Maths Escape Rooms
Fourteen narrative rooms where the maths is the action, not a toll gate: no question boxes, just instruments you have to set correctly — a dial, a slider, a keypad. Three or four locks a room, fifteen to twenty minutes each, built to end a lesson rather than fill one. Every room has a teacher page with the answers, the hint ladder and the misconception each lock is built around.
