Phonics breakdown
Phonics Rule: Letter H
The letter H makes the /h/ sound, like in 'hat', 'hop', and 'hen'. It is a soft breath of air.
H is a voiceless glottal fricative — just a puff of air with no friction. It always appears before a vowel and is sometimes silent (as in 'hour' or 'honest').
Tip
H is a puff of air — breathe out and say /h/!
Examples
Phonics Rule: EA Vowel Team (Long E)
When E and A are together, they usually say long E, like in 'teach' and 'beach'.
The vowel team 'ea' most commonly makes the long E sound /iː/. However, it can also say short E (like 'bread') or long A (like 'great'). The long E pronunciation is by far the most common.
Tip
When two vowels go walking, the first one does the talking.
Examples
Phonics Rule: Letter 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: 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).
