How it works

Section titled “How it works”
  1. Open the Lesson page (scan the QR code at the end of the Episode, e.g. chenning.app/4.1.3).
  2. Watch the Episode with your child, then press Start Practice.
  3. Your child serves customers in the sisters’ shop by dragging Value Tokens, about 10 minutes. A wrong answer gets a hint naming one of the four steps (Say it, Think, Work it out, Check) and another try.
  4. Come back three days later for the Mastery Check. 4 of 5 right earns a Sticker.
  5. Hold Grown-ups in the Lesson page’s top corner for one second (or hold Space/Enter on the button). The Grown-up Page shows mastered Lessons, the step needing the most Hints and its home tip, plus dated Practice and Mastery Check results on this device. Observe the Episode’s Think Pauses and Activity yourself; they are not recorded automatically.
