Zahlenschatzjagd การศึกษาขั้นพื้นฐาน แอป สำหรับ Android คำอธิบาย
Zahlenschatzjagd (number treasure hunt) lets children in their first two school years practise maths on their own – offline, without ads and without a single permission. It is made for children who cannot read yet: pictures and a voice that reads everything aloud show the way.
The app and all its texts are in German only. It follows the maths curriculum for primary schools in North Rhine-Westphalia and speaks to German-speaking children and parents.
Exercises
- addition
- subtraction
- multiplication and division up to 10, 20, 50 or 100
- doubling
- number walls
- number bonds to 10
- comparing numbers
- finding neighbouring numbers
A treasure chest fills up for each exercise, from bronze to platinum.
For parents, behind a small sum or a PIN: what a child practised recently and how confident it is, a practice calendar, which exercises a child may use, sound and read-aloud settings, and a backup file of all progress for moving to a new device.
Several siblings can share one device, each with their own profile and progress. No permissions, no tracking, no account – all data stays on the device.
