Why Phonics Matters: What It Changes in How a Child Reads
by I Can Read Singapore on 18 Aug 2026
There are two ways a young child can identify a written word. They can recognise it because they have seen it before, or they can work it out using the sounds represented by the letters. Both look like reading at age five. Only one still works at ten.
The difference, in one example
Put the word "stagnant" in front of two seven-year-olds who have never seen it.
The first has learned to read by recognising familiar words. This one is not familiar, so there is nothing to recognise. They guess from the shape, or from the picture, or they stop.
The second has learned to decode. They break it into parts — stag / nant — sound it out, and produce something close enough to the word that if they have heard it before, they will recognise it. If they have not, they can still read it aloud and carry on.
Neither child is brighter. They were taught differently.
What phonics actually gives a child
A method for words they haven’t seen before. This is the whole point. English has far more words than any child can be individually taught, and the number of unfamiliar words a child meets rises sharply through primary school. Decoding is a tool that scales, memory is not.
Spelling that follows from reading. A child who can hear the sounds in a word and knows which letters make them has a system for spelling, rather than a list to memorise. It is the same knowledge running in the other direction.
Independence. A child who can attempt any word does not need an adult beside them. That changes how much they read, which changes everything downstream.
A way through for children learning English alongside another language. In Singapore many children hear more than one language at home. Phonics gives them the English sound-to-spelling system explicitly, rather than leaving them to infer it from exposure — which is slower and less reliable when exposure is divided.
Why the difference shows up late
This is the part that catches families out.
Word memorisation works well for a while. In K1 and K2 the vocabulary is small and repetitive, and a child who memorises can look ahead of a child who is still sounding words out slowly. Some parents conclude the memorising child is the stronger reader.
Then the texts get longer. The words get less common. The proportion of any page that a child has seen before drops, and the memorising strategy quietly stops covering enough of it.
By upper primary the effect is visible, and it usually presents as a comprehension problem — the child reads the passage and cannot answer the questions. Often it is not comprehension at all. It is that so much effort is going into working out the words that there is nothing left over for meaning.
What phonics does not do
Being straight about this matters, because phonics is sometimes sold as the whole answer.
Phonics is a necessary starting point, but it is not the whole picture.
- Vocabulary. A child can decode "stagnant" perfectly and have no idea what it means.
- Fluency. Reading accurately but slowly still leaves little attention for meaning.
- Comprehension. Understanding a text needs background knowledge, inference and vocabulary.
This is why a phonics programme that ends when phonics ends leaves a job half done. Decoding is the foundation. Fluency and comprehension are the building.
How we approach it
Our programme focuses on teaching children to decode words rather than memorise them, using a system developed by educational psychologists. Before starting, every child completes an English Assessment, ensuring placement is based on their literacy ability rather than age alone.
Our Reading Foundations builds the essential pre-reading skills children need before they begin reading independently. Champion Readers builds on these foundations, developing independent reading, spelling, comprehension and early writing skills. Headstart to Primary 1 prepares K2 children for the transition to Primary School English, while our Primary English Programme continues their learning journey from Primary 1 to Primary 6, strengthening their English skills as they progress through primary school. Together, these programmes provide a progressive learning pathway that supports children from their earliest literacy foundations through to primary school, building their skills at every stage.
Frequently asked questions
Why is phonics important?
It gives a child a method for reading words they may not have seen before. No child can be taught every word individually. Decoding is the only approach that keeps working as texts get harder.
What are the benefits of phonics for children?
There are four main benefits: a method for reading words they may not have seen before; a system for spelling, rather than a list of words to memorise; greater independence, as children who can attempt unfamiliar words can read without constant adult support; and, for children who speak more than one language at home, a clear route into English sounds and their written forms.
Is phonics better than learning whole words?
For the majority of English words, yes — they follow patterns a child can decode. A small number of common words genuinely do have to be learned by sight, but that list should stay short.
My child reads well without phonics. Is that a problem?
Not necessarily, but it is worth checking. Ask them to read an unfamiliar longer word. A child who attempts it is decoding. A child who guesses or stops may be relying on memory, which becomes limiting later.
Does phonics help with spelling?
Yes. Hearing the sounds in a word and knowing which letters represent them is the same knowledge used for reading, applied in reverse.
Is phonics enough on its own?
No. Phonics teaches children to associate a letter with a specific sound. However, vocabulary, fluency and comprehension are separate skills that are also very important.
Does phonics work for children who speak another language at home?
Yes. It can be particularly useful because it gives children structured practice with English sounds and their written forms, helping them become increasingly familiar with the relationship between the two over time.
