A writing training aid comprising a writing training kit for use in training persons to write. The writing training kit includes a planar member (10) having at least one slot (20) formed therein that defines a symbol which the person is to be trained to form in writing. The writing training kit includes an elongate body representing a writing instrument. The planar member has entrance and exit openings (22, 24) defined therein which lead into the slot (20) and which define initiation and termination positions, respectively, for the symbol to be formed. The planar member and the elongate body are configured to permit insertion of an end of the elongate body into an entrance opening, displacement of the elongate body along the slot and removal of the elongate body from an exit opening but to prevent removal of the elongate body from the slot intermediate the entrance and exit openings.
