Number Decomposition – Math

No counting – with method

$3.99 · Designed for iPad. Not verified for macOS.

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.

This version fixes issues in the learning system and makes progress more visible. LEARNING SYSTEM • A correct but slow answer used to count as a mistake and reset the task's progress. Now the task simply stays at its current level. • Towards the end, the last two tasks could alternate endlessly without moving on. This is fixed. • Now included: the doubles 2+2, 3+3 and 4+4. Existing progress is preserved. THE DECOMPOSITION IS NOW SHOWN • After a mistake, the quantity visibly splits into its two parts. Children see not only what is correct, but how the number is made up. • Occasionally the decompositions of one number come one after another, making the pattern noticeable. PROGRESS FOR PARENTS AND TEACHERS • Tapping the animal in the settings shows every decomposition with its learning level, so you can see which single task is still shaky. • The tangram animal now gains colour step by step instead of staying grey until a number is fully mastered. • New progress ring for each animal. • A short introduction for parents and teachers on first launch, available again at any time from the settings. EASIER TO READ • Noticeably clearer colours, especially in the pink colour scheme. • The star visibly moves up to the next learning level. • The app now speaks 14 languages. Progress is saved after every answer.
