When children start Phase 4 of the Letters and Sounds phonics programme, they will know a grapheme for each of the 42 phonemes. They will be able to blend phonemes to read CVC (consonant-vowel-consonant) words and segment in order to spell them.
Children will also have begun reading straightforward two-syllable words and simple captions, as well as reading and spelling some tricky words.
In Phase 4, no new graphemes are introduced. The main aim of this phase is to consolidate the children's knowledge and to help them learn to read and spell words which have adjacent consonants, such as trap, string and milk.
