b show how the fraction number is formed two tiles numerator and denominator form the fraction as they are attached to fraction joiner that covers their non active sides additional tile integer number can be added in front of the fraction by attaching fig7 shows tile guard standard game set contains 4 such guards it allows the players to keep the tiles organized and hidden from other players the guard is composed of two non flat plates base plate and resting plate resting plate is located approximately 80 degrees to the base plate to allow the tiles to lean against the resting plate height should be approximately 75 of the tile size to allow tiles to rest firmly and allow other players to see number of tiles the player owns see guide with tiles in fig1 base plate should be wide enough to accommodate 3 tiles stack together and leaning against the resting plate a fig8 a shows the forward move the player attaches his number 2 to a number from the table 4 matching the same math sign sides creating math operation then he she attaches to the added number another number 2 that is the result of the created math operation matching u201c u201d sides b fig8 b shows the backward move the joins two his numbers 7 and 3 with sides of the same math sign creating math operation then he attaches the created assembly to the number from the table 4 that is the result of the math operation matching u201c u201d sides c fig8 c shows the split operation move the player attaches one his numbers 1 to the.
