A circle map is a visual thinking tool used to brainstorm and define a single idea or concept. It consists of a small inner circle surrounded by a larger outer circle, with an optional rectangular frame drawn around the outside. Developed as one of eight Thinking Maps, it is one of the first graphic organizers taught in schools and is also used in professional settings for team brainstorming.
How a Circle Map Is Structured
A circle map has three parts, each with a specific job.
The inner circle holds the central topic. This can be a word, number, picture, or any symbol that represents the idea you want to explore. If a class is studying the concept of “weather,” for example, the word “weather” goes in the center.
The outer circle is the space between the small circle and the larger one drawn around it. Here you write everything you know, think, or associate with the central topic. For the weather example, you might write “rain,” “temperature,” “clouds,” “wind,” “seasons,” “forecast,” and so on. There is no wrong answer at this stage because the purpose is to get ideas on the page.
The frame of reference is a rectangle drawn around the entire map. This optional outer border is where you record how you know what you wrote in the outer circle. Did the information come from a textbook, a conversation, personal experience, or a documentary? The frame answers the question “How do you know this?” and helps justify the ideas inside the map. For younger students this part is often skipped, but for older students and professionals it adds credibility by connecting each idea to a source.
How to Create One
You can draw a circle map on paper, a whiteboard, or a digital canvas. The process is the same regardless of the medium.
- Write the central topic. Draw a small circle in the middle of your page and place the word, phrase, or image that represents your subject inside it.
- Draw the outer circle. Add a larger circle around the first one, leaving enough room to write in the space between them.
- Brainstorm freely. Fill the outer circle with anything related to the topic: facts, associations, questions, examples, or images. Don’t filter ideas yet.
- Add a frame of reference (optional). Draw a rectangle around the whole map. In the space between the rectangle and the outer circle, note where your information came from, whether that is a specific book, a class lecture, prior experience, or a teammate’s input.
- Review and refine. Look at everything in the outer circle. Group related ideas, cross out duplicates, and identify which items deserve deeper exploration.
Where Circle Maps Are Used
In the Classroom
Circle maps are typically the first Thinking Map students learn because the format is simple enough for young children. A kindergarten class might put the word “apples” in the center and fill the outer ring with colors, tastes, and places apples grow. The exercise helps students organize what they already know and reveals gaps in understanding, which makes it useful both before and after a lesson.
Teachers also use circle maps for vocabulary building. A student places a new word in the center, then surrounds it with synonyms, definitions, example sentences, and related images. For older students, filling in the frame of reference encourages them to cite where they learned each piece of information, building early research habits. The approach also benefits students who struggle with confidence: seeing their own ideas laid out visually can make abstract thinking feel more concrete.
In Professional Settings
Teams use circle maps during brainstorming sessions to collect every idea before evaluating any of them. Each person can contribute associations to the outer circle, which surfaces a wider range of perspectives than a simple round-table discussion. Once the map is full, the group reviews it together to identify the strongest or most feasible directions. The frame of reference is especially valuable here because it pushes team members to back up suggestions with data, customer feedback, or market research rather than gut feeling alone.
Circle Map vs. Bubble Map
These two tools look similar at first glance but serve different purposes. A circle map is for defining and brainstorming: you place a topic in the center and surround it with everything you know about it. A bubble map is for describing: you place a topic in a central bubble and then draw lines outward to smaller bubbles, each containing an adjective or descriptive phrase.
If the topic is “ocean,” a circle map might include facts like “saltwater,” “tides,” “marine life,” “covers 71% of Earth,” and “Pacific is the largest.” A bubble map for the same topic would focus on qualities: “vast,” “blue,” “cold,” “mysterious,” “salty.” The circle map captures knowledge and associations broadly. The bubble map zeroes in on sensory, emotional, or comparative language. Both can include a rectangular frame of reference to note the source or point of view behind the content.
Tips for Getting More Out of a Circle Map
Set a time limit when brainstorming. Five to ten minutes of unfiltered writing tends to produce more creative ideas than an open-ended session where people second-guess themselves. Write quickly, skip nothing, and save judgment for the review step.
Use images alongside words. Sketches, icons, or even color coding can help visual thinkers make connections they might miss in a text-only format. This is especially helpful for younger students or multilingual learners.
Revisit the map after learning more. A circle map created before a lesson or project kickoff becomes a powerful reflection tool when you return to it afterward. New items you can add to the outer circle show how much your understanding has grown, and outdated items you need to remove reveal earlier misconceptions.
