Abstract: A system is described which comprises a set of complementary charts for teaching and testing word pronunciation and spelling. The set includes a first chart whereupon symbols representing vowel and consonant sounds, are disposed along respective orthogonal edges of a carrier. Positioned at the juncture of imaginary columns and rows emanating from each sound symbol are entries which are sounded by the combination of the corresponding consonant and vowel sounds.A second chart is provided for test purposes whereupon symbols representing the same vowel and consonant sounds as the first chart are disposed along the same orthogonal edges. Having worked with and studied the first chart, the student is instructed to write in at the juncture of the imaginary columns and rows, or on a separate sheet of paper words which are sounded by the combination of the corresponding consonant and vowel sounds.
