Abstract

Mathematical dominoes have a mathematical sum, such as an addition, subtraction, multiplication, division or any other compound mathematical function on each half of the two domino-halves on every domino piece. The matching process is facilitated by 'split- markers' that are in the form of a colour, shape, design or numeral that only forms a complete picture or a recogniseable numeral if the correct domino-halves have been matched. This acts as a checking device. <IMAGE>

Description

SPECIFICATION Mathematical domino game This invention relates to a domino game.

Domino is a well known game which is played by one or several players using rectangular pieces that are placed alongside each other to conform to a prescribed plan or pattern.

According to the present invention each domino piece is divided into two halves by a vertical line and each half is hereby referred to as a 'DOMINO-HALF'. Each domino-half has a mathematical sum in the form of a multiplication, addition subtraction or a division or any other function like a square root or a compound function with an END RESULT. The object of the game is to find another dominohalf on which the end result of the mathematical sum is the same and may be matched and placed alongside each other in the usual way of domino-half alongside domino-half.

According to the present invention each domino-half is provided with a 'split-marker' in the form of a part-numeral, part-picture, part-sign or part-colour which can only be fitted to one other specific domino-half and when the TWO 'split-markers' meet only then do they become recognisable as a numeral, shape or picture which will also co-incide with the results of the two domino-halves being correct. These 'split-markers' act as a further checking system so that the correct dominohalves have been matched and ensures at the same time continuity of the game till all the pieces have been placed out in their correct positions because the 'split-markers' are preplanned to form a continuous chain, no matter which piece started the domino game.

The purpose of the invention is to offer learning and practice to people of all ages in mathematics at various levels, in the form of a game which can be made into simple sums for children and harder sums for adults or anyone with advanced knowledge according to their ability.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which: Figure 1 shows in perspective, the domino game during play; Figure 2 shows the function of the 'splitmarkers'; Figure 3 shows the problem when two domino-halves may be matched to another, but only one 'split-marker' is correct; Figure 4 shows the two sided domino; Figure 5 shows the four sided domino; Referring to the drawings the Mathematical Domino Game may proceed as in Fig. 1.

placing correct end result on domino-half alongside correct end result on another domino-half making sure that the 'split-markers' are also matching as illustrated by examples 10. and emphasising the function of the 'splitmarkers' as a checking device and as a safeguard to continuity as illustrated in Fig. 2 by examples 11.

The problem of two or more domino-halves capable of being matched to the one already in play as illustrated in Fig. 3 by dominoes 12, 13, 14 and 1 5 is overcome by the 'splitmarkers' that ensures that here only one domino fits by completing the two halves of the 'split-markers' into a recognisable entity as illustrated by Fig. 3 dominoes 12. and 15.

Fig. 4 and Fig. 5 illustrate that one domino piece may have both faces marked with sums to constitute Two separate games as illustrated in Fig. 4. Top Face(in play) 1 6 and Bottom Face (not in play) 1 7.

Fig. 5. finally illustrates a four sided domino, where four separate games of differing levels may be constructed as shown by Top Face (in play) 18 Front Face(not in play) 19 Bottom Face (not in play) 20 and Rear Face (not in play) 21.

1. The Mathematical Domino Game is designed to teach and give practice in mathematics to learners and more advanced students in the form of a domino game whereby one has to work out the mathematical answer on the domino-half on the table that is in play and match it with another domino which has the same mathematical answer.

2. The 'split-markers' on the dominohalves are designed to prevent the game from getting 'stuck', where more than one dominoes may be matched 'Mathematically' but only one domino with the Right 'split-marker' ensures continuity. The 'split-markers' also act as a checking device that the mathamatical sum has also been matched correctly.

3. The Double Sided domino is designed for two separate games of differing levels as described in Claim 1 and Claim 2 and the two sides of the dominoes may clearly be distinguished by colour and design.

4. The Four Sided domino is an extension of Claim 1 Claim 2 and Claim 3 in that four separate games may be designed and played and each of the four domino faces may be distinguishable by colour or by design.
