Sight Words vs Phonics: What Order Should Kids Learn to Read?

If you’ve shopped for reading resources, you’ve probably seen two very different approaches: “learn to sound it out” (phonics) and “learn these words by sight” (sight words). It’s easy to wonder which one your child should do first, or whether they’re rivals at all. The short answer: they work together, and phonics leads. Here’s how to think about it.

The short answer

Teach phonics first. It gives your child a tool to read almost any word independently. Sight words then support that tool by making a handful of common, irregular words instant — so reading flows. Sight words don’t replace phonics; they fill a small gap it leaves.

What is phonics?

Phonics teaches the link between sounds and the letters that represent them. A child learns that s–a–t blends into “sat,” and can then use that same skill to decode thousands of words they’ve never seen before. It’s a strategy, not a list to memorise. If you’re new to it, our guide on what age to start phonics is a good starting point.

What are sight words?

Sight words are high-frequency words a child learns to recognise instantly, without sounding them out. They matter because a small number of words make up a huge share of everyday text — words like the, and, a, to and was appear on nearly every page.

There are really two kinds:

• Decodable high-frequency words — like and, in, can, up, at. These follow phonics rules, so your child can sound them out. They just appear so often that recognition becomes automatic with practice.
• Tricky (irregular) words — like the, said, was, you. Parts of these don’t follow the usual rules, so they genuinely need to be learned by sight.

The myth of “just memorise whole words”

An older approach asked children to memorise whole words by their shape. The trouble is it doesn’t scale — there are far too many words to memorise, and it gives a child no way to tackle an unfamiliar one. Decades of reading research point clearly toward phonics as the foundation, with sight recognition as a helpful add-on for the few words phonics can’t easily crack. So you’re not choosing one or the other; you’re choosing phonics first.

Which sight words actually need memorising?

Not as many as you’d think. Focus your memorising energy on the genuinely tricky words, where the usual sounds don’t quite work:

the, a, to, of, said, was, were, you, your, are, they, my, by, he, she, we, me, be, do, go, no, so, here, there, what, all, come, some, one, once

Even with these, point out the part that does follow the rules and the small part that’s tricky — children remember “heart words” better when they know exactly which bit to watch.

How phonics and sight words work together

In a real book, a fluent young reader is doing three things at once:

1. Decoding most words with phonics (this is the workhorse).
2. Instantly recognising common words they’ve met many times (smooths the flow).
3. Remembering the handful of tricky words that don’t play by the rules.

Phonics does the heavy lifting; sight recognition keeps reading from feeling slow and choppy.

A simple order to teach reading

1. Letter sounds — the building blocks (say “mmm,” not “em”).
2. Blend CVC words — cat, sun, pin. See our CVC words guide.
3. Digraphs and blends — two letters, one sound, like sh and ee. See what are digraphs.
4. Sprinkle in tricky sight words as they appear in the books you read together — a few at a time, in context.
5. Read, every single day. Real books are where all of this comes together.

How to teach tricky sight words

• Use the “heart word” trick. Sound out the regular part, then mark the tricky part with a little heart: your child learns exactly which letters to remember.
• Keep flashcards light and playful. Short, frequent bursts beat long drills. Turn it into a game — hide words around the room, or play snap.
• Meet them in real books. A word your child spots on the page, in a story they love, sticks far better than one on an isolated card.

The bottom line

It isn’t sight words versus phonics. Lead with phonics so your child can read independently, then layer in the small set of tricky sight words that keep reading smooth. Get the order right and the two reinforce each other beautifully.
