The purpose of this phase is for children to broaden their knowledge of graphemes and phonemes for use in reading and spelling. Children will learn  alternative pronunciations for graphemes they already know. Some of the alternatives will already have been encountered in the high-frequency words that have been taught. Children become quicker at recognising graphemes of more than one letter in words and at blending the phonemes they represent. When spelling words they will learn to choose the appropriate graphemes to represent phonemes and begin to build word-specific knowledge of the spellings of words.
