ZERO+ 1 UNDERSTANDING SYSTEM DECIMAL NUMBERING QUERCETTI 2361

Zero +1 is a new educational aid made to facilitate understanding of the decimal numbering system. It transfers the abstract nature of the numbering system to the plane of sensory experience. Each gear corresponds to a unit of measurement (units, tens, hundreds) that can also be changed; the child will have to rotate the gear a number of times equal to the number to be counted. The number that will appear on the red arrow will be the result of his operation. If the first gear (right) is rotated more than 10 times, it will cause the second gear (middle) to rotate one position, resulting in the tens click.
Zero +1 is an innovative educational aid designed to facilitate understanding of the decimal numbering system in a sensory and experiential way. This tool transforms the abstract concept of numbers into a tangible experience.
Zero +1 consists of gears that represent the units of measurement (units, tens, hundreds). By turning the gears, the child will have to count the number of rotations required. The result will appear on the red arrow. If the first gear is rotated more than 10 times, the tens click will be activated, and so on.

This tool is useful both at home and at school, with the goal of encouraging the acquisition of abstract concepts related to the decimal numbering system. Due to its sensory nature, Zero +1 allows children to understand the meaning of numbers in an interactive and engaging way.

Suitable for children ages 6 and up, Zero +1 is a simple yet ingenious tool that promotes number learning and facilitates early math operations such as addition and subtraction.

The size of Zero +1 is about 27x16 cm, making it convenient to use and carry. It is a fun and stimulating way to introduce children to the world of numbers and develop their math skills in an intuitive way.
