Spiral Abacus

A "spiral abacus" for small kids is typically a toy or a developmental tool, rather than a traditional abacus used for complex calculations. It's often referred to as a "bead maze" or a "roller coaster abacus." The primary purpose of this toy is not to teach math, but to help young children develop essential cognitive and motor skills. A spiral abacus is a colorful, often wooden, toy featuring a base with a series of winding, spiral-shaped metal wires. Along these wires are brightly colored beads of various shapes and sizes. The beads are designed to be moved along the twisting path of the wires.
