The utility model is formed by four cards with each of the numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, four cards with each of the mathematic symbols +,-, *, /, =, and 2 king cards; in total 54 cards. The utility model has three elementary playing methods, which can combine tightly with the teaching content of the primary school, can combine the teaching with entertainment together. The utility model can be used for the competition of 2-4 players.

Description

Numeric intelligence playing cards

The utility model belongs to a kind of student of being suitable for and uses the mathematics intelligence board that has teaching and amusement dual-use function concurrently.

Existing mah-jong pieces, playing card, word board are the recreation product of simple function, do not combine closely with the primary school teaching content of courses.

The purpose of this utility model provides a kind of teaching intelligence board with teaching and amusement double action, and residence is imparted knowledge to students among amusement, developing intelligence, the training of personnel.

In order to achieve the above object, the board of the utility model design is 54.Be symbol with numeral 0,1,2,3,4,5,6,7,8,9 promptly, each numeral has 4 same boards, adds up to 40 on digital board, with mathematic sign, ± (unlike signs) ,=(equal sign),

(taking advantage of the division sign) is symbol, and every kind has 4 same boards, adds up to 12, also has 2 of trumps.Mathematic sign ± number,

Number, be because add, inverse operation each other between the subtraction, so will add, a minus sign unification symbol, design is in one card, in like manner, the inverse operation each other of multiplication and division method is combined into a symbol with two kinds of symbols of multiplication and division, design is in one card.During use, two kinds of symbols are made by oneself a kind of.The utility model is provided with trump, and trump can be used as any numeral or symbol card uses.The utility model has designed large and small two kinds of board types, and large-scale board can be printed with thick paper or plastic film, and small-sized board can manufacture mahjong shape board type with materials such as bamboo wood, plastics, pottery, metal, aggregates.Fig. 1 is small-sized board stereogram, and Fig. 2 is large-scale board plane.

Below in conjunction with accompanying drawing the utility model is narrated, referring to Fig. 1, its small-sized board is a cuboid, is of a size of 21 * 15 * 10 millimeters; Font is a character cut in bas-relief on the board, and word is 2 millimeters deeply, and font is placed in the middle, empty 3 millimeters of limit, and font can be black matrix fine arts numeral and symbol; Though the matrix material color of board, but require the board color uniformity of every pair, Shuo Zi ?look, its color will be complementary with the basic material true qualities of board, meets requirement attractive in appearance, conspicuous.Numeral 6 and 9, font is identical, distinguishes to some extent for making two numerals, and 9 usefulness are expected the ?look with being coated with of other digital different colours.

Referring to Fig. 2, the size of its large-scale board is identical with common playing card.Every board is divided into two parts up and down, and top is numeral or symbol, and the bottom is registration, signal pattern, and numeral is a black matrix large size word, and the middle position is printed on small size numeral or symbol in the upper left corner, is printed on inverted small size numeral or symbol in the lower right corner.

The utility model makes usage, and promptly the play of board is an individuality with individual digit and symbol, and digital board can be formed arbitrary long number.According to 14 location contents of primary school math teaching, developed three kinds of basic plays, the location contents difference has concrete regulation again on play.Here the computing unit content that adds (subtracting) one digit number with the first grade of primary school double figures is an example, introduces three kinds of basic plays.

Play one: whom this law form earlier a kind of in the following formula be victory, and represents 1 digital board in the formula, represents one digit number, and represents double figures.

1. ±=uses as 15 ± 8=7(symbol ± do minus sign)

2. ±=does to add or do to subtract as 25 ± 9=34 or 16()

3. ±=does to add as 99 ± 5=104()

Everyone gets 5 on board in turn, the first get 1 (6) more, want to take formula 1. to accord with board as the first, just get 1 to the disadvantageous board of group formula, as want to take formula 2. to accord with board, can state and not get, on the board pier, grab 1 board by second people, also can be by oneself determining the formula of being taked and getting board.As taking 3. formula symbol board, can twice statement not get board, to increase the board number in the hand, but in the hand unnecessary board can not be arranged during the symbol board, the board others that people gets can eat board (trump card is received in the own hand and gone) in turn, except that exempting to beat for the board number statement that increases oneself, all the other eat 1 will get 1.So constantly disadvantageous board in the hand is changed one by one, 1 appropriate board the most afterwards, equation is formed, and just cries to accord with board, is put on the table claim victory.This law is suitable for 2-4 people and participates in.

Play two: at first the symbol in the trump card goes out clearly, and " ± ", "=" are each one on the table, and all the other need not.3-4 people participates in, and " washing " bridge queen opens 1, determines at first to play a card the people.Trump card has been got in turn.From the first, everyone takes turns and flows out 1 board and put well by the equation order, does to add to do to subtract by equal sign the right to go out the first of total or second people makes by oneself.After forming an equation, numeral is found on one side, recombinate second equation and continuation when whom taking turns to when not having appropriate board and can go out (mainly be fractional part), be borrowed 2 on board (but having no right to specify which type of board), and stop once from the staff on the left side.If when everybody lacked certain board, equation was also finished.Board in whose hand has gone out earlier for winning.

Play three: 4 people participate in, and symbol is gone out clearly, only stays each 1 of " ± ", "=" on the table, after shuffling, therefrom opens 1, determines first person of playing a card.Trump card has been got in turn, the firstly plays a card 2, and all the other 3 people respectively go out 1 board, by the first equation of forming, if can form, and 5 boards in the equation are recovered in the own hand, lay equal stress on and play a card.As not forming equation, each one regains the board of oneself, takes the lead to play a card 2 by second people, and play is the same.Gone out if any the board in the staff, the overall situation finishes, and is victory with the maximum persons of board in the hand.This play cans be compared to fishing, and the difficulty of winning victory can cultivate patience.

These play are easy to learn.In the process of playing cards, carry out computing many times and just can win victory, to tap intellectual resources, the training numeracy skills is very helpful.With play one 2. formula be example, 5 digital boards are by numeral, can be arranged in 120 kinds of forms, add that two kinds of algorithms of different (addition, subtraction) can form 240 formulas, in 240 formulas, may not have the same form and set up, having the same form or a few formula sets up, this just illustrates that the probability of winning victory is little, in order to win victory, requires oneself to improve constantly arithmetic speed.Therefore, the utility model is a kind of and the compact strong intellection recreation product of study.

Claims (1)

1. A kind of student of being suitable for uses the mathematics intelligence board that has teaching and amusement dual-use function concurrently, and the every secondary board of its feature is by respectively 4 of 0,1,2,3,4,5,6,7,8,9 numerals, ± (unlike signs), ^* _÷(taking advantage of the division sign) ,=2 of (number of equaling) mathematic sign each 4 and trumps amount to 54 boards and form.
