Zahlzerlegung

Discovering maths through play

Zahlzerlegung makes learning the basics of maths child’s play. The app helps children build a deep understanding of numbers – the most important foundation for every further mathematical skill.

Why number decomposition?

Breaking numbers apart is a fundamental mathematical skill. Children who understand that 7 = 3 + 4 or 10 = 6 + 4 have a much easier time later with mental arithmetic, word problems, and understanding larger numbers.

Who is the app for?

• Primary school children (years 1–2) to practise and consolidate
• Parents for playful support at home
• Teachers as a digital complement to lessons
• Preschoolers for a gentle start into the world of numbers

How it works

1. Practise in the number range up to 10
2. Solve interactive decomposition exercises
3. Collect stars and track your progress
4. Celebrate your successes with fun animations
