Oz Phonics 4 has 5 lesson groups that build on the content of the Oz Phonics Intro, 1, 2 and 3 apps. Lesson group 1 introduces some new sound/letter relationships. The ‘c’ making the /s/ sound, as in ‘city’. The ‘g’ making the /j/ sound, as as in ‘gentle’. The /ng/ sound at the end of the word ‘ring’ is also introduced, with the letter ‘n’ by itself, also making this sound, as in the word ‘bank’. Lesson groups 2, 3, and 4 introduce the long vowel sounds(letter name sounds) and some of their spellings. These 3 lesson groups also follow the same format as lesson group 1, demonstration, missing letter exercise, word finder, reading practice. More long vowel spellings will be covered in the Oz Phonics 5 app. Lesson group 2 covers ‘letters by themselves” in a word (/long a/ sound in the word baby, /long e/ in the word ‘be', etc.). Lesson 3 covers “letters with an ‘e’ separated by a consonant” (tape, note, cube, etc.). Note that the ‘u-e’ combination produces two different sounds, /oo/ in ‘nude’ and /yoo/ on ‘cube’. Lesson group 4 covers “letters next to an ‘e’” (pie, bee, toe, blue). Also included is the ‘ye’ making the long ‘I’ sound as in the word ‘bye’. Lesson group 5 introduces r-Controlled Vowels. ‘er’, ‘ir’, ‘ur’ all making the same sound, and the sounds ‘ar’ and ‘or’. Visit ozphonics.com for details of other apps in our step-by-step series.
