Phonics breakdown
Phonics Rule: ST Blend
S and T blend together — you hear both sounds! Like in 'stop' and 'fast'.
The blend ST combines /s/ and /t/ spoken quickly together. It can appear at the beginning or end of a word.
Examples
Phonics Rule: Short A
The letter A makes a short sound, like in 'cat' and 'bat'.
When the letter A appears in a closed syllable (a syllable that ends with a consonant), it usually makes the short A sound /æ/. This is one of the first vowel sounds students learn.
Tip
A says /æ/ like a cat that sat on a mat.
Examples
Phonics Rule: CK Digraph
CK together makes the /k/ sound, like in 'back' and 'kick'.
The digraph 'ck' appears right after a short vowel at the end of a one-syllable word. If the vowel is short, use CK. If the vowel is long, use just K (like 'make').
Tip
Short vowel? CK comes quick — back, kick, duck!
Examples
Phonics Rule: Plural -S (/s/ sound)
Adding -S makes a word plural (more than one). After unvoiced sounds, -S says /s/, like 'cats'.
The plural -s says /s/ after unvoiced consonants (p, t, k, f, th). Like -ed, the pronunciation depends on the final sound of the base word.
