LensQuest
A window was left open, a coat went missing, a crash rang out - and four kids each tell you what happened. Nobody's lying, but they stood in different places, so their stories don't all match. Which two agree? Which two can't both be true? Who's claiming something they couldn't possibly have seen? Read across all four, drop the guesses, keep what the real witnesses agree on - and write the fifth account: what actually happened. A tiny, deterministic point-of-view engine, no internet. Ages 9-14.

Meet the cast
LensQuest's crew ARE four ways of seeing the same event - the cast IS the curriculum: each character IS one narrator's vantage, and reading across them teaches how corroboration works. Ravi stood at the window bench, so his account of who opened the window and the coat colour is a real observation. Mei was by the coat hooks near the side door, so she saw the coat and the door - but with her back to the window, her claim about who opened it is a guess. Sam watched from the hall doorway, so he saw the door and heard the crash, but the coat was too far to make out. Nella was painting in the far corner facing the wall, so she could only hear the hall - everything else she says is a guess, even when she happens to be right. Lens, the mentor, is the calm reader who never asks who is telling the truth, only who could actually see it and whether they agree. Nothing leaves the device.
Ravi
Saw it for himself — sat facing the window and the coat hooks, so his account of both can be trusted
Mei
Half saw, half guessed — saw the coat and the door, but only guessed about the window behind her
Sam
The narrator in the hall doorway - a real witness to the door and the crash, but too far to judge the coat's colour, so that claim is a guess
Nella
The narrator in the far corner facing the wall - could only hear the hall, so every other claim is a guess, teaching that being right by luck is not the same as knowing
Lens
Vantage, not volume — a detail is settled only when two people who could see it agree
