One Minute Problem

Choose this exercise

Purpose: Assess collective understanding of a specific topic by comparing written group responses across the room.

Use it when: During a training session or review when you need a rapid formative check on a concept that commonly triggers misunderstandings.

Skip it when: When the topic requires open-ended debate without clear criteria, or when teams need extensive background research to formulate an answer.

Group arrangement: Pairs or trios working simultaneously

Timing: Based on the 5 to 15 minute range in source materials; allocated as a 15 minute session to permit full review of up to 12 groups.

Materials and tools

• One large sticky note (5x8 inches) or half sheet of paper per group
• One bold marker per group
• Masking tape (if using plain paper)
• Whiteboard, flipchart wall, or designated wall space
• Prepared prompt slide or written display
• Countdown timer

Before participants arrive

1. Designate and clear a central response area on the wall or board.
2. Place one marker and one large note or paper sheet at each group table.
3. Prepare the target question, scenario, or problem display.

Say this to open

We are going to run a rapid check on this concept. In your group of two or three, you will have three minutes to discuss the prompt, settle on one agreed answer, and write it clearly on your large note. When time is called, one person will bring your note up to the wall.

How to run it

1. Present the prompt 1 minutes

   Display the single question or scenario on the screen or board. Read it aloud once without giving hints or early interpretations. Start the timer.

2. Discuss and write 3 minutes

   Small groups of two or three discuss the prompt. Members agree on one clear answer. One participant writes the agreed conclusion boldly on the provided note using two concise sentences or formulas. For example, if asked to identify a policy violation, the group writes: 'Violation of Section 3. The manager approved overtime without the director signature.'

3. Post answers 1 minutes

   One representative from each group walks up and posts their answer in the shared response zone on the wall. Cluster all notes in the same visual area.

4. Review and address misunderstandings 10 minutes

   Review the posted responses with the whole room. Read through 3 to 4 notes that show either common consensus or representative errors. Point out thinking errors and misconceptions directly. Invite 2 or 3 quick volunteer comments addressing the debrief questions to confirm the correct application.

Debrief questions

• Which posted solutions or answers show up across multiple groups?
• Where did our answers diverge, and what assumption caused that divergence?
• What is the key rule or correction to keep in mind based on these examples?

Finished output: A board of posted group responses showing current understanding across the room.

Remote

Display the prompt in the main video call. Send participants into breakout rooms of two or three for three minutes. Each group types their response on an assigned shared digital whiteboard note. Return to the main room, display the digital board, and sample cards to debrief misconceptions.

Hybrid

Group in-person participants with local peers using physical wall notes, and pair remote participants together in breakout rooms using a shared digital board. Project the digital board next to the physical wall in the room so all groups see both sets during the review step.

Access and participation choices

• Groups can select a writer or a poster, letting participants with mobility or handwriting constraints choose their preferred role.
• Any participant may contribute verbally or observe their small group discussion without an obligation to read aloud during whole-room review.

If the session gets stuck

Groups struggle to reach an agreed answer before the discussion time expires.

Give a 30-second warning and tell groups to record the majority conclusion, or record the core question they are debating if split evenly.

Handwriting on posted notes is too small to read from a distance.

Remind participants during step two to use the thick marker and limit their response to large lettering and short phrases.
