On most whiteboards, the pages are held together by four magnets. Four, because with three, one corner curls up. Someone walks by, catches it with their sleeve, the magnet falls, and the page flies after them. Someone else copies the text directly onto the board with a dry-erase marker to avoid fumbling with the magnets, but then it's impossible to read, the text changes, and copying the information requires more time. Sometimes the pages are laminated or taped. Each station develops its own method, and together they don't lead to order.
