Classroom Noise Monitor🍁 Thankful Tree 🍁
When the class is quiet, a new thankful leaf unfurls on the tree, each showing something to be grateful for. When it gets too loud, the wind shakes the branches, and if it stays loud, the leaves start to blow away!
Class goal: Fill the tree with all nine thankful leaves before the lesson ends!

How Thankful Tree works
1. Plant the tree
Choose a lesson length, press Grow the Tree, and allow the microphone. The monitor listens for a moment to learn how your room sounds when it is calm.
2. Quiet grows thankful leaves
While the class is quiet, nine big maple leaves unfurl on the tree one by one, each painted with something to be grateful for: family, friends, pets, books, sunshine and more.
3. Noise shakes the branches
Too much noise sends a gust through the tree, and if it stays loud, thankful leaves blow away and have to grow back. Tip: each time a new leaf appears, ask a student to share one thing they are thankful for.

Yes, sustained noise has consequences here. If the room stays loud, the wind blows thankful leaves off the tree and the class has to grow them back. A few seconds of calm stops the damage.

Thankful Tree works well from preschool through grade 5. The picture leaves need no reading, and the tree pairs naturally with gratitude activities in November.

Your computer is probably listening to the wrong microphone. Interactive whiteboards often take over as the default mic when they're connected. During a session, open the settings (the tune icon in the top right) and pick your computer's built-in microphone. The choice is remembered for future sessions.
