Abstract: The invention comprises three-dimensional characters, i.e., letters and/or numerals, which have discretely colored indicia thereon to distinguish left-hand and right-hand sides of the characters, so that a student of writing and/or reading will know how to position each character to dispose the same in a correct orientation. In this, one colored indicia must always be at the left-hand side, and the other colored indicia must always be at the right-hand side. Included is a color-coded guide in which, slidably, to set the characters; the coloring of the guide complements the left- and right-hand colored indicia of the characters.
