In Level 5 - Green, children will learn new graphemes and alternative pronunciations for known graphemes. For example, they have already learned /ow/ as in 'cow' and will now learn /ow/ as in 'blow'. In addition, they will learn alternative spelling for known phonemes. For example, the sound /igh/ as been taught as the grapheme igh as in 'night', but can also be spelled 'y', 'ie', and 'i-e'.
