50 Discussion Ideas for Double Circle Debating Lesson

The curricula strategy double circle, also known as inside-outside circle or onion, is used as a way of organizing discussion groups in the classroom. It is a type of peer work where students frequently change speaking partners. The inner and outer circles do not need to have the same speaking topic cards, but can each have a unique topic to talk about. It is a method of quickly discussing a range of issues and encouraging participants to think on their feet.

Key skill

The inner/outer circle debate strategy emphasizes listening to others’ views and writing an opinion essay.

The image below illustrates how this activity can be organised.


  • Listen to opposing or complementary views of others and respond to them appropiractely with their own ideas;
  • Contemplate and absorb multiple views on an issue, turn taking, and brainstorming out ideas;
  • Develop confidence when speaking, developing spontaneous responses in a group discussion;
  • Develop skills in supporting one’s opinion with facts and examples, leading a conversation.

What is the purpose of a double circle activity?

A double circle discussion is helpful for improving free speaking and fluency including the skills needed for active listening. Students can walk around the classroom, helping to increase attention and engagement. If the activity is timed, then it will be an important step to build confidence, develop thorough debate narratives, and quickly accumulate ideas for a range of issues.

Students can correct each other and help motivate those of varying skill levels to share their ideas.

What can do use a double-circle activity for?

  • It can serve as a way of comparing homework
  • It can be used for sharing opinions
  • Ideas concerning a specific topic
  • It can be introduced in different situations of a lesson:
  • At the beginning of a school year, it can be utilized as an activity of getting to know each other.
  • At other times it may be helpful for introducing topics, exchanging opinions, remembering content, or repetition of topics that had been introduced some time ago
  • To reduce anxiety and improve social contacts as well as get used to certain topics
  • Depending on the number of rounds of changing partners, carrying out the strategy takes about 30-45 minutes.

Lesson Plan

Arrange students into four groups of equal size. Arrange students in Group 1 into a circle of chairs facing out, away from the circle. Arrange students in Group 2 into a circle of chairs around Group 1, facing the students in Group 1. Groups 3 and 4 gather around the perimeter of the circle, facing the circle.

Select an issue that students will be motivated to discuss/debate. [see below]

Now, provide students in the inner circle with 10-15 minutes to discuss the topic. During that time, all other students focus their attention on the students in the inner circle. No one else is allowed to speak. Other students take notes about points those students bring up; notes are used in a follow-up classroom discussion and/or for writing an editorial opinion expressing a point of view on the issue at hand.


At the end of the inner/outer circle activity, students use their notes to formulate a cogent editorial opinion about the topic of discussion.
