Phase 3 introduces children to the remaining, more difficult and/or less commonly used phonemes. There are around 25 of these, depending on which scheme is followed, mainly made up of two letters such as /ch/, /ar/, /ow/ and /ee/. They learn the names of the letters, as well as the sounds they make. Activities might include learning mnemonics (memory aids) for tricky words, practising writing letters on mini whiteboards, using word cards and singing songs like the Alphabet Song.
Phase 3 takes most children around 12 weeks. By the end, they should be able to say the sound made by most, or all, Phase 2 and 3 graphemes, blend and read CVC words made from these graphemes, read 12 new tricky words and write letters correctly when given an example to copy.
