Phonics breakdown
Phonics Rule: SL Blend
S and L blend together — you hear both sounds! Like in 'slow' and 'sleep'.
The blend SL combines /s/ and /l/ spoken quickly together.
Examples
Phonics Rule: OW (Long O Sound)
OW sometimes says long O, like in 'snow' and 'show'.
The spelling 'ow' can make the long O sound /oʊ/, especially at the end of a word. It can also make the /aʊ/ diphthong sound (like 'cow').
Tip
Snow falls slow — OW says long O!
Examples
Phonics Rule: Suffix -EST
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.
