Put the music on, tidy up together, and when the song ends, the room is done. That’s the idea behind my tidy-up timer songs. Each song lasts 3, 5, 10, or 15 minutes, so the song itself is the timer. In the video, a messy children’s room gets tidier one toy at a time until it sparkles in the last ten seconds. Kids can see how far along they are and that the end is coming.
