Abstract: The present invention is an electronic learning aid which employs a scanning device for reading printed coded indicia which includes random number modes. A first random number mode provides a flat distribution random number in accordance to a range command. This mode is actuated by scanning coded indicia, firstly, a random number generation command and secondly, a range command. The apparatus then generates a random number from a set of numbers, this set of numbers being determined by the range command.
