# Number Shuffle

Participants hold large single-digit signs from 0 to 9 and physically line up to display announced multi-digit numbers as quickly and accurately as possible. The group coordinates movement and communication across repeated rounds.

**Time:** 10 minutes. Source recommends playing for up to 5 minutes. UWT expands this to 10 minutes to allow for briefing, multiple rounds, and debrief.
**People:** 10 to 24. Teams of 10 participants, each holding one unique digit from 0 to 9; extra participants act as callers, spotters, or timekeepers.

## Choose this exercise

**Purpose:** Coordinate group movement and communication under time pressure to form designated multi-digit numbers.
**Use it when:** Use as an active energizer during team sessions, workshops, or transitions when a group needs physical movement and fast coordination.
**Skip it when:** Skip when the physical space is too cramped for safe movement, or when group members prefer quiet or stationary activities.

## Materials and tools

- 1 set of 10 large sheets of paper printed with digits 0 through 9 per 10-person team
- 1 flip chart or whiteboard with dry-erase marker
- Pre-written list of multi-digit numbers with no repeating digits (such as 407, 9,641, or 83,250)
- Digital timer or stopwatch

## Before participants arrive

1. Print or write digits 0 to 9 clearly on separate sheets of paper.
2. Draft a sequence of 6 to 10 prompt numbers where each digit appears at most once.
3. Clear an open floor space where 10 people can easily move past each other and form a line facing the audience or facilitator.

## Say this to open

Each of you holds one single-digit card from 0 through 9. When I call out and write a number, the people holding those exact digits must run up and form a line so the audience can read the number correctly from left to right. Everyone else steps back. Let us see how quickly and accurately you can assemble.

## How to run it

### 1. Distribute cards and explain rules (2 minutes)

Divide participants into teams of 10, or form one active 10-person line while remaining group members serve as callers, timekeepers, and judges. Hand one digit card from 0 to 9 to each active team member. Explain that numbers will be read from the perspective of the room facing the team.

### 2. Run initial practice rounds (3 minutes)

Call out a 3-digit number and write it on the board (example: 407). The participants holding 4, 0, and 7 step forward and line up in correct sequence from left to right as seen by the facilitator. Unused digits take two steps back. Confirm accuracy, reset, and call a 4-digit number (example: 9,641).

### 3. Execute timed challenge rounds (3 minutes)

Run 3 to 4 faster rounds with larger numbers up to 6 or 7 digits (example: 83,250 or 1,947,260). Track completion time on a stopwatch. Challenge the group to reduce their setup time while keeping the sequence completely accurate.

### 4. Debrief coordination strategies (2 minutes)

Bring the team together for a brief reflection. Hear observations from 2 or 3 participants about what communication tactics helped or hindered their alignment.


## Debrief questions

- What specific tactic helped the team organize into the correct order fastest?
- How did participants decide who took charge of positioning the line?
- What changed in your communication between the first practice round and the final timed round?

**Finished output:** A series of accurately assembled physical number lines completed within recorded challenge times.

## Remote

This activity requires physical movement and directional alignment that does not translate directly to standard videoconferencing. For an online group, run a digital card sort where 10 participants rename their video screen display names to single digits (0 to 9) and arrange themselves in a virtual gallery or drag numbered tiles onto a shared digital board in order. Label this online adaptation as Digital Number Sort.

## Hybrid

In a hybrid setting, in-person participants form the physical line holding the cards while remote participants serve as spotters and timekeepers, verifying accuracy via webcam and calling out navigation cues.

## Access and participation choices

- Participants with mobility limitations can participate from a seated row by holding up their card when their digit is called rather than running across the floor.
- Anyone preferring not to hold a card or move quickly may opt to serve as caller, timekeeper, or verification judge without disclosure.

## If the session gets stuck

**Participants arrange digits from their own point of view rather than the viewer perspective, reversing the number.**

Remind the group before each round that the line must be legible from left to right for someone looking at them from the audience.

**Multiple participants talk at once, creating confusion and slowing down the lineup.**

Pause between rounds and give the group 30 seconds to designate one caller or a standard alignment anchor, such as establishing the left-hand digit first.


## Terms used here

- No-repeat number: A multi-digit number in which each individual numeral from 0 to 9 appears only once.

## Participant material: Sample Number Prompt Sheet

Round 1 (3 digits): 407
Round 2 (4 digits): 9,641
Round 3 (5 digits): 83,250
Round 4 (6 digits): 179,342
Round 5 (7 digits): 5,820,631
Round 6 (7 digits): 4,901,873

## Sources and adaptation

Observed in Playmeo collection, where the activity is attributed to Mark Collard.

Retained core mechanic of assigning digits 0 to 9 and having participants physically assemble announced numbers from Playmeo. Added explicit roles for extra participants, timing brackets, hybrid considerations, access modifications, and structured debrief questions.
