Number Decomposition vs Zerlegen

LEARN MATH – WITHOUT COUNTING Many children learn arithmetic by counting. That is tedious and often the start of later difficulties with math. This app begins exactly where true understanding develops after quantity–number correspondence: with the automation of number bonds up to 10. Children learn how numbers are structured and can solve addition and subtraction tasks safely, quickly, and from memory. No counting, no frustration, with visible success. HOW IT WORKS • Example: 8 = ? and 3 • One part is given, the other is added via drag & drop • Correct? → reward and progress • Wrong? → gentle feedback and repeat • Only fast, correct answers (under 5 seconds) count as “known by heart” MADE FOR CHILDREN – EVEN WITHOUT READING • Intuitive operation with number tiles and structured quantity images (dice, fingers, dots, and more) • Four child-friendly animal avatars: panda, dolphin, cat, dog • Each correct task colors the avatar more • Learning progress is always visible and motivating FOCUSED LEARNING INSTEAD OF A GAME APP • Reduced sounds and calm, clear visuals • No distracting effects, no flashy colors • Clear didactic structure: not a game, but a real teaching and learning app PEDAGOGICALLY SOUND – RESEARCH-BASED • Leitner learning system with spaced repetition (boxes 1–4) • Didactic reduction: only meaningful decompositions, no swapped pairs, no zero • Structured quantity images strengthen number sense and understanding • Error-oriented learning: incorrect tasks are deliberately repeated • Progress per avatar is transparent – also for parents and teachers SAFE AND AD-FREE • No ads • No in-app purchases • Works offline – ideal for on the go • One-time purchase, permanent use DOWNLOAD NOW – MAKE MATH SIMPLE With this app, your child becomes a master of number bonds: playful, visually structured, and sustainable. Ideal for preschool, first grade, or home practice – without distractions and with full focus on what matters.

Zerlegen hilft Kindern, Zahlen besser zu verstehen: Mengen am Zehnerstreifen legen, erfassen, zerlegen und wieder zusammensetzen ist die Grundlage für sicheres Rechnen (Teil-Ganzes-Verständnis). • Für Nichtleser gestaltet: klare Bilder, gesprochene Anleitungen, keine Werbung, keine Ablenkung • Vielfältige Übungen vom Mengenlegen bis zur Aufgabenfamilie • Neun Spiele zum Automatisieren der Zahlzerlegungen, zum Beispiel Verliebte Zahlen, Häuser bauen und Bushaltestelle • Fortschritt pro Kind (Kompetenzraster), mehrere Profile, komplett offline • Fachdidaktisch fundiert Zerlegen ist für den Anfangsunterricht entwickelt und eignet sich für zu Hause wie für die Schule.
