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 U — /uː/ (Long U)
In an open syllable, when U follows L, R, S, or J it says 'oo' instead of 'yoo' — like in 'su-per' and 'tru-ly'.
Same open-syllable pattern as the companion Open Syllable U (/juː/) rule, but when the lone U follows L, R, S, or J it drops the Y-glide and says pure /uː/ (su-per, ru-by, tru-ly). Same letter, different sound depending on what comes before it.
Tip
After L, R, S, J — U says oo, not yoo!
Examples
Phonics Rule: Letter L
The letter L makes the /l/ sound, like in 'lamp', 'leg', and 'lip'. The tongue tip touches behind the upper teeth.
L is a voiced lateral approximant — the tongue tip touches the ridge behind the upper teeth while air flows around the sides. Double L (ll) makes the same /l/ sound.
Tip
L is for lamp — light it up with /l/!
Examples
Phonics Rule: Suffix -ER
Adding -ER can mean 'more' (bigger) or 'a person who' (teacher).
The suffix -er has two main uses: comparative ('big' → 'bigger' = more big) and agent ('teach' → 'teacher' = a person who teaches).
