Phonics breakdown
Phonics Rule: PL Blend
Sound“pl”·/pl/
P and L blend together — you hear both sounds! Like in 'play' and 'plan'.
The blend PL combines /p/ and /l/ spoken quickly together.
Examples
When the letter A appears in a closed syllable (a syllable that ends with a consonant), it usually makes the short A sound “a”. This is one of the first vowel sounds students learn.
Tip
A says “a” like a cat that sat on a mat.
Examples
Phonics Rule: Letter N
Sound“n”·/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: Open Syllable E (Long E)
Sound“ee”·/iː/
When E is the last letter of a syllable, the syllable is open and the E says its name “ee” — 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 “ee” (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: Letter T
Sound“t”·/t/
The letter T makes the /t/ sound, like in 'top', 'tap', and 'ten'. The tongue tip taps behind the upper teeth.
T is a voiceless alveolar stop. The tongue tip touches the ridge behind the upper teeth and releases with a puff of air. Double T (tt) makes the same /t/ sound.
Tip
T taps — touch your tongue to make /t/!
Examples
Phonics Rule: R-Controlled AR
Sound“ar”·/ɑːr/
When R comes after A, it changes the sound to “ar”, like in 'car' and 'star'.
When A is followed by R, the R 'bosses' the vowel and changes its sound. Instead of short A or long A, you hear “ar”. R-controlled vowels are sometimes called 'Bossy R'.
Tip
Bossy R takes the car to the farm!
Examples
Phonics Rule: Open Syllable E (Long E)
Sound“ee”·/iː/
When E is the last letter of a syllable, the syllable is open and the E says its name “ee” — 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 “ee” (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: Schwa
Sound“uh”·/ə/
In unstressed syllables, vowels often make a lazy 'uh' sound called schwa, like the A in 'about'.
Schwa “uh” 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 M
Sound“m”·/m/
The letter M makes the /m/ sound, like in 'map', 'mud', and 'mop'. Both lips press together with voice through the nose.
M is a voiced bilabial nasal — both lips press together while the voice hums through the nose. Double M (mm) makes the same /m/ sound.
Tip
M hums like mmm — press your lips and hum!
