Free-roam browsing of every learning path by Theme World, voice search, progress rings, nothing ever locked. A child who wants volcanoes today gets volcanoes today.
The six Theme Worlds are the shelves.
Search meets a five-year-old where they are.
A child can see what they've explored, without a number.
Exploration is the point of the PYP, not a reward for compliance.
