Finding the main idea is the reading skill students are tested on most and taught least directly. These organizers make the relationship physical: one wide box at the top for the main idea, three or four narrower boxes beneath for the details that support it. If a detail does not fit under the stated main idea, either the detail is off-topic or — more often — the main idea has been written too narrowly, and seeing that on paper is far more convincing than being told it.

Blank organizers with a single main idea box across the top and three or four supporting detail boxes below it, connected by rules or lines. Some layouts use a table-and-legs shape, others a simple stacked format. All boxes are ruled for writing, with the main idea box sized for one or two sentences rather than a paragraph. Black and white, US Letter.

Frequently asked questions

How do I tell a main idea from a topic?
A topic is a couple of words — volcanoes. A main idea is a full statement about that topic — volcanoes form where the earth's plates meet. The main idea box on these sheets is ruled for a sentence rather than a phrase specifically to push students past the one-word answer.
What if a passage has more than one main idea?
Then it usually has more than one paragraph doing different work, and the honest answer is to use one organizer per section. Forcing a multi-part text into a single main idea box teaches students to over-generalize, which is the opposite of what the exercise is for.
Should the details be quoted from the text?
For a comprehension task, a short quotation or a close paraphrase is best because it keeps the link to evidence visible. For a planning task before writing, students' own phrasing is fine — the boxes are the same, the purpose is different.
Which grades get the most out of this organizer?
As an editorial suggestion, roughly ages 7 to 12. Younger students do well with three detail boxes and a shared text read aloud; older students can handle four boxes and an independent reading, and often benefit from being asked to write the main idea last.
