Maths word problems where a child first picks the operation and only then works out the answer.
The hard part of a word problem isn't the arithmetic, it's understanding what to calculate. So every answer has two steps: the operation first, then the result. The stories take place in a world the child picks.
What it does
- A problem generator with correct Polish grammar for numbers, genders and objects
- Difficulty adjusts after every round based on the child's results
- Four hosts with moods, points, levels and a badge album
- Read-aloud for children who are still learning to read
- After two wrong answers the solution is shown step by step; mistakes never cost points
- A parent panel, several profiles per device, progress saved without an account
How I built it
Problem content lives apart from the code, so new characters, objects or a whole new language go into one file. An automated test checks more than 5,000 random problems on every change.
