For grown-ups
SlateForge turns your child into the teacher. Scrawl, a young crow, works a fraction sum or an equation line by line in fast slanted ink. Exactly one line is where the working first goes wrong, and each wrong line is a named, common misconception: adding the bottoms, forgetting to flip when dividing, moving a number without changing its sign, multiplying only the first term in a bracket.
Your child taps that line, picks one of three handwritten fixes, and tells Scrawl the rule. There are sixty slips. Every line, every fix and every wrong option is checked by an exact maths engine (fractions are kept as fractions, never rounded), so nothing on screen is a trick.
There is no Solve button. On the "Your working" page your child works their own sum or equation, and each line only ever gets a mark: follows, doesn't follow yet, or solved. The app never writes the answer to your child's own problem.
Whose pen? The meter shows how much of the fixing was your child's. A nudge points to where to look and costs a little of the pen; it never shows the fix. Nothing needs an account or the internet, and progress stays in this browser.
What it never does
- No accounts, no ads, no tracking — anything kept stays on this device.
- No streaks, timers to beat, points to chase or leaderboards.
- No chat, and nothing anyone types is sent anywhere.
