Two-Four-Eight

Choose this exercise

Purpose: Introduce participants to several colleagues in escalating group sizes and reinforce recall through paired documentation.

Use it when: Use at the start of a multi-team meeting, training cohort, or workshop where attendees need to meet several peers quickly.

Skip it when: Skip when participants already know each other well or when the physical room is too constrained for three rounds of movement.

Group arrangement: Pairs merging into groups of four to six, then groups of six to ten

Timing: Relationship Makers Handbook suggests 15 to 30 minutes; 20 minutes fits an 8 to 24 person group.

Materials and tools

• One slide or chart displaying conversation prompts
• One pen per participant
• One sheet of blank paper or index card per participant
• One room timer or chime
• Shared digital document (for remote or hybrid sessions)

Before participants arrive

1. Display the conversation prompt list on a shared screen or wall chart.
2. Place blank paper and pens at each seat or table station.
3. Clear floor space so pairs and larger groups can stand and move freely.

Say this to open

Find a partner you do not know well. You have four minutes total, two minutes each, to interview your partner using a question from the screen. Then you will merge with another pair to introduce your partner. Share only what you are comfortable having repeated to others. Let us start in pairs.

How to run it

1. Interview in pairs 4 minutes

   Participants pair up with an unfamiliar peer. If total headcount is odd, form one triad. Each person asks their partner a question from the prompt list, such as a first job or memorable trip. Each speaker gets 2 minutes while the other listens and takes notes. Ring a chime at 2 minutes to switch speakers. In a triad, allocate 80 seconds per speaker, signaling at 1 minute 20 seconds and 2 minutes 40 seconds.

2. Merge into fours 5 minutes

   Each pair joins another pair to make four. If an odd pair or triad remains, combine them with an existing pair to make five or six. Allow 1 minute to move. Each person takes up to 45 seconds to introduce their partner. Call a halfway check at 2 minutes 30 seconds. In groups of five or six, remind members to keep introductions closer to 35 seconds so everyone finishes by 4 minutes.

3. Merge into eights 6 minutes

   Two clusters merge into an eight-person circle. If cluster sizes vary, combine smaller groups to keep circles between six and ten members. Allow 1 minute to merge. In turn around the circle, each person takes 30 to 35 seconds to introduce their original partner to the circle. Ring a chime at 3 minutes 30 seconds for the halfway mark, and call time at 5 minutes 40 seconds to finish.

4. Record and debrief 5 minutes

   Participants return to their original partner for 3 minutes. Each pair writes down the names of people met and details learned. Call the full room back together for the final 2 minutes. Ask two or three volunteers to share one detail learned about a peer, taking up to 30 seconds per volunteer.

Debrief questions

• Which detail that you heard today was the easiest to recall, and why?
• How did speaking on behalf of your partner feel compared to introducing yourself?
• What is one topic you learned about a peer that you would like to follow up on later?

Finished output: A written or spoken list of peers met during the session with at least one recorded fact for each person.

Remote

Use automated breakout rooms. Place participants into 2-person breakout rooms for 4 minutes. Regroup into 4-person breakout rooms for 5 minutes, then 8-person breakout rooms for 6 minutes. Reopen original 2-person breakout rooms for 3 minutes to record notes together in a shared digital document. Bring everyone back to the main room for the final 2 minutes for volunteer debrief sharing.

Hybrid

Pair in-person participants with on-site peers, and remote attendees with online peers in separate video tracks. Merge online rooms in exact parallel (pairs to quartets, then octets). Bring both cohorts together via shared room audio and main screen for the final 2-minute debrief.

Access and participation choices

• Participants may pass on any personal prompt and answer a neutral work-related question instead.
• Participants with mobility limitations may remain seated while other groups move to them.
• Writing notes is optional; participants may recall details mentally or listen without writing.

If the session gets stuck

An odd or irregular headcount prevents equal pairs, fours, or eights.

In Step 1, form one triad if total count is odd. In Step 2, merge remaining pairs into groups of five or six rather than leaving any isolated pair. In Step 3, merge groups so clusters stay between six and ten members. Adjust per-person speaking time slightly to fit.

A participant talks about themselves instead of introducing their partner.

Gently interrupt and remind the group before each rotation that the speaker's job is to introduce their partner to the new peers.

Terms used here

• Triad: A group of three participants formed when total numbers are uneven.
• Round-robin: Taking turns in sequence around a circle without interruption.
