Module 18 ‘-sure’ is given as a regular final syllable and pupils are taught to recognise the subtle differences between the phonics at the end of ‘measure’ and ‘pressure’. The letters ‘ei’ are given as the ninth and final spelling choice for the long vowel sound (e) as in ‘receive’ and pupils are taught that the same letters can make the long vowel sound (a) as in reindeer, but this is a relatively small group of words. The spelling choice ‘ph’ is taught and pupils learn that these words often have a scientific or technical meaning. The spelling choice ‘-our’ is given and taught that the majority of these words are two syllables, with the second syllable being unstressed (er) as in ‘favour’, ‘rumour’ and ‘splendour’. Multi-syllabic words such as ‘dishonourable’ are two syllable root words with prefix and suffix added. Star Skill 90 gives the letters ‘eigh’ as the eighth and final spelling choice for the long vowel sound (a).
