Abstract

Dice game comprising a set of dice in the form of regular polyhedrons, e.g. cubes, octahedrons, dodecahedrons and icosahedrons, with numbers (1-10 and the sign X), letters (A-U) or different colours on their sides. An exercice book is provided containing mathematical problems, which can be selected and solved by rolling the dice. The dice and exercice book can be written in Braille, allowing blind people to participate in the game. Alternatively, the dice can be marked with card signs, allowing classical card games to be played.

Description

GAME OF DICES

This invention is about a dice game with dices,having the form of perfectly regular polyhedrons, with the help of which problems of elementary Mathematics ,can be solved,playing without paper or pencil,both for sighted and for blinds.

There are known many card games,logical games including different geometrical corps: spheres,pyramides or their combinations,with or without mobil units.

The disavantage of cards game is playing with a great number of cards,that means a game space,and there is the posibility of cheating.The disavantage of logical games is the lack of possibilities,being boring after a short period of time,many of them are complicated being played only by professional players,must of the cases developing only the logical thinking. The field of this type of games for blinds is almost out of the question.

The games of dices,according to the invention eliminates the disavantage of the know games,being realized by a set of dices having the form of perfectly regular polyhedrons: octahedron,dodecahedron, icosahedron and eventually cube,with the sides written with numbers from 0....10 and sign "X" the 12 pentagonal sides( b,b') of the dodecahedron, the sum of the opposite side must be 11, with the letters from A....U the 20 triangular sides (c,c') of the icosahedron and with 8 basic colours on the eight triangular sides (a,a') of the octahedron.For blinds,inscriptions of letters and numbers is made by proeminent or forming gaps,using Braille writing,and on the eight triangular sides ( a') of the octhaedron are sticked eight different tissues having the same colour like for the sighted.To use this game as a teaching aid for the gradual learning of the fundamental mathematical notions,especially for blinds ,the cube may replace the icosahedron which has on the six sides (d,d') the letters from A....F or it is replaced by another octahedron whose eight sides have the letters from A....H written on them .The number of the dices in the game depend ori the rules and the variants of the game/ or on the number of Mathematics problems which are to be solved during the game.The Mathematics problems are in a exercise book attached the game.

The game of dices presents the following advantages: -it has a duble role:is in the same time a pedagogical and a game for fun,for solving mathematic problems without sing a pen or a sheet of paper, -contains problems which are connected with the elementary curriculum,namely rules of arithmetic(summation,subtraction,multiplication and division),equations,inequalities,theory of sets(unions,subtraction,section, containment).

-having the possibility to realize a great number of game variants.

-it doesn't limit the number of the players,it can be played everywhere.

-it is accesible to a large cathegory of players ,both sighted and blinds.

-it approaches the solving of mathematics problems from a new point of view,placing the accent on the logical thinking.

-it models the real life,encourages and help develop interactivity, rivary,initiative,creativity,quik and logical thinking.

-it can be corelated to school analytic programmes.

-it is a new game,simple,rapid and useful.

-it doesn't need sofisticaated and expensive technologies.

-it is an interesting and complex game,it doesn't become boring, because mathematics problems can be replaced by another ones,changing only the exercise-book with problems.

-it can be constructed by paper at home,it's available for everyone.

-it is competitive with all of this kind of games from the market.

-it made contact between sighted people and blinds,it makes children become fond of mathematics.

There are two exemples,helped by the figures 1,2,3,4,5,6,7,8, 9,10,11 and 12.

-Fig.12. -represents the unfolded cube the 6 squares sided ,written with letters from A....F,using in Braille.

1.This game of dices,according to the invention,for sighted,contains by a set of dices having the form of some perfectly regular polihedrons: 1 piece octahedron(fϊg.l .),5 pieces dodecahedron(fig.4),l pieces icosahedron(fig.7.), 1 exercise book with unsolved problems and 50 counter discs for awarding right solutions. One color and one letter determine one problem in the exercise-book.The problems can be of two types :substituing or theory of sets.Problems solving means to choose and substitute of numbers resulted by rolling the dodecahedrons dices,whose sides (b,b') are written with numbers from 0...10 and the sign "X",having the role of a "jolly-joker",it can substitute any numbers.For each good answer you get a counter-disc. At the end of the game ,the person who has more counter-discs is the winner. With this kind of dices combination, 160 problems can be solved, without changing the exercise-book. When the game is used as a teaching aid for gradual learning of elementary mathematics notions,the dices having the form of a icosahedron is substituited by a cube,whose sides have letters,48 problems being solved,or by another octahedron, with letters from A....H on the sides,64 different types of problems being solved.

2. This game of dices,according to the invention,for blinds,contains 7 dices having the form of polihedrons like in example l .,the sides have proeminent letters and numbers,using in Braille,on the 8 sides of the octahedron are sticked 8 different tissues,maintaining the coulours in order that people blinds can play with people sight same mathematics problem to solve,the blinds using the exercise-book written in Braille.When this game is used as a teaching aid,for gradual learning of elementary mathematical notions,which is very important for blinds,the icosahedron dice with letters is substituted by octahedron or by cube with letters,using Braille letters from A....H,and respectevly from A... F.

There are many variants of the game,the number of dices and their combinations depend on the problems to be solved during the game and/or on the variants of the game. In order not to become boring,after being payed by the same payers,the exercise-book can be substituted,changing the problems,without changing the dices set.If the octahedrons triangle sides will wear playing cards signs,the dices can substituted classic card- games,such as hazard ous games.
