Phonics breakdown
Phonics Rule: SM Blend
Sound“sm”·/sm/
S and M blend together — you hear both sounds! Like in 'small' and 'smile'.
The blend SM combines /s/ and /m/ spoken quickly together.
Examples
Phonics Rule: OO (Long Sound)
Sound“oo”·/uː/
OO often makes the long sound, like in 'moon' and 'food'.
The vowel team 'oo' has two sounds. The long sound “oo” is more common and appears in words like 'moon', 'food', and 'school'.
Tip
OO like the moon — ooooo!
Examples
Phonics Rule: TH Digraph (Voiced)
Sound“th”·/ð/
TH can make a buzzy sound “th”, like in 'this' and 'the'. You can feel your throat vibrate!
The voiced TH “th” is the vibrating version. Put your hand on your throat — you can feel it buzz. This sound appears in very common words like 'the', 'this', 'that', 'they'.
Tip
Voiced TH buzzes — this, that, the!
Examples
Phonics Rule: Suffix -EST
Sound“ist”·/ɪst/
Adding -EST means 'the most', like 'biggest' and 'fastest'.
The suffix -est makes a superlative — it means 'the most' of something. 'Big' → 'biggest' means the most big of all.
