Phonics breakdown
Phonics Rule: Short I
The letter I makes a short sound, like in 'sit' and 'big'.
When the letter I appears in a closed syllable, it usually makes the short I sound /ɪ/. This is one of the trickiest short vowels because it sounds similar to short E.
Tip
I says /ɪ/ like an itch you can't miss.
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!
Examples
Phonics Rule: Letter V
The letter V makes the /v/ sound, like in 'van', 'vet', and 'vine'. Upper teeth touch the lower lip with voice.
V is a voiced labiodental fricative — the upper front teeth rest on the lower lip while air and voice flow through. It is the voiced partner of F. English words rarely end in V; they usually add an E (have, live, give).
Tip
V is for van — /v/ vibrates your lips!
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: Suffix -SION (/zhun/)
After a vowel, -SION buzzes to /zhun/, like in 'vision' and 'division'.
When -SION follows a vowel, it makes the voiced /ʒən/ (zhun) sound: vision, division, confusion, explosion, invasion. (After a consonant it says /ʃən/ instead — mission, tension — see the companion rule.)
Tip
-SION after a vowel buzzes — a vision of division!
