Who hurts
Parents of 8–14 year olds who were taught a different method twenty years ago.
The problem
The parent can solve the problem and cannot explain it the way the teacher requires, so helping causes an argument and confuses the child.
What you build
Photograph the worksheet. Get the school's current method, step by step, plus the two questions to ask the child instead of giving the answer, and the specific misconception the exercise is probing.
Why now
Curriculum standards are public documents, so the method can be pinned to a real syllabus rather than guessed.
Validate it this week
One WhatsApp group of parents at one school. Answer photos manually for two weeks and count how many arrive after day three.
Why you'd keep winning
Curriculum coverage per region. Getting one country's syllabus exactly right is a real, boring, defensible effort.
The honest risk
Parents will use it four evenings and forget it exists. Retention, not acquisition, is the hard part — usage is inherently bursty.
The prompt is written to make an AI argue with you before it writes code — that first round of pushback is worth more than the scaffold.
