On-task Otter
A classroom work timer and noise meter where the class earns stars for finishing on-task sessions and spends them dressing up their otter and decorating its house.
Your class looks after an otter that cheers them on during independent work. The teacher sets a work time, and the timer pauses on its own if the room gets too loud. When the class finishes a session, they earn stars to spend on clothes and accessories for their otter and upgrades for its house.
