Abacus: Bead Math turns four classic counting tools into a bright, hands-on way for kids to learn numbers. Slide the colorful beads and a live number appears under the frame, so children see place value, addition and subtraction come to life. FOUR ABACUS STYLES TO EXPLORE • Chinese suanpan (2+5), Japanese soroban (1+4), Ming-style abacus (1+5), and a 10-bead counting frame • Tap or slide a bead to the beam and the number updates instantly • The live readout under the frame turns bead positions into place value kids can see THREE WAYS TO PLAY • Make a number — build the target on the beads • Add — start from a number, then add on the abacus • Subtract — take away, bead by bead (never goes negative) • Three ranges as skills grow: up to 99, 999, or 9,999 MADE FOR FAMILIES • Kid mode with gentle hints and big, easy beads • 100% offline — play anywhere, no Wi-Fi needed • No ads. No in-app purchases. No accounts. No data collected. Ever. • Warm, friendly art and calm sounds • Plays in 11 languages: English, 中文, हिन्दी, Español, العربية, Français, বাংলা, Português, Bahasa Indonesia, Tiếng Việt, اردو Great for ages 4+, classrooms, and Montessori-style hands-on learning. Part of the Math Duel family of kid-friendly, offline learning games.
