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 low-noise period connected to a substitute-led class period. SnowTrail comes first because its movement can be tested inside the real footprint while muted feedback, compact play, and a deliberate stop point remains visible.
02
Open the round
Rehearse the exact opening moment. In a low-noise period connected to a substitute-led class period, the host opens with SnowTrail because the adult may not know the class routines or room layout; the activity must coexist with conversation, reading, service, or concentration. The host uses muted feedback, compact play, and a deliberate stop point, 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 offer interaction without making the room louder or busier. 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 SnowTrail, invites a voluntary turn, waits for the result, and offers BubbleMatch only when the room still supports provide an active option that is easy to explain and stop through offer interaction without making the room louder or busier. Next: BubbleMatch or observe; mark the exit.
04
Close or change course
Brief privacy and contingency choices before opening. In a low-noise period 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; the activity must coexist with conversation, reading, service, or concentration, pause the station before it interferes with the main purpose of a low-noise period connected to a substitute-led class period. Switch to BubbleMatch or a no-camera explanation, keep the same marked zone, and stop cleanly.
