Double Bubble Map Template and How It Works

A double bubble map template is a thinking map for comparing two things. Two large bubbles hold the topics, and a central area lists similarities shared by both. Each outer side lists the differences unique to that topic. The layout keeps comparison ideas organized before you write a compare and contrast essay.

  • Topic A bubble: traits unique to the first subject
  • Topic B bubble: traits unique to the second subject
  • Center overlap: similarities shared by both topics
  • Examples: concrete facts that support each point
  • Summary line: one sentence stating the main contrast

Use the finished map to plan an essay, revise before a test, or check your understanding. CogniGuide can build a personalized double bubble map from your own notes in minutes.
