pbl-arc

Design a K-12 project-based learning arc: open driving question, authentic audience, 3–5 milestones with just-in-time teaching, process+product assessment, and a public product. Use when a teacher wants PBL, a project brief, inquiry project, driving question, or milestones that teach through the work. Education only, not a generic unit-arc without authenticity, not a single period (lesson-block).
