Help your child find the main idea of a text
Teach your child to separate a text's topic, main idea and supporting details. Use an original passage, parent prompts and a quick check together.
For readers who can recall details from a short factual paragraph.
Help your child find the main idea by asking what the whole passage says about its topic. Read the complete paragraph before deciding. Then check whether the answer covers the important details, rather than only the fact your child remembers most clearly.
Understand the idea
The topic names what a text is about. The main idea states its central message about that topic. Supporting details explain or illustrate that message.
For example, "the library" names a topic. "The library gives people different ways to borrow and use books" states an idea about it. A sentence describing a returns slot might support that idea, but it does not cover everything a longer passage could say.
Say: "You have told me what it is about. Now tell me what the writer wants us to understand about it." This moves your child from a label towards a complete thought.
Headings and opening sentences can help, but the main idea is not always printed in one convenient place. The reader may need to combine details. Avoid teaching that the first sentence is automatically the answer.

A changed school newsletter
"The school newsletter used to arrive as a paper sheet. Now families can read it on a phone or collect a printed copy from the office. The online version includes links to permission forms. A noticeboard near the gate displays the week's key dates for people who do not open the newsletter."
Topic: How the school shares its news.
Main idea: The school uses several ways to make its news and information available to families.
Supporting detail: Families can collect a printed copy from the office.
A small detail
One interesting fact from the passage.
The main idea
The thought that connects the important details.
Your check
Does this summary explain most of the passage?
Read each sentence and ask how it fits the main idea. The phone version, printed copy, form links and noticeboard all describe ways to reach information.
"The newsletter is online" is too narrow because it leaves out the other options. "Phones are better than paper" adds a judgement the passage does not make. Explain those differences before asking your child to choose an answer independently.
Try it together
Choose an answer that covers the passage
Read this original passage:
"Before opening, the community hall volunteers check that the entrance is clear. They put out chairs and test the microphone. In the kitchen, another volunteer fills a water jug. The last person checks the booking list so each group knows which room to use."
Ask: "What is the main idea?"
Offer these answers after your child has tried their own:
- Volunteers prepare the community hall for the people who will use it.
- The microphone needs to be tested.
- Community halls should have bigger kitchens.
Ask which answer fits the whole passage and which details support it.
Check the answer
The first answer covers the entrance, chairs, microphone, water and room bookings. All are preparations for people arriving.
The second answer is true according to the text, but it covers only one task. The third is an opinion about kitchens that the passage never expresses.
A child might write, "Volunteers get the hall ready before it opens." That is also a suitable answer. They do not need to match the example word for word.
Check their understanding
Ask: "If I took out the microphone sentence, would your main idea still fit?" Yes, the other preparations still support it. This helps your child see the difference between one detail and the message joining several details.
Then have them invent a fitting detail, such as checking the lights. Ask why it belongs. Follow with an unrelated detail and let them explain why it would change or distract from the passage.
Make it easier or harder
For a reader who needs support, read aloud and underline related actions together. Ask what those actions are helping someone do. Begin with one paragraph on a familiar topic.
For a confident reader, use two paragraphs with different supporting details. Ask for the idea each paragraph develops, then the message they develop together. Distinguish a summary of events from a broader theme when moving to stories.
Teaching notes
The NSW Department of Education's Stage 2 main idea guidance distinguishes main ideas and supporting ideas. These passages and answer comparisons are original home activities, not official test items.
