All the capital letters of the alphabet may be written using several basic strokes, straight and curved, common to each letter. The straight lines may be vertical, horizontal or diagonal. The curved lines may take various directions, or be closed, as with the « O ». This box contains a small series of these lines in soft plastic, with which a child can arrange every capital letter of the alphabet. He will learn, for instance, that the « R » is formed by a vertical, a curved and a diagonal line; that the « D » is formed by a vertical and a large curved line, etc. After learning the alphabet he may enjoy using more elements to make larger letters and a variety of other shapes.
