Help me prepare and run the exercise below. First ask for my participant count, time, setting, access needs and intended result. Check these against the stated limits. Use the supplied rules and materials. Explain any proposed changes before using them, and label them as adaptations. Do not invent source claims or require personal disclosure. Give me one step at a time when I say start. I manage the people, physical activity and clock; do not claim to observe the room. Ask me what happened before choosing a next step.

# Think Ball

Two teams compete as batters and fielders using numbered tennis balls. A batter scatters sixteen numbered balls and runs laps around their line while the fielding team sorts the balls into four designated hoops.

**Time:** 20 minutes. UWT suggested duration for setup, one full inning per side, and debrief.
**People:** 8 to 20. Two equal teams of 4 to 10 players; odd numbers rotate as scorekeepers or hoop judges.

## Choose this exercise

**Purpose:** Practice collaborative sorting, spatial role allocation, and rapid physical coordination under time pressure.
**Use it when:** Use in an open indoor gymnasium or outdoor field when a group wants an energetic, competitive running game focused on tactical division of labor.
**Skip it when:** Skip when the venue lacks open running space, when physical running is inaccessible or unsafe for the participants, or when quiet cognitive work is required.

## Materials and tools

- 16 tennis balls labeled clearly with permanent marker from 1 to 16
- 4 hula hoops labeled with target ranges: 1-4, 5-8, 9-12, and 13-16
- 1 bucket or basket to hold the 16 balls between turns
- 1 flip chart or scoreboard with marker to track laps

## Before participants arrive

1. Substantial physical setup required: set four hula hoops in a large diamond layout matching baseball bases, spaced roughly 15 to 20 meters apart.
2. Label hoop 1 (home base) for balls 1 to 4, hoop 2 (first base) for balls 5 to 8, hoop 3 (second base) for balls 9 to 12, and hoop 4 (third base) for balls 13 to 16.
3. Place the 16 marked balls in a bucket near hoop 1.

## Say this to open

Welcome to Think Ball. We have two teams: Batters and Fielders. Batters stand in single file behind hoop one. When it is your turn, scatter all sixteen balls into the field, then run laps around your standing line to score points. Fielders, gather the balls and sort them into the four base hoops by number: one to four in hoop one, five to eight in hoop two, nine to twelve in hoop three, and thirteen to sixteen in hoop four. When all sixteen are sorted correctly, call STOP.

## How to run it

### 1. Set teams and explain rules (3 minutes)

Divide participants into two equal teams. Designate Team A as batters and Team B as fielders. Team A lines up single file behind hoop 1. Team B scatters across the field. Deliver the opening script and confirm both sides understand the target hoop numbers.

### 2. Play Team A batting round (6 minutes)

Batter 1 dumps the 16 balls into the field and runs laps around Team A's line. Team B collects and places balls into the four assigned hoops. When all 16 balls sit in correct hoops, Team B calls STOP. Record completed laps. Reset the balls and repeat for remaining batters on Team A.

### 3. Switch sides and play Team B batting round (6 minutes)

Swap team roles. Team B lines up behind hoop 1 as batters. Team A scatters across the field as fielders. Run the exact sorting and running sequence for Team B's batters. Record completed laps on the scoreboard.

### 4. Tally scores and debrief (5 minutes)

Sum the total laps scored by each team to declare the game result. Gather both teams at the center. Ask two participants from each team to share how their coordination, sorting tactics, and communication evolved during play.


## Debrief questions

- What retrieval strategy did the fielding team use to sort the numbers quickly?
- How did communication change between the first batter and the final batter?
- Where was time lost or gained during the sorting process?

**Finished output:** A completed game with recorded lap scores comparing team sorting and running performance.

## Remote

This active physical tag game cannot run online without becoming an entirely different digital puzzle. If working remotely, run a digital sorting relay instead: break groups into breakout rooms and have them sort 16 shuffled digital numbered cards into four labeled quadrants on a shared digital whiteboard under timed conditions.

## Hybrid

Hybrid delivery is not recommended. Remote participants cannot participate safely or fairly in a physical running and fielding game. Keep all active participants in person, or switch the entire group to a digital sorting alternative.

## Access and participation choices

- Participants may choose roles such as runner, fielder, static hoop verifier, or official scorekeeper.
- Runners may fast-walk rather than sprint.
- Fielders can specialize in relaying balls by passing rather than running long distances.

## If the session gets stuck

**Balls get placed in the wrong hoop, but the fielding team calls STOP anyway.**

Appoint one hoop verifier per hoop or act as referee. If an incorrect ball is found, call 'Play on!' The batter keeps running until the fielding team corrects the error.

**Batters throw all 16 balls right at their feet, making retrieval too fast.**

Clarify during setup that balls must be thrown past a minimum boundary line, such as 5 meters out into the field.


## Terms used here

- Batting side: The team running laps around their own line to accumulate points.
- Fielding side: The team collecting and sorting numbered balls into the four designated base hoops.

## Sources and adaptation

Observed in Playmeo records; attributed by Playmeo to Mark Collard.

Retained core mechanics from Mark Collard / Playmeo source records: 16 numbered tennis balls, 4 base hoops with four numbers each, batters lapping their team line, and fielders calling STOP upon completion. UWT added explicit diamond layout dimensions, safety options, an adaptation boundary rule, scorekeeping structure, and a structured debrief.
