🧰 Calm Tool Prototype Lab

Students quickly build a low-fidelity Version 1 calming tool (breathing card set, calm-down flip book, movement routine poster, or fidget model) using paper, crayons, index cards, and tape. They label their tool with at least two stress vocabulary words and state who it is for (e.g., “second graders during math games”). Students practice explaining how the tool helps lower heart rate.
