Description

Card special for calculating 24 points

Technical Field

The invention relates to the technical field of education, in particular to an auxiliary tool for developing a 'calculate 24 points' intelligence developmental game.

Background

The '24-point' game is a well-known calculation type intelligence-developing game for Chinese and overseas Chinese, and is a mathematical game which strives for a final calculation result of 24 by adding, subtracting, multiplying and dividing given 4 positive integers and carrying out bracket operation. The '24 points' is helpful for testing and exercising the intelligence and mathematical sensibility of the participator and is helpful for improving the mental calculation ability of the participator through the game.

The traditional way of "calculating 24 points" is mostly to use playing cards to play the game. In a standard deck of playing cards, a total of 54 cards are left, and 52 cards are left after the size of the cards is queen, and the '24-point' game can only use 40 cards from the number 1 to the number 10 (the card 'A' is counted as the number 1) or can be expanded to all 52 cards (the card 'J' is counted as the number 11, the card 'Q' is counted as the number 12 and the card 'K' is counted as the number 13). The player arbitrarily draws 4 cards to form a calculation card group, the card face numbers (allowing repetition) of the 4 cards in the calculation card group form a given number group of the calculation, the player needs to calculate the 4 numbers in the given number group by adding, subtracting, multiplying and dividing (using bracket calculation) to obtain 24, and each number in the given number group must be used only once. For example, if the extracted 4 face numbers of the calculated card set are 3, 4, 4, and 9, respectively, then the given number set is (3, 4, 4, and 9), and the result is 24 as calculated by the equation (9 ÷ 3) × (4 + 4).

This conventional way of drawing 4 playing cards to obtain a given set of numbers as described above is not conducive to the development and promotion of a "calculate 24 points" puzzle under multiple scenarios. Firstly, a large space is needed for placing 4 cards, which has high requirements on the game environment, and if the space is limited, the playing is difficult. Secondly, the placing and displaying time of 4 cards is difficult to control and synchronize, and under the scene of competitive participation of a plurality of people (for example, two people play a common game, each person draws two cards and requires to put down and display the cards to the other side at the same time), some players can see all card groups first due to the lag of part of the playing card display, so that unfair competition is caused. In addition, not all the extracted calculation card sets can meet the requirement of successfully completing the 24-point calculation, for example, (6, 7, 7, 9) cannot obtain 24 through addition, subtraction, multiplication and division calculation, and such card sets often consume a lot of time for the participants to try and then are forced to be frustrated and abandoned, so that the participants cannot obtain a sense of achievement, and the enthusiasm of the participants is influenced. The computational difficulty of the last many given sets of numbers that successfully complete the "calculate 24 points" is also different. For example, there are a number of ways to calculate the result 24 for a given set of numbers (4, 6, 6, 8) that is suitable for use by children of low age; given the number groups (3, 3, 8, 8) it is necessary to know the score to calculate the result 24, which is suitable for the participants of higher ages. The method of extracting the playing cards to obtain the given number group is difficult to control the calculation difficulty of the extracted card group, and is not beneficial to the popularization of the '24-point-counting' game.

Disclosure of Invention

The invention aims to provide a novel card tool for calculating 24 points, which is convenient for a participant to use and improves the experience of the participant, wherein each card is provided with a group of all 4 given numbers which can successfully finish calculating 24 points, so that the problems of high occupied placing space requirement, unsynchronized number display, incapability of successfully finishing calculating 24 points, difficulty in developing reasonable calculation difficulty grouping and the like caused by a mode of extracting 4 playing cards to obtain a given number group for calculating 24 points are solved.

The invention adopts the technical scheme that a novel card tool for calculating 24 points is provided, and one card tool set can contain a plurality of cards. Each card is in a flat rectangular sheet shape, and the material of each card can be paper, plastic or metal. The card face provides all 4 given numbers required to make a "24 o 'clock" calculation and ensures that this given set of numbers is able to successfully complete the "24 o' clock" calculation. The '24-point-counting' intelligence-developing game can be developed by only one card, and the participator can conveniently play the game even if holding the card by hand without the limitation of the placing space. By providing all 4 given numbers on the same side of the card that are required to "count 24" once, the lack of sequential synchronization of the number presentation is avoided. The "count 24" requirement is successfully met by ensuring that a given set of digits for each card has been verified, avoiding ineffective attempts by the players and increasing player success. Meanwhile, 24-point calculation difficulty information of the card is provided on the card by adopting a color prompt method or a symbol prompt method, so that the participant is helped to screen proper cards in advance or carry out differentiation scoring according to different calculation difficulties, and the applicability and the playability of 24-point calculation are enriched. The card tool can select one or a plurality of cards with specific difficulty to be packaged independently according to different target use objects.

The card special for counting 24 points has the advantages that all 4 given numbers required for counting 24 points once are provided on a single card, the given number group can be ensured to successfully finish counting 24 points, and the scene applicability and the participant achievement sense for developing the 24-point counting intelligence-improving game are effectively improved. By providing the calculation difficulty prompt information of '24 points' on the cards, school teachers and parents can be helped to conveniently select the card group with reasonable difficulty of '24 points' for being provided for children of low ages to use, and the effect of improving mental calculation capacity of the children by the '24 points' intelligence developmental games is realized more accurately. Meanwhile, the calculation difficulty prompt information can be used for differentiated scoring, and the game rule of 'calculating 24 points' is enriched, so that the playability of the 'calculating 24 points' game is enhanced. The improvement is beneficial to the popularization and the promotion of the '24-point-counting' intelligence developmental game and is more beneficial to playing the beneficial effect of improving the mental calculation ability of the participants of the game, thereby having great popularization prospect.

Detailed Description

The user can use the card special for calculating 24 o 'clock of the invention independently, draw the card and calculate 24 o' clock for each card, and exercise the calculation ability and the digital sensitivity of the user. The card quantity successfully completing the 24-point calculation within a fixed time can be used as a measuring basis, and differentiation scoring can also be performed according to the calculation difficulty prompt information of the cards, for example, the card with the lowest difficulty completes one score at a time, the card with the higher difficulty completes one score at a time, and the like.

(embodiment 2) a plurality of 'count 24 points' game participants can conveniently play competitive games by using the 'count 24 points' special cards, and the participants can conveniently play the competitive games by only holding the cards with hands without additional fields for placing the cards. The card is presented simultaneously on the front of all players, the first successful responder wins and wins the card. After the game is finished, the participator calculates scores according to the won cards, namely, one card counts one score, or carries out differentiation scoring according to the calculation difficulty prompt information of the cards.
