Phonics breakdown
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: STR Blend
S, T, and R blend together — you hear all three! Like in 'strong' and 'street'.
STR is a three-letter consonant blend. You hear /s/, /t/, and /r/ spoken quickly together. It always appears at the beginning of a word.
Examples
Phonics Rule: Schwa
In unstressed syllables, vowels often make a lazy 'uh' sound called schwa, like the A in 'about'.
Schwa /ə/ is the most common vowel sound in English. Any vowel letter can make the schwa sound when it's in an unstressed syllable. It sounds like a quick, lazy 'uh'.
Tip
Schwa is lazy — any vowel can say 'uh' when it's not stressed!
Examples
Phonics Rule: PH Digraph
PH makes the /f/ sound, like in 'phone' and 'photo'. It comes from Greek!
The digraph 'ph' always makes the /f/ sound. These words usually come from Greek. If you see PH, just say /f/.
Tip
PH phones home with an /f/ sound!
Examples
Phonics Rule: Y as Long I
When Y is at the end of a short word, it says long I, like in 'fly' and 'cry'.
When Y appears at the end of a single-syllable word, it makes the long I sound /aɪ/. Examples: fly, cry, by, my, sky, dry, try.
Tip
Y at the end of a short word says I — fly, cry, sky!
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: Open Syllable I (Long I)
When I is the last letter of a syllable, the syllable is open and the I says its name /aɪ/ — like in 'hi' and 'fi-nal'.
This is the open-syllable pattern: a syllable that ends in a vowel leaves it 'open', so it says its long name. Here, a lone I at the end of a syllable says /aɪ/ (hi, si-lent). The I also says its long name before two consonants in the 'ind' and 'ild' families (find, kind, child, mild). The long I sound is also spelled other ways, each its own rule — silent E (bike) or igh (night) — but those are not open syllables.
Tip
Long I says its name — I!
Examples
Phonics Rule: Hard C
C makes the /k/ sound before A, O, U, or a consonant, like in 'cat' and 'cup'.
The letter C makes the hard /k/ sound when followed by A, O, U, or a consonant. This is the default C sound. Examples: cat, cup, coat, cold, crab, class.
Tip
C says K before A, O, U — cat, cup, coat!
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: Letter L
The letter L makes the /l/ sound, like in 'lamp', 'leg', and 'lip'. The tongue tip touches behind the upper teeth.
L is a voiced lateral approximant — the tongue tip touches the ridge behind the upper teeth while air flows around the sides. Double L (ll) makes the same /l/ sound.
Tip
L is for lamp — light it up with /l/!
