Description

  The present invention relates to an arithmetic table and an arithmetic method for performing calculation practice in arithmetic education at an elementary school, for example.

  Arithmetic education is performed in elementary schools, and in this arithmetic education, for example, four arithmetic operations are learned. Arithmetic operations are addition, subtraction, multiplication, and division, and these four arithmetic operations are the most basic and important learning items in arithmetic education. In order to acquire the calculation ability of such four arithmetic operations, it is necessary to repeatedly perform calculation practice. For this reason, various calculation problem collections have been used conventionally.

  In a general collection of calculation questions, for example, a plurality of calculation formulas such as “2 × 3 =” and “15 ÷ 3 =” are printed on a sheet, and an answer numerical value obtained as a result of calculation for each calculation formula is obtained. Each is written in an answer column provided next to each calculation formula. However, due to the size of the paper, there are cases where the number of calculation formulas to be printed on one sheet cannot be increased so much. In such a case, a predetermined number of calculation formulas are provided over a plurality of sheets of paper. Had to be printed, and wasted paper.

  Therefore, in recent years, an arithmetic table that can perform many operations in one table has been proposed (see, for example, Patent Document 1), and this arithmetic table has the configuration shown in FIG. Referring to FIG. 7, the illustrated arithmetic table 100 includes an answer value column 104 in which a plurality of cells 102 are arranged in a checkerboard pattern, and a first number arranged corresponding to two orthogonal sides of the answer value column 104. The arithmetic table 100 is printed on a sheet 112. The arithmetic table 100 includes a first problem numerical value column 106 and a second problem numerical value column 108. In each of the first and second problem numerical value columns 106 and 108, a plurality of cells in which problem numerical values are entered are arranged in a line. An example of a method for performing the calculation is as follows. For example, the column 104a of the answer value column 104 corresponding to the question value “5” (number in the fifth column) displayed in the first question value column 106, and the second question value Displayed in the upper left part of the arithmetic table 100 in the cell 102a of the answer value column 104 where the row 104b of the answer value column 104 corresponding to the question value “7” (number in the sixth row) displayed in the column 108 intersects. An answer obtained as a result of performing the addition operation “5 + 7” with the problem value “5” in the first problem value field 106 and the problem value “7” in the second problem value field 108 in accordance with the operation symbol 110 “+”. Enter the value “12”.

Utility Model Registration No. 3094881

  However, the conventional arithmetic table 100 as described above has the following problems. When performing calculations using this arithmetic table 100, for example, answer numbers are entered in order from the leftmost cell 102 to the rightmost cell 102 in the first (ie, top) answer value column 104. Next, the answer numerical values are entered in order from the leftmost cell 102 to the rightmost cell 102 in the answer value column 104 in the second row. At this time, when the answer numerical value column 104 is composed of a very large number (for example, 10 or more) of cells 102, the cell 102 of the answer numerical value column 104 to which the answer numerical value is to be entered is displayed in the answer numerical value column 104. The closer to the bottom level (that is, the farther away from the first question value column 106 and the second question value column 108), the question value in the first question value column 106 and the question value in the second question value column 108 corresponding to this cell 102. Becomes difficult to see. For this reason, the problem numerical values in the first and second problem numerical value columns 106 and 108 may be mistaken, resulting in a problem that accurate calculation cannot be performed. Also, if you try to check the correct question numerical value by tracing the column or row of the answer numerical value column 104 with a pencil etc., it takes a lot of time to answer all the questions, and the calculation efficiency decreases, There was a problem that the original calculation ability could not be known.

  Referring to FIG. 1, the illustrated arithmetic table 2 includes a plurality of calculation columns 4 arranged in a predetermined direction (vertical direction in the present embodiment) (ten in the present embodiment). The calculation column 4 is formed in a horizontally long rectangular shape, and the inside thereof is divided into two regions on the left and right by a solid first partition line 6 extending in the vertical direction. Each region is divided into a first region 8 and a first region. Two areas 10 are formed. The first region 8 is a region on the right side of the first partition line 6 in FIG. 1, and the second region 10 is a region on the left side of the first partition line 6 in FIG. The outer frame of the calculation column 4 is formed with a double line.

  In the first area 8 of the calculation column 4, a first question numerical value column 12 and an answer numerical value column 14 arranged corresponding to the first question numerical value column 12 are provided. Specifically, the first area 8 is divided into two upper and lower areas by a dotted second partition line 16 extending in the horizontal direction, and a first problem numerical value column 12 is arranged in this upper area, and An answer numerical value column 14 is arranged in the lower area. In the second area 10 of the calculation column 4, a calculation symbol column 18 and a second question value column 20 arranged corresponding to the answer value column 14 are provided. Specifically, the second area 10 is divided into two upper and lower areas by the second partition line 16, the second problem numerical value column 20 is arranged in the lower area, and the upper area is An operation symbol column 18 is arranged.

  In the first problem numerical value column 12, a plurality (10 in this embodiment) of cells 24 in which problem numerical values 22 are entered are arranged in a line in the horizontal direction. In this embodiment, a problem numerical value 22 consisting of a one-digit integer from 0 to 9 is entered in each cell 24 of the first problem numerical value column 12. In addition, among the four sides of the cell 24 in the first problem numerical value column 12, the side adjacent to the cell 24 is formed by a dotted line.

  The answer numerical value column 14 includes a plurality of (10 in the present embodiment) cells corresponding to each of the question values 22 of the first question value column 12 (that is, each of the plurality of cells 24 of the first question value column 12). 26 are arranged in a line in the horizontal direction. Therefore, each of the plurality of cells 26 in the answer numerical value column 14 is adjacent to each of the plurality of cells 24 in the first question numerical value column 12 in the vertical direction. Moreover, among the four sides of the cell 26 in the answer value column 14, the sides adjacent to the cell 26 are formed by dotted lines. Before use of the arithmetic table 2, nothing is entered in each cell 26 of the answer value column 14, and when the operation is performed as will be described later, an answer value obtained as a result of the operation is stored in each cell 26. Fill in each by hand.

  The second problem numerical value column 20 is composed of one cell 32 in which a problem numerical value 30 is entered. The second question numerical value column 20 is provided adjacent to the left end portion of the answer numerical value column 14. In this embodiment, a problem numerical value 30 consisting of a one-digit integer from 0 to 9 is entered in each cell 32 of each second problem numerical value column 20.

  The operation symbol column 18 is composed of one cell 36 in which an operation symbol 34 is entered. In the present embodiment, a calculation symbol 34 of “+” indicating addition is entered in the cell 36 of the calculation symbol column 18, and calculation is performed in accordance with the calculation symbol 34 in each calculation column 4 as will be described later. The operation symbol column 18 is provided adjacent to the left end portion of the first question numerical value column 14 and adjacent to the upper end portion of the second question numerical value column 20.

  Arithmetic table 2 is formed by arranging ten calculation columns 4 configured as described above in the vertical direction adjacent to each other. In the arithmetic table 2 according to the present embodiment, the number of cells 26 in the answer value column 14 is 100 (10 × 10 =) in total, so that one arithmetic table 2 can perform 100 calculations. The arithmetic table 2 is printed on a sheet 38, and an entry column 40 for entering a date, a name, and the like is printed below the arithmetic table 2. For example, when performing a test or the like for accrediting calculation ability using this arithmetic table 2, the answerer writes the date, name, etc. in this entry column 40 by hand. Further, such an entry column 40 can be omitted.

  In this embodiment, in order to make the arithmetic table 2 easy to see, the outer frame of the calculation column 4 is formed by a double line, the first partition line 6 is formed by a solid line, and the second partition line 16 and the second partition line 16 A part of the squares 24 in the 1 question numerical value column 12 and the squares 26 in the answer numerical value column 14 are each formed by a dotted line, but these are formed by arbitrary line types (for example, a solid line, a dotted line or a one-dot chain line). Is also possible. In the present embodiment, the calculation columns 4 are arranged adjacent to each other, but are arranged with a predetermined interval (that is, with a predetermined gap between the calculation column 4 and the calculation column 4). Is also possible.

  Next, with reference to FIG. 2, a method for performing an operation using the arithmetic table 2 according to the present embodiment will be described. For example, when the calculation is performed in the leftmost cell 26a of the answer value column 14a arranged in the calculation column 4a in the first level (that is, the uppermost level), the first corresponding to the cell 26a of the answer value column 14a is first performed. The problem numerical value 22a in the first problem numerical value column 12a and the problem numerical value 30a in the second problem numerical value column 20a are read. The question numerical value 22a of the first question numerical value column 12a corresponding to the cell 26a of the answer numerical value column 14a is the question numerical value "written in the cell 24a of the first question numerical value 12a adjacent to the upper side of the cell 26a of the answer numerical value column 14a". 4 ". Also, the question value 30a in the second question value column 20a corresponding to the cell 26a in the answer value column 14a is the question value “in the cell 32a of the second question value column 20a adjacent to the left side of the answer value column 14a. 8 ". Since the “+” calculation symbol 34a indicating addition is entered in the calculation symbol column 18a of the first calculation column 4a, addition calculation is performed in the first calculation column 4a. Therefore, in the cell 26a of the answer value column 14a, an operation "4 + 8" is performed for adding the question value "4" in the first question value column 12a and the question value "8" in the second question value column 20a. Then, the answer numerical value “12” obtained as a result of this calculation is handwritten in the cell 26a of the answer numerical value column 14a.

  In the same manner, addition is performed in the other cells 26 in the first answer value column 14 and the answer values 28 are entered in each cell 26, and also in the answer value columns 14 in the second and subsequent steps. An addition operation is performed, and an answer value 28 is entered in each cell 26.

  The arithmetic table 2 according to the present embodiment has the following characteristics. First, since the first question numerical value column 12 is provided corresponding to each answer numerical value column 14, there are a large number of cells 26 constituting the answer numerical value column 14 as in the present embodiment. The problem numerical value 22 in the first question numerical value column 12 and the problem numerical value 30 in the second question numerical value column 20 corresponding to the cell 26 in the answer numerical value value 14 in which the answer numerical value 28 is to be entered can be solved. Therefore, it is possible not to mistake the problem numerical values 22 and 30 in the first and second problem numerical value columns 12 and 20 when performing the calculation, so that it is possible to perform an accurate calculation and increase the calculation efficiency. Become.

  Secondly, in the conventional collection of calculation problems that are simply enumerated, there is no fun even if you are practicing calculation, so you can effectively practice calculation without concentrating or losing motivation. However, in the arithmetic table 2 according to the present embodiment, the calculation practice can be performed while having fun as if solving the puzzle, so that the calculation ability can be effectively improved. Therefore, it is effective to actively use this arithmetic table 2 when, for example, elementary school students practice mental arithmetic, or when elderly people practice calculation to prevent dementia.

  Third, for example, in each first question value column 12, problem values 22 consisting of integers from 0 to 9 are entered in order from the leftmost cell 24, and the first step is entered in each second question value column 20. By entering the problem numerical value 30 consisting of integers from 0 to 9 in order from the smallest, it is possible to perform all the multiplications in one arithmetic table 2. Therefore, for example, in elementary school arithmetic education, it is possible for elementary school students to effectively memorize the tables while having fun.

  In this embodiment, ten calculation columns 4 are arranged, and the first question numerical value column 12 and the answer numerical value column 14 are each configured with ten cells 24 and 26. However, the present invention is not limited to this, and the calculation column 4 The number of squares 24 in the first question numerical value column 12 and the number of squares 26 in the answer numerical value column 14 can be appropriately set to arbitrary numbers. Further, in the present embodiment, the problem values 22 and 30 made up of single-digit integers are entered in the cells 24 and 32 of the first problem value field 12 and the second problem value field 20, but the present invention is not limited to this. Various numbers such as integers of two digits or more, fractions, or decimals can be set as problem numerical values.

  Furthermore, in the present embodiment, the case of performing the addition operation has been described. However, the present invention is not limited to this, and subtraction, multiplication, or division may be performed. In this case, “−”, “×”, or “÷”, respectively. The operation symbol 34 of “” may be entered in the operation symbol column 18. Alternatively, a calculation in which four rules are mixed in one arithmetic table 2 may be performed. For example, four calculation symbols 34 may be randomly entered in the calculation symbol column 18 of each calculation column 4. Further, in the second region 10 of the calculation column 4, the second problem numerical value column 20 is arranged in the region above the second partition line 16, and the calculation symbol column 18 is disposed in the region below the second partition line 16. May be arranged.

Second Embodiment Next, an arithmetic table according to a second embodiment will be described with reference to FIG. FIG. 3 is a plan view showing an arithmetic table according to the second embodiment. In the following embodiments, the same reference numerals are given to substantially the same components as those of the first embodiment, and the description thereof is omitted.

  Referring to FIG. 3, in the arithmetic table 2A of the second embodiment, eight calculation columns 4 are arranged in the vertical direction, and the cell 36 of each calculation symbol column 18 indicates “÷” indicating division. Calculation symbols 34 are entered. Each cell 26A in the answer value column 14A is filled with a diagonal line 42, and each cell 26A is divided into two left and right regions 44a and 44b by the diagonal line 42, respectively. As a result, when division is performed as an operation, the quotient is written in one area 44a (left side of the diagonal line) of each cell 26A, and the remainder is written in the other area 44b (right side of the diagonal line). The

  A calculation method using the arithmetic table 2A according to the second embodiment will be described. For example, in the case where the calculation is performed in the leftmost box 26A of the answer numerical value column 14A in the first row, the question numerical value 22 of the first question numerical value column 12 corresponding to the cell 26A of the answer numerical value column 14A is “2”. In addition, the problem numerical value 30 in the second problem numerical value column 20 is “2”. Accordingly, the division operation “2 ÷ 2” is performed using the question value “2” in the first question value column 12 and the question value “2” in the second question value column 20, and the answer value “ Enter "quotient 1, remainder 0" in cell 26A of answer value column 14A. At this time, the quotient “1” is entered in the area 44a of the cell 26A, and the remainder “0” is entered in the area 44b of the cell 26A. Similarly, in the second square 26A from the left end of the first step answer value column 14A, the division operation “15 ÷ 2” is performed, and the answer value “quotient 7, remainder 1” obtained as a result of the operation is answered. Use the same method to enter the cell 26A in the numerical value column 14A.

  In the conventional arithmetic table, when division is performed as an operation, for example, when an answer value “quotient 2, remainder 1” is entered in the cell of the answer value column, a quotient and a remainder such as “2, 1”, etc. During this period, the writers had to write the commas by hand, which was very time consuming. In addition, there is a case where the comma is forgotten too much to rush the calculation. In such a case, there is a problem that the scorer cannot perform accurate scoring when scoring the calculation result. On the other hand, in the arithmetic table 2A according to the present embodiment, each cell 26A of the answer value column 14A is divided into two regions 44a and 44b, respectively, and the quotient and the remainder that are the answer values are shown in the regions 44a and 44b, respectively. Since it only needs to be entered, the answer value can be accurately and quickly entered in the square 26A of the answer value column 14A, and accurate scoring can be performed when the scorer scores the calculation result. .

Third Embodiment Next, an arithmetic table according to a third embodiment will be described with reference to FIG. FIG. 4 is a plan view showing an arithmetic table according to the third embodiment.

The number “1” surrounded by a circle is entered in the stage number display field 46 of the calculation field 4B arranged in the first stage.

  Thereby, for example, when a large number (for example, several tens to several hundreds) of the calculation columns 4B are arranged in the vertical direction, it is possible to see at what stage the certain calculation column 4B is arranged. You can find out at Therefore, it is possible to know how many questions the answerer is answering while performing the calculation, and it is possible to quickly count how many questions the correct answer is when the grader scores the calculation result. It becomes.

  In addition, the type of calculation to be performed in the calculation column 4B (in this embodiment, “subtraction” character) is displayed on the display unit 50 printed outside the arithmetic table 2B and in the upper left portion of the paper 38. . Thereby, it is understood that the subtraction operation may be performed in each operation column 4B of the arithmetic table 2B.

  The second problem numerical value column 20 and the calculation symbol column 18 may be provided in the second area 10 of the calculation column 4B, and the stage number display column 46 may be provided adjacent to the left end of each calculation column 4B. Alternatively, only the second problem numerical value column 20 may be provided in the second area 10 of the calculation column 4B without providing such a stage number display column 46. In this case, arithmetic is performed as in the present embodiment. A display unit 50 that displays the type of calculation to be performed outside Table 2B is provided.

  In the present embodiment, the circled number is entered in the stage number display field 46 of the calculation field 4B. However, the present invention is not limited to this. For example, alphabetic characters, other characters and symbols, etc. are entered. You may do it. For example, alphabetical characters arranged in the order of ABC such as “A”, “B”, “C”,... May be entered in order from the column number display column 46 in the first column 4B. Alternatively, kana characters arranged in the order of “I”, “B”, “C”,... May be entered. As a result, similarly to the above, it is possible to easily know at which level each calculation column 4B is arranged.

  For example, in each of the above embodiments, the problem numerical value is composed of Arabic numerals, but is not limited thereto, and may be composed of, for example, Chinese numerals, Roman numerals, or pictograms and symbols corresponding to predetermined numerals. For example, when the number “1” is represented, the problem numerical value is composed of one apple pictogram, and when the number “3” is represented, the problem numerical value is composed of three apple pictograms. This other modification will be described with reference to FIG. 6. When an operation is performed in the leftmost cell 26 of the answer value column 14 arranged in the first operation column 4 of the arithmetic table 2D, the answer value field 14 The first problem numerical value column 12 corresponding to the square 26 has a problem numerical value 22D composed of two apple pictograms, and the numerical value represented by the problem numerical value 22D is “2”. In addition, the second question numerical value column 20 corresponding to the cell 26 of the answer numerical value column 14 is filled with a question numerical value 22D composed of one apple pictogram, and the numerical value represented by the question numerical value 22D is “1”. Is. Accordingly, the calculation “2 + 1” is performed in the cell 26 of the answer value column 14, and in this case, the answer value consisting of the number “3” may be entered in the cell 26 of the answer value column 14, or You may enter an answer value consisting of three apple pictograms. In this way, by constructing problem values with pictographs such as fruits and animals, it becomes possible for toddlers and others to practice happily in a playful sense, and this arithmetic table 2D is effective as a teaching material for arithmetic education for young children. Can be used. Note that the arithmetic symbol 34 may be composed of pictographs and symbols that are easy for an infant to understand, instead of symbols such as “+” and “x”.

  Further, for example, in each of the above embodiments, the arithmetic table 2 (2A, 2B, 2C, 2D) is used by printing on the paper 38. However, the present invention is not limited to this, and the arithmetic table is displayed on the screen of the personal computer by predetermined software. It is also possible to use it. Although not shown, for example, when the arithmetic table 2 shown in FIG. 1 is displayed on the screen of the personal computer, in the initial state, the cursor is a cell 26 at the left end of the answer value column 14 arranged in the calculation column 4 in the first row. The numerical value of the answer is input to the cell 26 where the cursor is positioned using the numeric keypad of the keyboard. When the answer numerical value is input in this way, the cursor automatically moves to the right cell 26 and the next calculation can be performed. When the cursor is positioned in the rightmost cell 26 in the first-level answer value column 14, if an answer value is entered, the cursor automatically enters the left-most cell 26 in the second-level answer value column 14. Move to.

  Further, for example, predetermined data such as a problem numerical value is stored in a server on the Internet, and the predetermined data is downloaded from this server to a personal computer installed in a home or a school. You may make it perform the calculation by an arithmetic table in a personal computer. In this case, data such as the numerical value of the answer obtained by calculation and the time required to correctly answer all questions are transmitted from each personal computer to the server, and the calculation capability of each answerer is evaluated in the server based on these data. It is also possible to do so.

  Alternatively, the arithmetic table 2 may be displayed on the display of the mobile phone so that the arithmetic can be performed in the same manner. For example, the arithmetic table 2 may be displayed on the display unit of the board-type arithmetic educational game machine. Good.
