How to teach blending, and what to do when your child is stuck

01

What is blending in phonics?

Blending is how a child reads a word they have never seen before. They look at the letters, say the sound for each one, then push the sounds together until they hear a word. s, u, n becomes “sun”. That moment, when separate sounds turn into something that means something, is the heart of early reading.

It sounds simple to a grown-up, because we blend without noticing. For a four-year-old it is a real leap. They have to hold three sounds in their head, in the right order, and then hear that together they make a word they already know from talking.

What your child needs before blending

Your child doesn’t need to know every letter first. In most schools, blending starts after the first handful of sounds, often s, a, t, p, i and n, because those already make lots of short words: sat, pin, tap, pan, sip. What helps most is saying each sound cleanly. A short, pure “sss” blends far more easily than “suh”. If you would like to hear the difference, our guide to pure sounds has every sound recorded, and a blend lab to compare the two.

Blending also has a twin, segmenting, which is the same skill in reverse and is what your child uses to spell. We come to that in chapter 5. First, the good news: the very first steps of blending need no letters at all.

What is oral blending? Start with your voice, not letters

Oral blending means blending by ear. You say the sounds of a word, your child listens and says the whole word back. There is nothing to read, so all of their attention goes on the listening. Many children can blend aloud a while before they can blend from print, and the practice carries straight across when letters arrive.

You can do it anywhere: in the bath, at the table, on the walk to school. Keep the words short and familiar, and keep it light. If your child doesn’t get one, say the word for them happily and try another. This stage is about tuning the ear, not testing it.

Notice that “head” has four letters but only three sounds, h-e-d. In oral blending that doesn’t matter at all, which is one reason it makes such a gentle start.

03

What are sound buttons in phonics?

Once letters come in, many classrooms use sound buttons. Under each sound in a word sits a little mark: a dot under a sound written with one letter, and a short line, or dash, under a sound written with two or three letters. Your child presses each one with a finger as they say its sound, then swipes along underneath to blend the word.

The marks do two jobs. They slow your child down, so every sound gets said in order. And they show at a glance which letters belong together. In “ship” there are four letters but only three buttons, because s and h team up to make one sound, “sh”. In “night”, i, g and h share a single dash.

Those letter teams are called digraphs (two letters, one sound) and trigraphs (three letters, one sound). Spotting them is the next big step after simple words like “sun”. Our guide to digraphs and trigraphs walks through them one by one.

You don’t need special materials. Write a word on paper or a whiteboard and draw the dots and dashes yourself. Sometimes children like to draw them, which is good practice at spotting the teams.

How to teach blending: say the sounds, then say them faster

The simplest way to teach blending is the one you can hear in the slider. Say the sounds with a gap between them. Then say them again with a smaller gap. Then again, closer still, until there is no gap at all and the word pops out. Each pass, your child’s ear has less work to do to hear the word.

1. Point to each letter and say its sound: c… a… t.
2. Go back to the start and say them a little faster: c-a-t.
3. Faster again, pushing them together: “cat”.
4. Ask: “What word is that?” and let your child say it.

Keep the stretchy sounds going

Some sounds can be held for as long as you have breath: m, s, f, n, l, and every vowel. Use that. Instead of three separate sounds, stretch each one into the next without stopping: “mmmaaap”. This is sometimes called continuous blending, and many children find it easier, because the sounds never fully come apart in the first place. Words that start with a stretchy sound, like “sun”, “map” and “fan”, make a kind first step.

Short, bouncy sounds like t, p and d can’t be stretched. Say them crisply and move straight on, without an “uh” on the end.

05

Blending and segmenting: what is segmenting in phonics?

Segmenting is blending backwards. Instead of pushing sounds together to read a word, your child starts with a whole word and pulls it apart into its sounds, so they can write a letter or two for each one. Blending is for reading; segmenting is for spelling. Practising one tends to help the other.

The usual way to do it is to say the word, then say it slowly, then count the sounds on your fingers, one finger for each sound. “Bed. b… e… d. Three sounds.” Then your child writes one sound at a time, saying it as they go.

Counting on fingers is especially useful for words like “ship”. It has four letters, but your child only needs three fingers, because sh is one sound. That is exactly what sound buttons show when reading, turned around for writing.

Early spellings will often be phonetically right but not the usual spelling, like “bloo” for “blue”. That is a good sign: your child has heard every sound. The standard spellings come with time.

My child can’t blend sounds yet: what to do when they’re stuck

It is very common for a child to know their sounds well and still not be able to blend them. Knowing sounds and blending them are separate skills, and blending takes some children weeks or months longer than others. That is not a sign anything is wrong. For many children it seems to click quite suddenly: one day the sounds are just sounds, and the next they hear the word come out.

When your child is stuck, try not to jump in with the answer. Point to the word, ask for the sounds, and blend them together with your child. If there is a picture, look at it afterwards to check, not before to guess. Guessing from the picture or the first letter can feel like reading, but it skips the very skill that will let your child read words with no picture at all.

Little and often beats long and hard

A few minutes a day, every day, does more than one long session at the weekend. Stop while it is still going well. Go back to oral blending if letters feel like too much, and use words with only the sounds your child already knows. In Reception phonics, that means short words built from the first sets of sounds.

Some common words, like “the” and “said”, can’t be blended in the usual way yet. Those are tricky words, learnt by heart. And if blending is still hard by the end of Year 1, that is worth a word with the class teacher, who will know how your child is getting on with the phonics screening check.

In the app, Reception starts with oral blending: your child hears a word sound by sound and taps its picture. Later Reception lessons move on to sounding out written words, using only the sounds taught so far.
