Simeonov’s 10-omat

(1 customer review)



The 10-omat is essentially a decimal clock (10 digits) that visually represents numbers from 0 to 99. It can also be used as a mechanical pocket calculator to add and subtract within this range. The 10-omat’s “magical” ability allows children to see, touch, and hear numbers and calculations. It proactively addresses difficulties related to bridging to ten understanding.


Pre-Order now, and receive the very first 10-omats available by the 1st of December!



Available on back-order


Application: Similar to a clock, the 10-omat has digits and both a large and a small hand. While the small red hand indicates the tens place, the large blue hand indicates the ones place. Whenever the ones hand moves clockwise or counterclockwise from 9 to 0 or from 0 to 9, the tens hand automatically advances or retreats one step. There is noticeable resistance when this happens, helping learners understand the counting system and the “magic” of the multiples of 10. It can be used independently or in conjunction with the 100-Net and the 100-Net & 10-omat Book.

Learning Environment: The 10-omat is designed for individual use by learners and can be used in both classroom and home settings.

Variants: The product is available in two variants: using the international numeral system or the Austrian school script. In addition to the regular 10-omat, there is a larger demonstration version that can be used by teachers in the classroom. This version includes an audible sound (“click”) during the tens transition, and can be mounted on the wall or placed on the table using the included stand. Additionally, a digital version of the 10-omat will be available soon.

Availability: The 10-omat can be purchased individually or as a set with the 10-omat demonstration version.

  1. Doris Riegler

    Ein neuer, sehr ansprechender Ansatz, um den 10er-Übergang zu veranschaulichen. Sehr praktikabel!

    Die Schüler konnten die Aufgaben mit dem 100er Netz gut lösen, der Umgang mit dem 10-omat war ansprechend.

    Die Kinder konnten am großen 10-omaten gut orientieren, was bei der Einführung sehr hilfreich war. Auch zur Anschauung und Überprüfung von Aufgaben mit dem 100er-Netz war der große 10-omat gut ein zu setzten.

    Für die Kinder war das akustische Signal des großen 10-omaten ein Highlight.

    Die Schüler haben sehr gerne mit dem 10-omat gearbeitet, haben gerne Aufgaben eingestellt, und selbständig damit weitergearbeitet. Mit Legematerial hat man nach einigen Aufgaben schon einige Schüler verloren, die das Legen ablehnen.

    Der 10-omat ist cool – da muss man nichts wegräumen und kann gleich eine neue Aufgabe einstellen.

    Für die Kinder war es sehr gut zu sehen, dass es nach dem Zehner weitergeht. Keine Sprünge wie bei der klassischen 100er- Tafel.
    Die Sektoren waren hilfreich, um den Aufbau des Hunderters zu verstehen.
