Teaching blending and segmenting in the classroom

For pupils who need explicit support blending sounds for reading and segmenting words for spelling

Blending and segmenting are related but serve different purposes.

Blending combines the sounds represented by letters to read a word.
Segmenting separates a spoken word into sounds so that it can be spelt.

A pupil may recognise individual sound-letter patterns but struggle to combine them in reading or separate them in writing. Use the terminology and sound pronunciation from the school's phonics programme so the pupil meets one consistent routine.

Blending for reading

Choose a few words containing patterns that have already been taught, ideally from current classroom reading.

Show the complete word.
Ask the pupil to identify the sound represented by each letter or letter group.
Move through the sounds without leaving long gaps.
Blend them into the whole word.
Read the word again in its sentence.

For stamp, say each sound in order (/s/ /t/ /a/ /m/ /p/), blend them without gaps into the whole word, then return to the sentence so that decoding reconnects with meaning.

Segmenting for spelling

Say the complete word clearly and ask the pupil to repeat it.
Stretch or say it slowly enough to identify the separate sounds.
Record the letter or letter group representing each sound.
Read the completed word.
Use it in the sentence.

For float, help the pupil hear the four sounds (/f/ /l/ /oa/ /t/) and choose a spelling for each. If they write flote, point to the /oa/ sound and remind them which spelling of it this word uses.

Correct the point of difficulty

If a sound-letter pattern is misread, point to the relevant letters, remind the pupil of the sound and ask them to blend the complete word again. For spelling, identify the sound or pattern that needs changing, then ask the pupil to write and read the word again.

The pupil should finish the process successfully rather than only watch an adult provide the answer.

Adjust the support

Some pupils benefit from five to ten minutes of closely supported practice during daily literacy teaching; others need only a few planned opportunities each week. A brisk two-minute oral warm-up works with either, for example at the start of a phonics or literacy lesson. Say the sounds (/d/ /i/ /g/) for the pupil to blend, then say a word (jump) for them to segment, and mix the two once both are secure.

Closer support may include:

teacher modelling before an attempt;
immediate, brief correction;
a small, carefully selected word set;
practice in both reading and spelling; and
repeated use of the same routine.

A physical cue can help a pupil keep the sounds in order. In tap and sweep, the pupil taps one finger for each sound as they say it, with one tap for a digraph such as sh, then sweeps a thumb across the fingers while saying the whole word. Older pupils can tap up the forearm instead. If the school's phonics programme has its own gesture, use that.

Reduce prompts as accuracy improves. Allow time for the pupil to identify the sounds and choose the process independently.

Check transfer

Move beyond isolated words once the routine is accurate. Ask the pupil to read the word in a sentence, use it in writing and recognise the same pattern in another word. This shows whether the learning is transferring into classroom work.

Brief classroom practice is not a substitute for structured intervention where decoding difficulties are substantial or persistent. Discuss further assessment with the literacy lead or SENCo when a pupil makes limited progress despite frequent, well-matched practice, cannot apply secure patterns to unfamiliar words or needs so much support that ordinary classroom reading remains inaccessible.
