The recognition and understanding of percentages can be helped by the use of this set of 24 plastic dominoes in which percentages are expressed as both vulgar and decimal fractions.

The game may be played by 2, 3 or 4 players. Each player first selects an equal number of dominoes then takes turns to start the game by playing any domino held. The game proceeds as for ordinary dominoes, connecting the pieces in line or at right angles as desired. If no connecting domino is held the player misses a turn. The winner is the first player to place all dominoes held.
