Abstract
Description
[Technical Field]
[0001] This invention relates to a teaching tool for learning numbers. [Background technology]
[0002] Generally, mathematics is the study of numbers and quantities, which begins with counting or measuring things. This kind of mathematics is the foundation for most other disciplines.
[0003] Preschoolers learn to distinguish between single-digit numbers from 0 (zero) to 9 (nine), then move on to double-digit numbers from 10 (ten) to 99 (ninety-nine). They then expand on this and learn how to read numbers with units such as hundreds, thousands, and millions.
[0004] However, for children learning mathematics for the first time, when there are many numbers lined up, it is difficult to distinguish between units, and they often end up simply reading the numbers in a row without using units.
[0005] Although various tools have been developed and used to solve the difficulties of learning numbers, the reality is that there are still no tools that are clearly effective in learning how to read numbers using units.
[0006] In this case, there is a possibility that an opportunistic educational policy will be pushed to use rote-based education, ignoring the position of children who are encountering mathematics for the first time. This will have a highly adverse educational effect, as children who learn using a simple rote-based approach will either see their grades decline as they get older, or will be unable to solve even slightly difficult problems because they lack the problem-solving skills to do so. Summary of the Invention [Problem to be solved by the invention]
[0007] The present invention was devised to solve the problems of the prior art as described above. The object of the present invention is to provide a teaching tool for learning numbers that enables children to read numbers by using units without losing interest and to easily acquire the magnitude of numbers.
Means for Solving the Problems
[0008] The teaching tool for learning numbers according to one aspect of the present invention includes unit cards on which numbers and the corresponding readings are written. The unit cards include a plurality of single - unit cards with numbers from 1 (one / ichi) to 9 (nine / kyuu / ku) written at the top and the readings written at the bottom, a plurality of ten - unit cards with a number whose first digit is from 1 (one / ichi) to 9 (nine / kyuu / ku) and the remaining digits all being 0 (zero / rei) written at the top and the reading written below the first digit, a plurality of hundred - unit cards with a number whose first digit is from 1 (one / ichi) to 9 (nine / kyuu / ku) and the remaining digits all being 0 (zero / rei) written at the top and the reading written below the first digit, a plurality of thousand - unit cards with a number whose first digit is from 1 (one / ichi) to 9 (nine / kyuu / ku) and the remaining digits all being 0 (zero / rei) written at the top and the reading written below the first digit, and a plurality of ten - thousand - unit cards with a number whose first digit is from 1 (one / ichi) to 9 (nine / kyuu / ku) and the remaining digits all being 0 (zero / rei) written at the top and the reading written below the first digit. When at least two or more of the single - unit cards, the ten - unit cards, the hundred - unit cards, the thousand - unit cards, and the ten - thousand - unit cards are arranged in units, they are arranged such that the readings of each unit card are shifted from each other, so that they are combined to form the reading corresponding to the number combined by each unit card.
[0009] Specifically, the ten - unit cards, the hundred - unit cards, the thousand - unit cards, and the ten - thousand - unit cards include an upper part on which a number is written and a lower part that extends downward from the first digit of the number and on which the reading is written, and can have an inverted L - shaped form.
[0010] Specifically, when at least two of the one unit cards, the tens unit cards, the hundreds unit cards, the thousands unit cards, and the 10,000 unit cards are stacked according to the units, the readings of the unit cards are shifted from each other and arranged left and right, so that they can be combined to form a reading that corresponds to the number combined by the unit cards; and when at least two of the one unit cards, the tens unit cards, the hundreds unit cards, the thousands unit cards, and the 10,000 unit cards are placed face to face according to the units, the readings of the unit cards are shifted from each other and arranged diagonally, so that they can be combined to form a reading that corresponds to the number combined by the unit cards.
[0011] Specifically, the numbers of the units card, the tens card, the hundreds card, the thousands card, and the tens of thousands card may be displayed in different colors, and the readings may be displayed in the same color. [Effects of the Invention]
[0012] The teaching tool for learning numbers according to this invention is composed of a plurality of cards on which numbers and letters corresponding to numbers in different units are written, and by arranging the cards one on top of the other or adjacent to each other, the letters can be arranged side by side, thereby enabling students to learn how to easily read even large numbers by reading the letters in order, thereby making it easy to learn large numbers.

[0014] The objects, particular advantages, and novel features of the present invention will become more apparent from the following detailed description and preferred embodiments taken in conjunction with the accompanying drawings. In this specification, when referring to components in each drawing, please note that the same components are referred to by the same reference numerals whenever possible, even if they appear in different drawings. In describing the present invention, if it is determined that a detailed description of related prior art may unnecessarily obscure the gist of the present invention, such a detailed description will be omitted.
[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0016] Figure 1 shows one-unit cards for a number learning tool according to one embodiment of the present invention, Figure 2 shows tens-unit cards for a number learning tool according to one embodiment of the present invention, and Figure 3 shows hundreds-unit cards for a number learning tool according to one embodiment of the present invention. Also, Figure 4 shows thousands-unit cards for a number learning tool according to one embodiment of the present invention, and Figure 5 shows 10,000-unit cards for a number learning tool according to one embodiment of the present invention. Furthermore, Figures 6 and 7 show how to use a number learning tool according to one embodiment of the present invention.
[0017] 1 to 7, a teaching tool 1 for learning numbers according to one embodiment of the present invention includes unit cards 10, 20, 30, 40, and 50. The unit cards 10, 20, 30, 40, and 50 are made of any material, such as paper, plastic, or metal, are easily portable, and can be stacked on top of each other.
[0018] Numbers and letters are written on the unit cards 10, 20, 30, 40, and 50. Numbers will be described later, but numbers of different units can be written on the unit cards 10, 20, 30, 40, and 50 depending on their types.
[0019] The characters written on the unit cards 10, 20, 30, 40, and 50 may be phonetic symbols for the pronunciation of the numbers written on the unit cards 10, 20, 30, 40, and 50. In this case, the characters refer to characters other than numbers, and may be Hangul, Chinese characters, etc. Furthermore, the characters may be in English, and the language of any country that counts numbers by dividing units may be used.
[0020] The numbers on the unit cards 10, 20, 30, 40, and 50 can be written at the top and the letters at the bottom. In this case, when the unit cards 10, 20, 30, 40, and 50 are stacked or butted horizontally, the numbers and letters can be combined. In particular, the present invention can form letter combinations corresponding to number combinations so that the combined readings are the readings of the numbers they combine.
[0021] Of course, the arrangement of the numbers and letters may be reversed on the unit cards 10, 20, 30, 40, and 50. However, the present invention allows the direction in which the unit cards 10, 20, 30, 40, and 50 are stacked or placed adjacent to each other to be at a 90-degree angle to the direction in which the numbers and letters are arranged.
[0022] The unit cards 10, 20, 30, 40, 50 can include a single - unit card 10, a ten - unit card 20, a hundred - unit card 30, a thousand - unit card 40, a ten - thousand - unit card 50, etc., and the types of the unit cards 10, 20, 30, 40, 50 can be determined according to the types of units.
[0023] Specifically, as shown in FIG. 1, the single - unit card 10 has numbers 1 (one, ichi) to 9 (nine, kyuu / ku) written on the upper part and the reading methods written on the lower part, and can be composed of a total of 9 cards. When stacking the unit cards 10, 20, 30, 40, 50, the single - unit card 10 is stacked at the topmost layer, and the widths of the places where the numbers are arranged and the places where the reading methods are arranged may be the same.
[0024] As shown in FIG. 2, the ten - unit card 20 has a ten - unit number with the first digit being 1 (one, ichi) to 9 (nine, kyuu / ku) and the remaining digits all being (zero, rei) written on the upper part, and the reading method is written below the first digit. That is, as numbers, the ten - unit card 20 has 10 (ten, juu), 20 (twenty, nijuu), 30 (thirty, sanjuu), 40 (forty, yonjuu / shijuu), 50 (fifty, gojuu), 60 (sixty, rokujuu), 70 (seventy, nanajuu), 80 (eighty, hachijuu), or 90 (ninety, kyuuju) written, and the reading methods corresponding to each number are written, and it is composed of a total of 9 cards. <***
[0025] As shown in FIG. 3, the hundred - unit card 30 has a hundred - unit number with the first digit being 1 (one, ichi) to 9 (nine, kyuu / ku) and the remaining digits all being 0 (zero, rei) written on the upper part, and the reading method is written below the first digit. That is, as numbers, the hundred - unit card 30 has 100 (hundred, hyaku), 200 (two hundred, nihyaku), 300 (three hundred, sanbyaku), 400 (four hundred, yonhyaku), 500 (five hundred, gohyaku), 600 (six hundred, roppyaku), 700 (seven hundred, nanahyaku), 800 (eight hundred, happhyaku), or 900 (nine hundred, kyuuhyaku) written, and the reading methods corresponding to each number are written, and it is composed of a total of 9 cards.
[0026] As shown in Figure 4, thousands-unit cards 40 have thousands-unit numbers written at the top, with the first digit being 1 (one) to 9 (nine), and the remaining digits all being 0 (zero), and the readings are written below the first digit. That is, thousands-unit cards 40 have the numbers 1000 (thousand), 2000 (two thousand), 3000 (three thousand), 4000 (four thousand), 5000 (five thousand), 6000 (six thousand), 7000 (seven thousand), 8000 (eight thousand), or 9000 (nine thousand), and the readings corresponding to each number are written on them, and there are nine of them in total.
[0027] As shown in Figure 5, the 10,000-unit cards 50 have a number in the 10,000-unit range written at the top, with the first digit ranging from 1 (ichi) to 9 (kyuu / ku) and the remaining digits all being 0 (rei), and the reading is written below the first digit. That is, the 10,000-unit cards 50 have the numbers 10,000 (man, man), 20,000 (niman, niman), 30,000 (sanman, sanman), 40,000 (yonman, yonman), 50,000 (goman, goman), 60,000 (rokuman, rokuman), 70,000 (nanama, sevenman), 80,000 (hachiman, hachiman), or 90,000 (kyuman, kyuman), and the reading corresponding to each number is written on them, for a total of nine cards.
[0028] In the case of the 10 unit cards, the reading is written below the first digit of the number, so the number and reading can be arranged vertically side by side. In contrast, the 20 tens unit cards, 30 hundreds unit cards, 40 thousands unit cards, and 50 tens of thousands unit cards have the reading written only below the first digit of the number.
[0029] That is, the tens cards 20, hundreds cards 30, thousands cards 40, and 10,000 cards 50 comprise an upper portion on which numbers are written and a lower portion extending downward from the first digit of the number on which the reading is written, and may be configured to have, for example, an inverted L shape.
[0030] In this case, the unit cards 10, 20, 30, 40, and 50 can be colored for children's education. That is, the numbers on the units card 10, the tens card 20, the hundreds card 30, the thousands card 40, and the tens of thousands card 50 can be displayed in different colors.
[0031] However, the readings for the unit cards may be displayed in the same color as each other, which indicates the unit meaning in the number, and allows the readings to be read consecutively all at once.
[0032] The method of using the present invention will now be described with reference to FIGS.
[0033] First, referring to FIG. 6, the child user can stack at least two or more of the units of one card 10, ten card 20, hundred card 30, thousand card 40, and ten thousand card 50 according to the unit.
[0034] As an example, the card with the next highest denomination is placed on top of the highest denomination card, for example, stacking unit cards 10, 20, 30, 40, 50 in order with the ones card 10 on top. In this case, the 0 (zero·rei) in the ones digit of the tens card 20 is hidden by the ones card 10, and the 00 (zero·rei·rei) in the ones / tens digit of the hundreds card 30 is hidden by the tens card 20. Also, the 000 (zero·rei·rei·rei) in the ones / tens / hundreds digit of the thousands card 40 is hidden by the hundreds card 30, and the 0000 (zero·rei·rei·rei·rei) in the ones / tens / hundreds digit of the tens card 50 is hidden by the thousands card 40.
[0035] When the unit cards 10, 20, 30, 40, and 50 are stacked in this way, numbers can be combined using the unit cards 10, 20, 30, 40, and 50. At the same time, the readings of the unit cards 10, 20, 30, 40, and 50 can also be combined. In particular, in this device, the unit cards 20, 30, 40, and 50 of all types except for one unit card 10 have an inverted L-shape, so that even when the unit cards 10, 20, 30, 40, and 50 are stacked, the readings of the unit cards 10, 20, 30, 40, and 50 can be arranged side by side with a shift between them. In this case, the lined-up readings are combined to form readings that correspond to the numbers combined using the unit cards 10, 20, 30, 40, and 50.
[0036] Therefore, if a user can read the pronunciation of the combinations of unit cards 10, 20, 30, 40, and 50, they can read the numbers combined with unit cards 10, 20, 30, 40, and 50. This allows the user to effectively learn the combinations of numbers with different units and the accompanying pronunciation methods.
[0037] 7, the user may place the unit cards 10, 20, 30, 40, and 50 side by side without overlapping. That is, the unit cards 10, 20, 30, 40, and 50 can be matched by interlocking the unit card of the highest unit with the unit card of the next highest unit. In this case, the numbers on the unit cards 10, 20, 30, 40, and 50 do not overlap, and the letters are offset from each other.
[0038] When arranging the unit cards as shown in Figure 7, the readings of the unit cards 10, 20, 30, 40, and 50 are arranged diagonally, offset from each other. When the readings are read consecutively, they correspond to the numbers combined by the unit cards.
[0039] In this case, the numbers on the unit cards 10, 20, 30, 40, and 50 do not overlap each other, and the first digits of the unit cards 10, 20, 30, 40, and 50 can be arranged diagonally and combined. Furthermore, the arrangement shown in Figure 7, in which the unit cards 10, 20, 30, 40, and 50 are arranged one above the other, can explain not only how to read the units of numbers, but also the concept of adding numbers of different units.
[0040] Of course, the present invention may not use all of the different unit cards 10, 20, 30, 40, and 50, as shown in Figures 6 and 7. For example, only the 10,000 unit card 50 and the 100 unit card 30 may be combined as shown in Figure 6 or 7, and in this case, the user can still read the numbers combined by the unit cards 10, 20, 30, 40, and 50 through the combined reading method.
[0041] In this way, this invention allows children who have difficulty reading numbers in larger units to play by combining unit cards (10, 20, 30, 40, 50) that have readings written on them according to the unit, allowing them to approach larger numbers without hesitation and stimulating their interest in mathematics.
[0042] Although the present invention has been described in detail above using specific embodiments, these are merely for the purpose of specifically explaining the present invention, and the present invention is not limited thereto. It is clear that modifications and improvements can be made by those skilled in the art within the scope of the technical idea of the present invention.
[0043] Any simple modifications or variations of the present invention should fall within the scope of the present invention, and the specific scope of protection of the present invention should be defined by the appended claims. [Explanation of symbols]
