P01Ongoing project · Number fluency · Two editions
GeoNum
/ˈdʒiː.oʊ.nʌm/Offline practice for the moments when language and large numbers stop flowing naturally.
Starting question
Can adults rebuild number sense as intuition rather than calculation?
The project began with the realization that even years abroad do not create enough repetition with large numbers. GeoNum Global develops English number fluency; the Korean edition 知悟NUM trains large-number reading, mental arithmetic, and exchange-rate estimation. Both are designed for airplane mode.
