13-Rod Educational Soroban Abacus

This educational soroban abacus features 13 rods, each with 5 beads, and measures approx. 24.6 x 7 x 1.8 cm (slight variance: 25 x 7.5 x 2 cm). It combines a smooth-finish plastic frame and beads with natural bamboo rods — chosen for durability, acoustic clarity, and sensory engagement. The frame is fully rounded and burr-free for safe handling. An integrated reset button enables quick return to zero after each calculation, supporting structured practice routines. Designed for mental arithmetic development, it facilitates hands-on mastery of place value, number bonds, and operational logic — appropriate for early years through secondary-level reinforcement and adult numeracy improvement.
