Description

Die Erfindung betrifft ein Rechengerät auf metricher Basis, das, in einfachster Form hergestellt, s s zur Einführung der Anfänger in die l#Whengrundlagen dienen soll.The invention relates to a computing device on metricher base, which prepared in the form einfachster, s s for introduction of the beginner in the l # When bases are used.

Erfindungsgemäß sind in einer nach dein Metermaß eingeteilten Rinne frei bewegliche, farbig gekennzeichnete Zählkörper zur Veranschaulichung von Zahlen und Rechenvorgängen einstellbar vorgesehen. Die Zählkörper bestehen aus quadratischen, i cm breiten Klötzchen, deren Vorderseite farbig ausgeführt ist, so daß durch Umwenden der Zählkörper je nach der jeweiligen Aufgabe farbige oder nichtfarbige Flächen der Zählkörper über der an der Rinne angebrachten Skala sichtbar sind. Zweckmäßig wird die Skala nach besonders kenntlich gemachten "Zehner- und Fünfergruppen eingeteilt.According to the invention are in a trough divided according to your meter measure Freely movable, color-coded counting bodies to illustrate numbers and arithmetic operations adjustable provided. The counting bodies consist of square, i cm wide blocks, the front of which is colored, so that by turning it over the counting body has colored or non-colored areas depending on the task at hand the counting body is visible above the scale attached to the channel. Appropriate the scale is divided into specially marked "groups of ten and five".

Mit der erfindungsgemäß ausgebildeten Rechenrinne lassen sich in einfachster und anschaulichster Weise die für den Anfangsunterricht notwendigen Rechenvorgänge erläutern.With the computing trough designed according to the invention, in the simplest of cases and most clearly the arithmetic operations necessary for the beginning lesson explain.

In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt.The subject matter of the invention is shown in the drawing, for example.

Ein beiderseits abgeschrägter Holzstab i hat in seiner Länge eine durchgellende Rinne 2. Die vordere Abschr'igtitig des I-lolzstal)es trägt eine Zentimeterskala 3, deren Zehner- und Fünfergruppen be-#onders kenntlich gemacht sind. Die Rinne 2 dient zur Aufnahme der Zählkörper 4. Iss sind dies quadratische, i cm . breite, in die- lZinne 2 passende Klötzchen. Eine der zur Ansicht gelangenden Seiten dieser Klötzchen 4 ist besonders gekennzeichnet, etwa durch abstechende Einfärbung, so daß je nach Belieben die farbige oder die ungefärbte Seite der Klötzchen 4 Tiber der Skala 3 erscheint. In der Zeiclinttiig ist die Aufgabe 2 + 3 = 5 dargestellt.A wooden stick i beveled on both sides has a length of one through-gelling gutter 2. The front Abschriftigtitig of the I-lolzstal) it has a centimeter scale 3, whose groups of ten and five are specially marked. The gutter 2 is used to hold the counting bodies 4. They are square, i cm. broad, in the lZinne 2 matching blocks. One of the pages of this that can be viewed Block 4 is particularly marked, for example by a distinctive coloring, see above that depending on your preference, the colored or the uncolored side of the blocks 4 Tiber scale 3 appears. Exercise 2 + 3 = 5 is shown in the diagram.
