Phonics breakdown
Phonics Rule: Letter F
The letter F makes the /f/ sound, like in 'fish', 'fun', and 'fox'. The upper teeth touch the lower lip.
F is a voiceless labiodental fricative — the upper front teeth rest on the lower lip while air flows through to make the /f/ sound. It is very consistent.
Tip
F is for fish — and fish starts with /f/!
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 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: Silent T
Sometimes the T is silent — you don't say it, like in 'listen', 'castle', and 'often'.
In some words the T is silent. You see it, but you don't say it. This happens most in words ending -stle and -sten (castle, whistle, listen, fasten) and in 'often' and 'Christmas'.
Tip
Shh — the T is silent when you listen in the castle!
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!
