Phonics breakdown
Phonics Rule: Letter D
The letter D makes the /d/ sound, like in 'dog', 'day', and 'dig'. The tongue tip touches behind the upper teeth.
D is a voiced alveolar stop. The tongue tip touches the ridge just behind the upper front teeth, then releases with voice. It reliably makes the /d/ sound in almost all positions.
Tip
D is for dog — and dog starts with /d/!
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: 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: CH Digraph (/k/ sound)
In some words from Greek, CH makes the /k/ sound, like in 'chorus' and 'chemistry'.
When CH comes from a Greek-origin word, it says /k/ instead of /tʃ/. Common examples include words related to music (chorus, chord), science (chemistry, chrome), and character. These words must be learned.
Tip
CH in Greek words sounds like K — chemistry, chorus, character!
Examples
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: 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: Letter N
The letter N makes the /n/ sound, like in 'net', 'nap', and 'nut'. The tongue tip touches behind the upper teeth.
N is a voiced alveolar nasal — the tongue tip touches the ridge behind the upper teeth while voice hums through the nose. It is one of the most common consonants in English.
Tip
N hums through the nose — say /n/ and feel the buzz!

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 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!
