Double Bubble Map
Compare-and-contrast bubble layout.
A Double Bubble Map lays two subjects side by side, each with its own central circle, and arranges smaller bubbles around them. Bubbles that appear between the two centres show shared traits, while bubbles on the outer edges belong exclusively to one subject. This layout makes compare-and-contrast thinking immediate and visual — students can see at a glance what the two subjects share and what sets them apart. In grades 2 through 7, teachers use it across every subject: comparing two historical figures, two animals, two story characters, or two geometric solids. Because no topic names or labels are printed, the blank template is ready for any pair of subjects the lesson requires.
Learning objectives
- Identify similarities and differences between two subjects
- Organise compare-and-contrast details before writing
- Distinguish shared attributes from unique characteristics
- Build analytical thinking through side-by-side comparison
- Prepare for comparative essays or debate arguments
- Support critical reading by comparing two texts or viewpoints
How to use this template
- Print the blank double bubble map and write one subject in each of the two central circles.
- Fill the outer bubbles on each side with traits that belong only to that subject.
- Write shared traits in the bubbles positioned between the two central circles.
- Review the map and check that each bubble clearly belongs where it is placed.
- Use the completed map as a planning tool to write a compare-and-contrast paragraph or essay.
Classroom & home ideas
- After reading two versions of the same fairy tale, students compare characters, settings, or plot points on one double bubble map.
- In science, compare two biomes, two organisms, or two states of matter using the shared and unique bubble zones.
- Use it in social studies to compare two historical leaders, civilisations, or time periods.
- Pair it with a Venn diagram activity: have students complete both formats and discuss which one shows the differences more clearly.
- Before a class debate, each side completes one half of the double bubble map to prepare their argument points.

Frequently asked questions
How is a Double Bubble Map different from a Venn diagram?
Both show similarities and differences, but the double bubble map uses individual bubbles for each trait rather than overlapping circles. Many students find it easier to place discrete details in separate bubbles.
Can this template be used for more than two subjects?
The standard template is designed for two subjects. For three-way comparisons, students can use a Triple Venn diagram or connect a third bubble cluster by hand.
What grade level is the Double Bubble Map most appropriate for?
It works well from grade 2 upward. Younger students compare concrete objects or story characters; older students handle abstract comparisons such as two political systems or scientific theories.
How many bubbles are on this printable template?
The template includes two central circles plus several surrounding bubbles on each side and between the centres. Students can draw additional bubbles by hand if their comparison requires more detail.
