Proof Builder
Proof Builder becomes a guided simulation lab where learners make predictions, act, revise, transfer, and produce evidence.
Playable World missions
Pick one mission. Follow the guide. Submit evidence.
Released missions come first: a plain link, the catalog, and campaign links open those. Earlier missions stay listed for existing classroom links and recorded evidence.
