ABSTRACT:
A moulded plastics casing comprising a lid and a base accommodates two moulded plastics rotatable spools formed with projecting operating knobs. A roll of flexible plastics material or paper having letters of the alphabet printed thereon is provided on one of the spools and has its free end engaged within a slot in the other spool so that the letters can be viewed through a reading window in the lid. The letters are arranged in a series of lines parallel to the axes of rotation of the spools and the lines form sets such that, as the lines of a set are viewed successively and one at a time through the reading window by turning one of the operating knobs, a word is progressively built up within the reading window. As each line appears in the window the letter or letters on that line should be sounded (reading) or the names of the letters recited (spelling). The words on the roll are related to one another by having sounds in common so as to form a "phonic progression". Other phonic progressions are formed on further rolls which may be inserted in the aid in place of the existing roll.
