Classroom Noise Monitor🐌 Snail Race 🐌
When the class is quiet, the snails slide ahead and their sparkly trails stretch toward the finish line. When it gets too loud, the snails hide in their shells and the race stops!
Class goal: Get all nine snails across the finish line before the lesson ends!

How Snail Race works
1. Start the race
Choose a lesson length, press Ready, Steady, Slow!, and allow the microphone. The monitor listens for a moment to learn how your room sounds when it is calm.
2. Calm slides the snails
While the class is quiet, nine numbered snails glide down the garden lanes, leaving sparkly trails behind them and crossing the finish line one by one.
3. Noise hides the racers
Too much noise tucks every snail into its shell and the race stands still, but nobody ever slides backwards. Tip: cheer for a different 'snail of the day' and see how far the class can get it before the bell.
