Field of application from the 1st to the 6th grade

Practically developed and tested by Pruefl with active educators.
It consists of a plate printed with the numbers from 1 - 100 with 100 ring-shaped millings, matching wooden box and wooden rings in the 10 Montessori colors for the numbers and black rings for the prime numbers. The material is used for the complex development of the number range up to 100.
The rings can be placed and stacked in a targeted manner thanks to the milled recesses .

The rings always show the printed number. (in contrast when using chips)
100 red chips are also included in the scope of delivery to cover many other jobs in the hundreds.

This enables: the structure of the numbers up to 100 to be clearly displayed, the series of paint to 100 to be laid out, the prime numbers to be worked out (sieve of Eratosthenes), the smallest common multiple, but also the largest common divisor (to be used by multiple assignment of a number with several number rings).
