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.

# Foursquare

Four active players hit a playground ball between marked squares following a single bounce rule, rotating through ranks while waiting players queue to enter.

**Time:** 15 minutes. Playworks suggests 10 minutes or more; 15 minutes provides orientation, steady play rotations, and a quick review.
**People:** 4 to 12. Four active court players in individual squares, with remaining participants in a single waiting line.

## Choose this exercise

**Purpose:** Practice hand-eye coordination, quick reaction, and rule-governed court rotation in an active physical game.
**Use it when:** Use during active outdoor or gym energizers, recess blocks, or camp activity sessions where participants want structured physical movement.
**Skip it when:** Skip when the meeting requires seated intellectual work, lacks clear flat ground, or when group members cannot participate in moving ball play.

## Materials and tools

- 1 standard rubber playground ball (8.5 inch) per court
- Sidewalk chalk or floor tape to mark the court
- 1 tape measure

## Before participants arrive

1. Mark a 10 foot by 10 foot court on smooth, flat ground.
2. Divide the court into four equal 5 foot by 5 foot squares labeled 1, 2, 3, and 4 (or A, B, C, D).
3. Mark a 1.5 foot by 1.5 foot service box in the outer corner of Square 1 (or Square D, depending on your court's designated server rank). Keep the ball at the server box.

## Say this to open

We will play standard Foursquare. Four players occupy the squares labeled 1, 2, 3, and 4. Everyone else forms a waiting line beside square 4. The server drops the ball once in their box and strikes it underhand into another square. Let the ball bounce once in your square, then strike it with your open hand into someone else's box. If you miss, catch the ball, hit it out of bounds, or let it bounce twice, you step to the waiting line, and the line moves up. Let us assign our first four players.

## How to run it

### 1. Explain court layout and basic rules (3 minutes)

Walk the group along the court perimeter. Point out squares 1, 2, 3, and 4. Explain the single bounce requirement: the ball must bounce exactly once in your square before you hit it, and you must hit it with an open hand without catching, holding, or carrying. Explain the rotation: whenever a player faults, they go to the back of the waiting line, the person at the front of the line enters square 4, and court players slide forward toward square 1.

### 2. Demonstrate serve and legal hit (2 minutes)

Demonstrate the serve from the server's square: drop the ball once into your own square and hit it on the rise into any opposing square. Keep feet inside the service area during the serve. Have one volunteer return the ball after a single bounce to show a legal rally hit.

### 3. Run continuous rotation play (8 minutes)

Place four players in the squares and line up the rest. Start the game. When a fault occurs (ball lands on line, goes out of bounds, bounces twice, hit before bounce, or carried), the faulting player leaves for the waiting line. Remaining court players advance to fill the empty square, and the next person in line steps into square 4. Facilitator monitors lines and calls clear faults neutrally.

### 4. Conclude and review gameplay (2 minutes)

Call time on the court. Gather players around the court boundary to review calls and observe tactical adjustments made during rallies. Offer 2 or 3 quick volunteer reflections.


## Debrief questions

- What strategy helped you keep rallies going when incoming shots bounced close to the boundary?
- How did the group handle close calls on lines or double bounces?
- What adjustments made returning difficult serves easier?

**Finished output:** Continuous rounds of four-person court play completed with all participants rotating through active play or waiting queue.

## Remote

Foursquare is an in-person physical ball game and cannot be played virtually without turning into an unrelated software game. For online groups needing a quick coordination energizer, run a verbal word-association circle game instead.

## Hybrid

Foursquare requires physical court presence. Remote participants cannot share the physical court. Run this exercise only with an entirely co-located in-person group.

## Access and participation choices

- Offer the catch-and-drop variation for participants needing slower pace: allow catching the ball once and dropping it to bounce before hitting it forward.
- Participants may choose line referee, score recorder, or ball retrieval roles instead of active court running without needing to explain reasons.

## If the session gets stuck

**Disputes break out over whether a ball landed on a line or out of bounds.**

Enforce standard playground rule: lines are out, and if players disagree, the server replays the point once.

**The waiting line grows too long, causing participants to wait more than 3 minutes.**

If group size exceeds 8 players, mark a second 10x10 court so two independent games run in parallel.


## Terms used here

- Service box: A small marked box inside the server's square where the server must keep their feet while serving.
- Carry: An illegal shot where a player scoops, lifts, or catches the ball instead of hitting it cleanly.

## Sources and adaptation

Observed in Playworks Game Library documentation for playground Foursquare.

Retained the traditional playground foursquare rules and court dimensions recorded in Playworks documentation (single bounce rule, open hand hit, rotation from line into highest-numbered square). Discarded old erroneous metadata categorizing foursquare as an introspective reflection exercise. Added facilitator scripts, court management steps, capacity bounds, and access adjustments.
