Description

SPECIFICATION An improved device for teaching multiplication tables This invention relates to an improved device for teaching multiplication tables.

A multifarious variety of books is available in the prior art for teaching multiplication tables. In the prior art there is also an invention of a multiplication tables game patented in India under the title "A Device For Teaching Multiplication Tables"-Complete Specification No.140531 dated 4th September 1974.

The object of the present invention is to make improvements in the teaching, learning and memorising of multiplication tables. This invention enables to put into practice the principles of the psychology of learning such as interest, observation, impression, concentration and repetition. This invention makes the teaching, learning and memorising of multiplication tables more convenient and easier.

Moreover, the multiplication tables device made as per the present invention is more durable and economical. This invention has distinct advantages over the aids in the prior art for teaching, learning and memorising multiplication tables.

The present invention of An Improved Device For Teaching Multiplication Tables consists of a set of sheets of any rigid or semirigid material such as paper-board, plastic, metal or the like material. Multiplication tables in any language are printed on the inner pages of this set of sheets. Only one multiplication table is printed on one such inner page. The two outer pages on the front and the reverse sides of this set of sheets are not printed with any multiplication tables. This set of sheets is held together with a fastener-cumpivot made of any material such as plastic, metal or the like material. On this fastenercum-pivot the sheets of the set can be moved by rotation. The foregoing device is illustrated in Fig. 1 in the accompanying drawings.

The purpose of the present invention is served by using it in the manner described below. This method of operating the invention enables to put into practice one of the most important principles of the psychology of learning, viz., concentration. As can be seen from Fig. 2 in the accompanying drawings, teaching, learning and memorising multiplication tables with the aid of this invention do not require much skill. For example, multiplication table of 9 is required to be learnt from the device illustrated in Fig. 1 in the accompanying drawings.In this case, all sheets above the sheet containing the multiplication table of 9 have to be moved and brought together in downwards position under the top sheet which has no multiplication table on its outer page and all other sheets have to be rotated and brought together in upwards position under the sheet containing the multiplication table of 9, as shown in Fig. 2 in the accompanying drawings. The purpose of this method of operating the invention is to expose to the vision of the student only the multiplication table to be learnt at a given time for better concentration. In this manner, one by one, all the multiplication tables can be learnt more conveniently and more easily.

The books in the prior art are generally printed with several different multiplication tables on one page. Printing of more than one multiplication table on the same page can affect the concentration of the student to learn one particular multiplication table from that page at a given time. For example, a student is given the home work assignment to write 3 times a particular multiplication table to be learnt from the multiplication tables book in the prior art. In this case there is a possibility of the student absent-mindedly writing down one or more multiplications of another multiplication table printed adjacent to the multiplication table to be learnt by the student.The student simply cannot commit such mistakes with the invention described above. Secondiy, the reading of a multiplication table from a page of a book of the prior art can be disturbed by other pages with a flip of air and accidental or absent-minded removal of the grip on such pages. Multiplication tables device made as per the present invention is totally free from this fault. In this invention the other pages do not remain on the other side like the pages of a book of the prior art. In this invention the use of the sheets of rigid or semi-rigid material and the special binding does not allow the sheets to move on their own from one place to another place. Reading of a multiplication table from the present invention is therefore free from interruption from other pages.Thirdly, the books in the prior art are generally printed on ordinary paper and the life of such books is usually short. The multiplication-tables device made as per the present invention is made from rigid or semirigid sheets and its useful life is much more than a multiplication tables book of the prior art. The teaching of different multiplication tables is spread over different standard levels at the primary stage of the school and therefore the student can use the same multiplication tables device made as per the present invention for a longer period. It can now be noted that the present invention has a better utility value than that of a multiplication tables book of the prior art.

The present invention has many advantages over the prior art patented multiplication tables game also. Firstly, the present invention can be worked independently by a child unlike the requirement of two children for learning through the patented game. Please see complete specification No. 140531 dated 24th September 1974 of the patented Indian inven tion of "A Device; For Teaching Multiplication Tables". Secondly, the present invention enables the student to concentrate on one multiplication table to be learnt at a given time. In the prior art patented multiplication tables game multiplications of different multiplication tables have to be learnt at a time in a haphazard manner Thirdly, in the present invention learning of multiplications of a multiplication table is not left to chance.In the case of the patented game learning is left to the chances of the throws of the pairs of dice. Ordinarily a pair of dice would not throw at one game all the combinations of multiplications of a multiplication table to be learnt. This snag of the game is very well indicated in the first four lines of the last para in the first column on page 4 of the above referred complete specification. The said four lines state: "N.B. It is necessary to keep in mind that at the end of each game at every step as well as at the end of each stage, it will be profitable to repeat the tables in the proper order in the time honoured style." Fourthly, the same one unit of the present invention is useful at all age groups.Therefore, the present invention is more economical than the patented game which requires the purchase of three different sets of the game for three different age groups. Fifthly, the loss or misplacement of one or more loose parts of the patented game can make it unworkable.

Thankfully, there is no such possibility with the present invention as it is assembled in the form of a single compact unit which is very handy and convenient to work with.

-The above referred invention of An Improved Device For Teaching Multiplication Tables also enables to put into practice the principles of the psychology of teaching, learning and memorising such as interest, observation, impression, concentration and repetition, for more convenient, more effective and easier teaching, learning and memorising of multiplication tables. The special binding and the rotational. movement of. the sheets are meant to excite the interest of the student. Printing of only one multiplication table on one page of this invention gives more room for bigger print size which is easy on the eyes of the student and therefore the student can have a better observation of the numerals of the various multiplications of a multiplication table. This in turn can create a better impression of the multiplication table on the mind of the student.

The absence, on the same page, of multiplication tables other than the one multiplication table to be taught, learnt and memorised, leads to better concentration. The improved multiplication tables device as per the present invention is handy and convenient. Therefore, at any time and at any place, a student can repeatedly read and write from it a multiplication table to be learnt. The importance of teaching, learning and memorising multiplication tables is acknowledged universally. The present invention of An Improved Device For Teaching Multiplication Tables makes improvements and contribution in such important field of education.
