Abacus

Multicolored wooden abacus. This is a great guide for teaching the child the basics of mathematics. Naturally, the child will not consider them as complex formulas. They will become for crumbs another toy, with which you can conduct a variety of developmental activities. Just imagine that the number three appears before the crumb in the form of three bright beads that can be rolled back and forth. Or the knuckles will perform the role of a mosaic, from which you can add a pattern.
