Main Idea and Details Web
Centre idea with detail spokes.
The Main Idea and Details Web is a blank graphic organiser built around a central circle connected to surrounding detail bubbles by radiating lines. Students write their core topic or main idea in the centre, then populate each spoke with a supporting detail, example, or piece of evidence. It is widely used across Grades 1–6 for reading comprehension, non-fiction note-taking, and brainstorming before writing. Teachers appreciate the web format because it makes hierarchical thinking visible at a glance: children can see instantly how each detail connects back to one unifying idea. Because the template is entirely blank, it works for any subject — science facts, story summaries, social studies research, or creative writing prep. Parents homeschooling younger children find it especially useful for guided discussions about books or documentaries.

How to use this template
- Download the free printable PDF and print one copy per student (or display on a tablet for digital annotation).
- Write the main idea, central topic, or key concept in the large centre circle.
- In each surrounding bubble, add one supporting detail, fact, or example.
- Draw extra spokes and bubbles if more details are needed, or cross out unused ones.
- Use the completed web as a reference when writing a paragraph, summary, or report.
Classroom & home ideas
- Read a short non-fiction article aloud, then have students fill in the web independently to check comprehension.
- Use as a pre-writing organiser before students draft an informational paragraph about an animal, country, or scientific concept.
- Project a blank web on the whiteboard for a whole-class brainstorm at the start of a new unit.
- Ask students to swap completed webs with a partner and verify that every detail truly supports the main idea in the centre.
- Laminate a set of webs and place them in a literacy centre so students can reuse them with dry-erase markers throughout the year.

Frequently asked questions
How many detail bubbles does this web have?
The standard template includes six surrounding bubbles, giving students space for up to six supporting details. You can hand-draw extra bubbles if a topic needs more.
Can younger students in Grade 1 use this template?
Yes. For early writers, teachers often pre-fill the centre circle and guide students to draw or write a single word in each bubble. The visual structure helps even pre-readers grasp the concept of a main idea.
Is the template suitable for fiction as well as non-fiction?
Absolutely. Students can place a story theme or character name in the centre and add character traits, events, or feelings in the detail bubbles.
Can I use this digitally without printing?
Yes. The PDF can be opened in most annotation apps (Notability, GoodNotes, Adobe Reader) and filled in on a tablet or interactive whiteboard.
