When any player commits a fault, all four court players advance one position and the waiting line enters square D. **Time:** 15 minutes. Playworks notes 10 minutes or more. 15 minutes provides setup, practice, multiple rotations, and a brief wrap-up. **People:** 4 to 16. Court of 4 active players plus a single queue of waiting players. ## Choose this exercise **Purpose:** Give a group a physical, fast-paced rotational ball game to practice turn-taking, gross-motor tracking, and rapid rule enforcement. **Use it when:** Use during active outdoor or gym breaks when participants need high physical movement and quick rotational turns. **Skip it when:** Skip during seated workshops, small indoor rooms, or when physical agility, bouncing balls, and sudden lateral movement are unsuitable. ## Materials and tools - 1 standard 8.5-inch playground bouncy ball per court - Chalk or court painter's tape to mark boundaries - Pre-marked court: 10 feet by 10 feet exterior box divided into four 5 feet by 5 feet squares labeled A, B, C, and D ## Before participants arrive 1. Mark a 10 by 10 foot square on flat pavement or gym floor using chalk or tape. 2. Divide the square into four 5 by 5 foot quadrants. 3. Label the squares clearly: A, B, C, and D. 4. Designate a waiting queue line outside square D, keeping players at least 5 feet back from the court perimeter. ## Say this to open We are playing Blank Slate Four Square. Four people stand inside the squares, and everyone else forms a waiting line near square D. If you are in square D, you serve by dropping the ball and hitting it with your hand into another square. The ball must bounce once in your square before you hit it, and bounce once in the receiver's square. If anyone makes an error, that round ends. The person in square A goes to the back of the line, everyone else advances one square, and a new player steps into square D. ## How to run it ### 1. Explain court layout and fault rules (3 minutes) Walk participants through the court. Point out squares A, B, C, and D. Explain the rotation order: D moves to C, C moves to B, B moves to A, and A rotates out to the waiting line. Clarify the five fault conditions: the ball lands on a line, goes out of court bounds, bounces twice in one square, is caught or held, or is struck before it bounces. ### 2. Demonstrate serve and rotation (3 minutes) Place four volunteers in the squares. Have the player in square D demonstrate a bounce-serve into square B. Have square B hit it to square C. Intentionally simulate a ball bouncing twice. Walk the group through the resulting rotation: square A exits to the end of the line, B moves to A, C moves to B, D moves to C, and the next person from the queue enters square D. ### 3. Play rotational rounds (7 minutes) Begin continuous play. The incoming player in square D serves each time. Play continues until a fault occurs. When a fault happens, announce rotation immediately. The player currently in square A exits to the waiting line, all active players shift one square toward A, and the front person in line enters square D. Repeat continuous serves. ### 4. Cool down and debrief (2 minutes) Call time. Bring all participants together off the court. Ask two quick debrief questions, taking two or three short observations from the group. ## Debrief questions - How did the rule of rotating after every fault change the pressure on the person who made the error? - What strategies helped your square keep the rally going versus ending it quickly? **Finished output:** Completion of multiple continuous rotational rounds across all participants. ## Remote This is an in-person, kinesthetic ball game that requires physical court space and cannot run online in this form. For a remote team-sequencing activity, substitute a word-association or prompt-chain game such as Word Association Circle, where participants pass turns alphabetically or in a fixed grid order. ## Hybrid Hybrid play is not feasible for this active physical court game. Remote participants cannot share the physical ball court. Run an online alternative for a fully remote cohort, or ensure all hybrid members meet in person for this session. ## Access and participation choices - Participants may choose active court play, queue referee, scorekeeper, or cheer positions without needing to disclose physical limits. - Players with reduced mobility can play using a larger, slower-bouncing foam ball or catch-and-toss modifications by group agreement. ## If the session gets stuck **Disagreements occur over whether a ball hit a boundary line.** Lines are out. If a call is contested, give the call immediately to the first person waiting in the queue to serve as referee, or replay the serve once. **Queue is too long and waiting players lose attention.** If the group exceeds 10 players, mark a second 10x10 court so two independent games run in parallel with 5 to 8 players each. ## Terms used here - Fault: An illegal hit, out-of-bounds landing, line strike, catch, or double bounce that halts play and triggers rotation. - Square D: The entry square where incoming players from the waiting line start and deliver the initial serve. ## Sources and adaptation Observed in Playworks game library under 'Blank Slate Foursquare' / 'Blank Slate Four Square'. Retained core rules, court dimensions, square labels (A-D), five explicit fault conditions, and entry/rotation rules directly from Playworks. Clarified the four-step facilitator structure, court safety lines, queue boundaries, access roles, and specific timing for workshop settings. Removed old synthetic claims framing this schoolyard game as a relationship-mapping exercise.
