✂️ Cardboard Prototype Build

Using cardboard, tape, recycled materials, craft sticks, markers, and index cards, mixed-age teams build one quick model, sign, tool mock-up, or set of story panels from their chosen idea. The teacher pauses mid-build for a short test routine where students show the prototype to 2 peers, receive feedback, and revise one part immediately. Students add labels, arrows, or sequence boxes so others can understand the problem and solution.
