How it works · How a lesson is built

Every lesson, built the same careful way.

Each GANCE lesson follows ten steps, is staged for its age, and is checked by people before any child sees it.

The ten steps

One lesson, ten moments

Each step uses the method that teaches that moment best, from the school system listed with it. How we chose them →

  1. 1Warm-up reviewSouth KoreaSomething from an earlier lesson, so it isn't forgotten.
  2. 2Key questionJapanOne rich problem to think about before any method is shown.
  3. 3Try it yourselfJapanYour child has a go first. Help comes in small hints, only if needed.
  4. 4See itSingaporeReal objects first, then pictures, then symbols.
  5. 5Jero's mistakeGANCEJero gets it wrong on purpose and your child shows why. Ages 2 to 4 get a gentle “let's listen again” instead.
  6. 6Compare and polishJapanYour child says why one answer works and another doesn't.
  7. 7One change at a timeChinaThe same idea again, with just one thing changed.
  8. 8Solve it aloneSingaporeA short check Jero never helps with, so progress is real.
  9. 9Take it homeFinland · United StatesAn optional activity to do with you, using things you already have.
  10. 10Look backJapanYour child sums up the lesson in one sentence.

Then a real movement break (Finland). At every step, a child can stop. If something a child says sounds unsafe, the lesson stops, a calm screen shows, and a grown-up and a trained GANCE reviewer are told at once.

The same lesson, three ways

For the youngest, each lesson comes in versions for what a child can do at that age. Here is Sound Hunt, our first listening lesson.

  1. 2+From age 2Two body sounds, a clap and a stomp, to copy.
  2. 3+From age 3Three sounds, then finding the picture that made one.
  3. TapTap-alongTap the screen when you hear the sound.

Checked before your child sees it

Six checks, every lesson

A lesson reaches children only after all six. The person who wrote it never signs it off.

  1. 1A written standardEvery lesson is written to the GANCE Curriculum Constitution, the rules every lesson must follow.
  2. 2Sixteen gatesFacts, answer keys, prerequisites, age fit, materials and safety, each checked.
  3. 3A second readerSomeone reads the whole lesson, start to finish, as a child would meet it.
  4. 4An independent certifierA reviewer who didn't write it passes it, or sends it back.
  5. 5Native speakersEach language version is checked by educators who grew up speaking it.
  6. 6A safety testThe lesson's stop is tested before release.
Off the screen

Learning doesn't stop at the screen

Most lessons end with a short activity for home. It is always optional, uses things you already have, and never needs anything bought. Little ones get nothing small enough to swallow, and no activity uses food.
