Which graphic organizer is described as having a spider map with a main idea and supporting details?

• A. Timelines
• B. Spider map
• C. Outline
• D. Venn

Answer: (B)

Graphic organizers help students visually structure ideas. A spider map centers the main idea in the middle and uses lines extending outward to show supporting details or related ideas. This layout resembles a spider’s web, which is why it’s called a spider map. It’s especially useful for brainstorming and planning when you want to see how details connect to the core idea. In contrast, a timeline places events along a line to show sequence, an outline uses a hierarchical list of topics and subtopics, and a Venn diagram uses overlapping shapes to compare and contrast. Because the description highlights a central main idea with branches for supporting details, the spider map is the best fit.
