How children play with it
As soon as children enter the room, they see the traffic light on the wall or table and automatically orientate themselves by it. During quiet work it glows green; as it gets louder, it changes to yellow, then red. The children become aware themselves, put a finger to their lips, whisper. A learning effect that eases adults’ load and fosters self-regulation.
