Phonics breakdown
Phonics Rule: TR Blend
Sound“tr”·/tr/
T and R blend together — you hear both sounds! Like in 'tree' and 'try'.
The blend TR combines /t/ and /r/ spoken quickly together.
Examples
Phonics Rule: Open Syllable U — “oo” (Long U)
Sound“oo”·/uː/
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 (“yoo”) rule, but when the lone U follows L, R, S, or J it drops the Y-glide and says pure “oo” (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: TH Digraph (Unvoiced)
Sound“th”·/θ/
TH can make a soft sound “th”, like in 'think' and 'bath'. Just air, no buzz!
The unvoiced TH “th” is the quiet, breathy version. Your throat doesn't vibrate. Stick your tongue between your teeth and blow air.
Tip
Unvoiced TH is quiet — think with three teeth!
Examples
Phonics Rule: Suffix -FUL
Sound“ful”·/fəl/
Adding -FUL means 'full of', like 'helpful' (full of help) and 'beautiful'.
The suffix -ful means 'full of' or 'having the quality of'. Note: the suffix is spelled with one L (-ful), not two (-full).
Tip
FUL means full of — helpful is full of help!
