teaching Skill: Explaining/Illustrating

Teacher’s Activity: The teacher explains what “supporting ideas” or “supporting facts” are, emphasizing that they are details that prove or explain the main idea. The teacher writes the definition on the board and refers to the “Supporting Ideas/Facts” section of the board summary.

Pupils’ Activity: Pupils listen, contribute examples, and understand the role of supporting facts.

Learning Point: Meaning of supporting facts

Step 4: Guided Practice – Identifying Main Idea

Time: 8 minutes

Teaching Skill: Guided Reading/Facilitation

Teacher’s Activity: The teacher reads the example text “Healthy Eating” from the Board Summary aloud. The teacher then guides pupils to identify the main idea of the text, asking questions like, “What is this whole text mostly about?”

Pupils’ Activity: Pupils listen to the text, discuss possible main ideas, and collectively identify the main idea with the teacher’s help.

Learning Point: Identification of main idea

Step 5: Guided Practice – Identifying Supporting Facts

Time: 7 minutes

Teaching Skill: Questioning/Prompting

Teacher’s Activity: Using the same “Healthy Eating” text, the teacher guides pupils to identify the sentences or phrases that support the main idea. The teacher asks, “What details tell us why healthy eating is important?”

Pupils’ Activity: Pupils point out the supporting facts in the text and explain how they relate to the main idea.

Learning Point: Identification of supporting facts

Step 6: Application and Reinforcement

Time: 4 minutes

Teaching Skill: Group Work/Monitoring

Teacher’s Activity: The teacher divides pupils into small groups and gives each group a short informational text (e.g., a simple newspaper snippet on the environment). Each group is tasked with identifying the main idea and three supporting facts. The teacher monitors and assists.

Pupils’ Activity: Pupils work in groups to read their texts and identify the main idea and supporting facts. They present their findings to the class.

Learning Point: Application of skills

Step 7: Evaluation/Review

Time: 5 minutes

Teaching Skill: Questioning/Assessment

Teacher’s Activity: The teacher evaluates the learning by asking the following questions:

1. What is an informational text?
2. What is the main idea of a text?
3. What are supporting facts?
4. Read a short sentence and tell me its main idea and one supporting fact.

Pupils’ Activity: Pupils answer orally and in writing.

Learning Point: Assessment of understanding

Step 8: Note-Taking

Pupils’ Activity: Pupils listen and acknowledge the importance of the skill.

Learning Point: Consolidation of learning

Continuous Assessment/Further Study

Type: Homework

Instruction: Find a short article from a newspaper or a page from your science textbook. Read it carefully and then:

1. Write down the main idea of the article/text.
2. List three supporting facts that explain or prove the main idea.

Lesson Keywords

• Informational text – A text that gives facts and information.
• Main idea – The most important point or message in a text.
• Supporting facts – Details, examples, or reasons that explain or prove the main idea.
• Comprehension – Understanding what you read.

Differentiation

For weaker learners: Provide simpler, shorter texts with clearly stated main ideas. Guide them individually or in small groups to underline the main idea and then circle the supporting facts. Use flashcards with single sentences and ask them to identify the main point.

For faster learners: Provide more complex informational texts (e.g., slightly longer newspaper articles). Challenge them to identify the main idea when it is not explicitly stated and to summarise the supporting facts in their own words. Ask them to create their own short informational text and identify its main and supporting ideas.

Teacher Guide for Using This Lesson Plan

Before the lesson, select and prepare a few age-appropriate informational texts from newspapers, course books, or flash cards. Ensure these texts are on topics familiar or interesting to Primary 4 pupils, such as health, environment, or simple science facts. During the lesson, encourage active participation and discussion. When teaching the main idea and supporting facts, use the example text provided in the Board Summary first, then move to other examples. Guide pupils closely, especially during the initial identification stages, to build their confidence. For Step 8, ensure pupils copy the notes accurately. Check their understanding frequently by asking questions and observing their group work. Support struggling learners with simpler texts and more direct prompts, while challenging advanced learners with more analytical tasks. Remind pupils to apply this skill whenever they read.
