Complete activity
X02 — Repair-display route map, 20 minutes split if wanted. Materials: complete C03/C04, four large cards, paper arrows and words/pointing support. Put ore, alumina, metal and foil on a source-labelled path. On a separate mat model rock components with paper tiles, leaving names unknown. Make a reader note explaining how a making path differs from a component model. A possible ordinary response names the beginning resource and final made product; tiles do not become identified minerals. Ask an actual reader what one arrow means only if available. Keep the original stage sources visible throughout.
