Phonics breakdown
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 B
The letter B makes the /b/ sound, like in 'bat', 'big', and 'bug'. Both lips press together then release.
B is a voiced bilabial stop — both lips press together and release with voice. It always makes the /b/ sound except when silent at the end of words after m (as in 'lamb' or 'comb').
Tip
B looks like a bat — and bat starts with /b/!
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: Short E
The letter E makes a short sound, like in 'bed' and 'red'.
When the letter E appears in a closed syllable, it usually makes the short E sound /ɛ/. This is often confused with short I by new readers.
Tip
E says /ɛ/ like an egg on your head.
Examples
Phonics Rule: Letter P
The letter P makes the /p/ sound, like in 'pan', 'pig', and 'pot'. Both lips press together then pop open.
P is a voiceless bilabial stop — both lips press together and release with a puff of air but no voice. It pairs with B (which is the voiced version of the same mouth position).
Tip
P pops open — press your lips and let it POP!
Examples
Phonics Rule: R-Controlled ER
When R comes after E, it makes the /ɜːr/ sound, like in 'her' and 'fern'.
ER makes the same sound as IR and UR — they all say /ɜːr/. ER is the most common spelling of this sound, especially at the end of words.
Tip
ER, IR, and UR all sound the same — Bossy R wins again!
Examples
Phonics Rule: OU says /ə/ (-ous)
OU says the lazy schwa /ə/ in the ending -OUS, like in 'famous' and 'generous'.
In the suffix -ous, OU is unstressed and says schwa /ə/: famous, generous, nervous, dangerous, enormous.
Tip
- OUS is famous for the lazy uh — famous, nervous!
Examples
Phonics Rule: Plural -S (/z/ sound)
After voiced sounds, -S says /z/, like in 'dogs' and 'birds'.
After voiced consonants and vowels, the plural -s says /z/. Most people don't notice this — it sounds natural.
