Description
Hilfsmittel für den Rechenunterricht. Die vorliegende Erfindung betrifft ein Hilfsmittel für den Rechenunterricht. Sie bezweckt die Ermöglichung der Selbstkon trolle der Resultate von auf den Tabellen ge- stellten Aufgaben. Es ist zu diesem Zwecke mit einem elektrischen Signal versehen. Das Granze ist lehrreich, anregend und intereesa-nt.
Auf beiliegender Zeichnung ist ein Aus- des Erfindungsgegenstandes für -den elementaren Reehenunterrieht näher erliiutert, und zwar zeigt Fig. 1 das Hilfs t' für -den Rechenunterricht in einer An sieht. Fig. 2 zeiht die Kontakttafel von oben.
Fig. 3 und 4 stellen einen Quer- und einen hiirigssehnitt. dar. Fig. 5 zeigt die Kontakt tafel von unten, und Fig. 6 ist eine Drauf- sieht: auf das Innere des Gehäuses.
Wie aua der Zeielmung ersichtlich ist, be- ste.ht das. Hilfsmittel für den Rechenunter- richt aus einem Gehäuse GH mit Kontakt organen 1i, elektrischem Glühlämpchen G, Batterie B, sowie \1 Prüfkabeln mit Steckern P un d auswechselbaren Rechnungs.tabel.len T,
mit Konta.ktloehungen KL.
Das Ausführungsbeispiel zeigt eine auf- ,-elegt.e Rechnungstabelle T zum Multiplizie- I'rIn mit karierten Feldern, welche Aufgaben rnd Resultate enthalten. Jedem dieser Fel der ist ein Kontaktorgan K und eine Kon- taktlochang KL zugewiesen. Wegen besserer (.")ersicht werden,
die Felder in verschiedenen Farben hergestellt, und zwar die Aufgaben felder in griin. rot und weiss und die Lösung#- Felder in gelb. Die Fig. 1 stellt,die Aufgabe 5' X 8 dar mit dem Resultat 40. Das eine Prüfkabel steckt in der Kontaktlochung KL im Farbenfeld der Aufgabe = 5 X 8, und da,s andere Prüfkabel steckt im Farbenfeld des Resultates. = 40.
Die Kontaktorgane sind so untereinander elektrifa"h leitend verdrahtet (siehe Fig. 5), dass bei der Richtigkeit des Resultates in bezug auf die .geteekte Auf gabe das Lämpchen G aufleuchtet (siehe Fig. 4).
Es sind mehrere auswechselbare Tabellen; T mit elementaren Rechnunbaufgaben zur Multiplikation, Division, Addition und Sub traktion vorhanden.
Die jeweils aufgelegte Rechnungstabelle T wird durch Führungs stifte F und dem Lämpchen G festgehalten. Die Kontakte K sitzen in der Kontakttafel <I>I7</I> fest und sind unten miteinander verdrah tet, wie dies Fig. 5 mit einigen Drahtverbin dungen D zeigt.
Die Verbindung der Prüf kabel P zur Lämpchenfa@ssung L und der Batterie B wird in Fig, 6 verawehaulicht. Die Batterie B wird. mit 2' Haltern <I>BH</I> fest- geklemmt.
Tools for arithmetic lessons. The present invention relates to an arithmetic teaching aid. Its purpose is to enable self-control of the results of the tasks on the tables. For this purpose it is provided with an electrical signal. The border is instructive, stimulating and interesting.
In the accompanying drawing, an embodiment of the subject matter of the invention for elementary education is explained in more detail, namely, FIG. 1 shows the auxiliary t 'for arithmetic instruction in one aspect. Fig. 2 shows the contact board from above.
3 and 4 show a cross section and a rear section. Fig. 5 shows the contact board from below, and Fig. 6 is a plan view: of the interior of the housing.
As can be seen from the drawing, this is the best. Aid for arithmetic lessons from a housing GH with contact organs 1i, electrical light bulb G, battery B, and test cables with plugs P and exchangeable billing table. len T,
with KL.
The exemplary embodiment shows an on-, -elegt.e calculation table T for the multiplier with checkered fields which contain tasks and results. Each of these fields is assigned a contact element K and a contact hole length KL. Because of better (. ") Be seen,
the fields are made in different colors, and the task fields in green. red and white and the solution # - fields in yellow. 1 shows the task 5 'X 8 with the result 40. One test cable is in the contact hole KL in the color field of the task = 5 X 8, and there, the other test cable is in the color field of the result. = 40.
The contact organs are wired to one another electrically conductive (see Fig. 5) that when the result is correct with respect to the .getekte task, the lamp G lights up (see Fig. 4).
There are several interchangeable tables; T with elementary arithmetic tasks for multiplication, division, addition and subtraction available.
The invoice table T that is placed in each case is held in place by guide pins F and G lamp. The contacts K sit firmly in the contact panel <I> I7 </I> and are wired together below, as Fig. 5 with some wire connections D shows.
The connection of the test cable P to the lamp holder L and the battery B is shown in FIG. The battery B will. clamped with 2 'brackets <I> BH </I>.
