Consonant Blends
A consonant blend contains two consonant graphemes whose sounds work closely together while remaining individually heard. Unlike consonant digraphs (where two letters represent a single phoneme, like sh), blends contain two distinct phonemes.
Blends vs. Digraphs: The Core Distinction
In phonics instruction, keeping blends and digraphs distinct is vital for accurate reading and spelling:Digraphs (sh, ch, th, ck, wh) combine two letters to make one sound (Elkonin boxes: 1 box).Blends (st, bl, tr) combine two letters where both sounds are heard (Elkonin boxes: 2 boxes: [s] [t], [b] [l], [t] [r]).
Canonical Consonant Blends (ST, BL, TR)
Explore the foundational consonant blends in our systematic curriculum:
ST Blend (/s/ + /t/)
The letters s and t appear together at the beginning (stop, step) or end (best) of words. Both /s/ and /t/ are distinctly heard.
Hiss air through teeth for /s/, then instantly tap tongue to alveolar ridge for /t/.
BL Blend (/b/ + /l/)
The initial blend where voiced stop /b/ glides smoothly into liquid /l/ as in black, blob, blot, and blip.
Press lips together to release voiced /b/, then immediately place tongue tip behind upper front teeth for /l/.
TR Blend (/t/ + /r/)
The initial blend where unvoiced stop /t/ transitions into liquid /r/ as in trip, trap, trim, and trot.
Tap tongue tip against alveolar ridge for /t/, then smoothly curl tongue slightly back for liquid /r/.
