These charts have been designed to increase understanding of the complex spelling system of the English language. Whilst Alphabet Posters show the 26 upper case (capital) and 26 lower case letter shapes teaching letter knowledge, alphabetical order and handwriting, in contrast Alphabetic Code Charts illustrate the smallest sounds of speech (phonemes and combined phonemes) linked to the graphemes (letters and letter groups) which ARE CODE FOR the sounds. Alphabetic Code Charts support the teaching and learning of the many letter/s-sound correspondences of the alphabetic code for reading and spelling.
