Phonics breakdown
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: OI Diphthong
OI makes the /ɔɪ/ sound in the middle of a word, like in 'oil' and 'coin'.
A diphthong is a vowel sound that glides from one sound to another. OI glides from /ɔ/ to /ɪ/. Use OI in the middle of a word and OY at the end.
Tip
OI in the middle — coin and point!
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).
