A school class in Slovakia used mathedu.online for 2 hours: unit conversions, grade 5. ~500 problems per kid, 95 % correct. Nobody told me. I don't know which school it was, and with cookieless analytics I never will. So this weekend I shipped classes for teachers: – printed tests with a per-student code + QR – enter paper results as ✓ / ✗, the site does the math – gradebook export (CSV) – invite parents with one link Practice stays free, no ads, no cookies. https://mathedu.online/?utm_source=nostr&utm_medium=social&utm_campaign=class-in-the-wild
