Stump the Grown-Up

Included in The Whole Shelf

Children spend most of their time being asked questions. This turns it around.

Forty cards, cut out and kept in a pocket or a tin. The child picks one, reads the question out loud, and the grown-up has to guess before the answer gets turned over. Then somebody keeps score.

The questions are the sort that sound easy until you try to answer them:

  • Why do tree trunks grow round instead of square?
  • Why does bread go hard when it's stale, but biscuits go soft?
  • Why do onions make you cry?
  • Why does ice float instead of sinking?
  • Why is the sea blue when water from a tap is clear?

Every answer is on the back of its own card — short enough for a child to read aloud, and correct without being simplified into something untrue. Where scientists genuinely aren't certain, the card says so. That's a better lesson than a confident wrong answer.

There are blank cards at the back for questions of their own, and a best-of-ten scorecard for settling it properly.

These are questions about the things this book explores — the everyday world, plants, weather, water, light. They stand on their own, so nobody has to go hunting through the book mid-game.

What you get: 40 cards across 12 printable sheets · A4 · instant digital download · yours to keep. Print double-sided, flipping on the long edge, and the answers land on the back of the right cards. Instructions included.


The Sage & Page Note

We don't believe every book deserves your attention. We believe the right book can stay with you for years.

That's why every title we recommend has earned its place through our curation process — not because it's popular, but because we believe it offers lasting value.
