How to fill in a double bubble map
- Write the two topics in the big circles, for example two characters, two countries or two animals.
- List what they share. Each shared point gets a bubble connected to both topics.
- List what is true of only one. Put these on that topic’s outer side. Try to pair them up: if one side says “smooth skin”, the other says what its skin is like.
- Use it to write. The middle becomes your “similarities” paragraph and each side a “differences” paragraph.
Double bubble map or Venn diagram?
Both compare two things. A double bubble map gives every point its own bubble, which suits younger writers and long phrases. A 2 circle Venn diagram is more compact and is what maths and science questions expect. For essay planning, see the compare and contrast Venn diagram guide.
Questions people ask
What is a double bubble map?
A double bubble map is a thinking map for comparing two things. The two topics sit in large centre circles; similarities go in bubbles connected to both topics, and differences go in bubbles connected to only one. It is one of the eight Thinking Maps developed by David Hyerle.
What is the difference between a double bubble map and a Venn diagram?
They hold the same information: what is only true of A, only true of B, and true of both. A Venn diagram shows it with overlapping circles; a double bubble map uses separate bubbles and connecting lines, which leaves more room for writing and makes each point a separate item. Use the button under the map to turn your content into a 2 circle Venn diagram.
How many bubbles should a double bubble map have?
There is no fixed rule. Three to five similarities and three to five differences on each side is typical for a school task; this maker allows up to six per group so the map stays readable.
