01
Set the footprint
Mark and test the operating footprint. Mark one camera position away from furniture, doors, cables, queues, tools, food, and the main route through a short drop-in window connected to a substitute-led class period. BubbleMatch comes first because its movement can be tested inside the real footprint while a one-sentence explanation and a visible result remains visible.
02
Open the round
Rehearse the exact opening moment. In a short drop-in window connected to a substitute-led class period, the host opens with BubbleMatch because the adult may not know the class routines or room layout; people decide quickly whether an activity feels approachable. The host uses a one-sentence explanation and a visible result, gives one complete turn, and hands the result back to substitute teachers so the activity can provide an active option that is easy to explain and stop through give people an easy first turn. The operating angle is a simple script, visible boundary, and no complicated equipment.
03
Guide the rotation
Assign and rehearse the operator sequence. The host names the first action in one sentence, demonstrates BubbleMatch, invites a voluntary turn, waits for the result, and offers WhackAMole only when the room still supports provide an active option that is easy to explain and stop through give people an easy first turn. Next: WhackAMole or observe; mark the exit.
04
Close or change course
Brief privacy and contingency choices before opening. In a short drop-in window connected to a substitute-led class period, explain the webcam view before play and keep it separate from attendance, purchase, membership, student, health, or contact records. Do not record or share participant images by default; offer a no-camera or watching role to anyone who does not want to appear. If the adult may not know the class routines or room layout; people decide quickly whether an activity feels approachable, pause the station before it interferes with the main purpose of a short drop-in window connected to a substitute-led class period. Switch to WhackAMole or a no-camera explanation, keep the same marked zone, and stop cleanly.
