Description

Recheniehrmittel mit Zählbahn. Die bisher im Gebrauch befindlichen Rechenmaschinen verwenden zu ihrem Aufbau als notwendig Stangen, Latten oder ganze Gestelle. Dies macht ihre Handhabung umständlich und schwerfällig.Calculation aids with counting track. Those currently in use Calculating machines use rods, slats or whole bars as necessary for their construction Racks. This makes them cumbersome and cumbersome to use.

Diesen gegenüber ist der Träger der vorliegenden Erfindung nach Art eines Seiles, Schlauches, einer Kette oder Schnur usw. unstarr, und er läßt sich daher sehr einfach ausspannen.In relation to these, the carrier of the present invention is entitled according to Art of a rope, hose, chain or cord, etc., unstable, and he lets himself go therefore relax very easily.

Der Träger besteht beispielsweise aus einem der Größe der Einheiten und dem zur Verfügung stehenden Raum entsprechenden Seil. Auf diesem laufen too gleichartige Kugeln in verschiedenen Farben, z. B. zehn schwarze a und zehn rote b. Die methodischen Einheiten sind durch handbreite Tafeln c und weiße Ringe d markiert, die mit den Kugeln am Seil laufen. Dieses selbst wird zweiteilig an Haken aufgehängt, die zu dem Zweck an den Seitenwänden angebracht sind. Der gerade benötigte Teil des Seiles hängt quer vor der Klasse. Der übrige wird an der Seitenwand befestigt oder kann herunterhängen. So sind dem Kinde die nicht benötigten Zahleneinheiten völlig aus dem Auge gerückt.The carrier consists for example of one of the size of the units and the rope appropriate to the space available. Run on this too similar balls in different colors, e.g. B. ten black a and ten red b. The methodological units are marked by panels c and white rings d, as wide as a hand, who run with the balls on the rope. This itself is hung in two parts on hooks, which are attached to the side walls for this purpose. The part you just need the rope hangs across in front of the class. The rest is attached to the side wall or can hang down. So the child does not need the number units completely out of sight.

Die Handhabung und Anwendung des Rechenseiles erfordert in methodischer Hinsicht keine Einarbeitung. Die Abgrenzung der methodischen Gruppen ist ebenso einfach wie übersichtlich. Das Rechenseil ist überall verwendbar wegen seiner Biegsamkeit. Es ist leicht transportfähig und montierbar.The handling and application of the arithmetic rope requires methodical Respect no training. The delimitation of the methodological groups is the same simple and clear. The computing rope can be used anywhere because of its flexibility. It is easy to transport and assemble.
