Finding the main idea in non-fiction
Can do: Reads an informational page and states the main idea in one sentence, with two supporting details.
Why it matters
From Grade 3 onward most school reading is non-fiction, and it is read to extract something. Detail-collecting without a main idea is reading that produces nothing.
What it looks like when it's wobbly
Gives the most interesting fact instead of the main idea, or retells the whole page instead of summarising it.
⏱️ Two-minute check
Read one page of a non-fiction book. "What was that page mainly about — in one sentence?"
Solid looks like: A sentence covering the whole page, not the single most exciting fact in it.

One Sentence Summary
- 1Before reading, look at the heading and pictures and predict what it will be about.
- 2Read the page. Then close it — summarising with the page open turns into copying.
- 3"Tell me what it was about in one sentence. Ten words or fewer."
- 4Open it again and find two details that support that sentence.
- 5Compare their sentence to the heading. Headings are usually the main idea in disguise.
If it's too hard
One paragraph rather than a page.
If it's too easy
Summarise a whole chapter in three sentences, one per section.
Say this
"That's a detail, not the main idea. What was the *whole page* about?"
