낱개(일)·십·백 블록으로 수를 직접 만들고, 10개가 모이면 윗자리로 묶으며 자릿값과 십진법을 눈으로 익히는 초등수학 학습 앱이에요. 각 숫자가 나타내는 값을 확인하고, 주어진 수를 블록으로 만들어 보는 도전도 있어요.
About this app
An interactive math educational web app designed to help elementary school children master place value and the decimal system. Users can manipulate visual blocks representing hundreds, tens, and ones to build numbers, automatically regrouping ten smaller units into the next digit. The app also features a place value analyzer to break down digits and an interactive quiz mode to practice building specific target numbers.
Use cases
- Elementary school students learning double- or triple-digit numbers and place value concepts.
- Parents looking for a visual, hands-on tool to teach children how regrouping works.
- Teachers seeking digital manipulatives for smartboards to demonstrate decimal system principles in class.
Features
- Interactive block representation using 100-flats, 10-rods, and 1-unit blocks.
- A regrouping button that bundles 10 ones into a ten, or 10 tens into a hundred.
- An interactive place value explorer showing the exact value of each digit with expanded notations.
- A randomized number challenge mode to test block-building accuracy.
- Real-time Korean phonetic readings and expanded addition formulas.
