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: Open Syllable A (Long A)
When A is the last letter of a syllable, the syllable is open and the A says its name /eɪ/ — like in 'ba-by' and 'pa-per'.
This is the open-syllable pattern: a syllable that ends in a vowel leaves that vowel 'open', so it says its long name. Here, a lone A at the end of a syllable says /eɪ/ (ba-by, a-pron, lady). The long A sound is also spelled other ways, each its own rule — silent E (cake), or vowel teams (ai in rain, ay in play) — but those are not open syllables.
Tip
Long A says its name — A!
Examples
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 E (Long E)
When E is the last letter of a syllable, the syllable is open and the E says its name /iː/ — like in 'he' and 'me'.
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 E at the end of a syllable says /iː/ (he, me, we, be). The long E sound is also spelled other ways, each its own rule — vowel teams (ee in tree, ea in read) — but those are not open syllables.
Tip
Long E says its name — E!
Examples
Phonics Rule: Open Syllable O (Long O)
When O is the last letter of a syllable, the syllable is open and the O says its name /oʊ/ — like in 'go' and 'no'.
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 O at the end of a syllable says /oʊ/ (go, no, so, o-pen). The O also says its long name in the 'old' and 'ost' families (cold, most). The long O sound is also spelled other ways, each its own rule — silent E (home) or vowel teams (oa in boat, ow in snow) — but those are not open syllables.
Tip
Long O says its name — O!
