Our school, along side a speech pathologist, have sorted the oxford sight words into sounds which support the jolly phonics program. There are 7 phases of words that can be sounded out and follow the introduction of sounds jolly phonics uses. There are 100 tricky words which can not be sounded out and follow different 'rule' patterns. There are also 9 other groups which follow other sound patterns, igh, ay, c=s etc. I have created a checklist/assessment form which list all the words which you can purchase from my store.
