Phonics breakdown
Phonics Rule: Letter R
The letter R makes the /r/ sound, like in 'run', 'red', and 'rope'. The tongue curls back slightly.
R is a voiced approximant. The tongue curls back or bunches up without touching the roof of the mouth. When R follows a vowel it changes that vowel's sound (r-controlled vowels).
Tip
R is for run — /r/ with a curl of the tongue!
Examples
Phonics Rule: Short U
The letter U makes a short sound, like in 'cup' and 'bus'.
When the letter U appears in a closed syllable, it usually makes the short U sound /ʌ/. This sounds like 'uh'.
Tip
U says /ʌ/ like 'uh-oh, what's up?'
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: Letter S
The letter S usually makes the /s/ sound, like in 'sun', 'sit', and 'sock'. Air hisses through a small gap.
S is a voiceless alveolar fricative when it makes the /s/ sound. At the end of many words it can also make a /z/ sound (as in 'dogs' or 'has'). At the start of a word it is always /s/.
Tip
S hisses like a snake — sssssun!
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!
