Parents are usually told that sight words and phonics are rival methods and that they have to pick one. They are not rivals. They cover different words, and a child needs both — the argument is about proportion, not about whether one of them is allowed.

What each one actually is

Phonics teaches the sounds letters make, and how to blend them. c-a-t becomes cat. It is a rule the child can apply to a word they have never seen, which is why it scales: learn the rules and you can read most of the language.

Sight words are memorised whole, as shapes. No blending, no rules. Said, come, one, who. The child recognises the word the way they recognise a face.

Why both are unavoidable

English spelling is regular enough for phonics to be the main method and irregular enough that a child who only uses it gets stuck within one sentence.

Try sounding these out: said should rhyme with paid. Come should rhyme with home. One should start with an o sound. Was should rhyme with gas. Who should rhyme with how. A child who applies the rules correctly to those five words gets all five wrong — and those five are among the most common words in the language.

So: phonics for the majority of words, sight recognition for the small set of high-frequency irregulars. Roughly the top 100 words account for about half of everything a beginner reads, and a large slice of those top 100 are irregular. Memorising that small set buys a disproportionate amount of reading.

The Dolch lists, and where they came from

Edward Dolch compiled his lists in the 1930s by counting the words that appeared most often in children’s books. There are five lists — pre-primer, primer, first, second, third grade — plus 95 nouns. The first two are the ones that matter before age six:

• Pre-primer, 40 words: the words a child meets before they can decode anything at all. a, and, away, big, blue, can, come… Pre-K Sight Words Tracing covers this list.
• Primer, 52 words: the list that follows. Longer, and full of the rule-breakers. all, am, are, at, ate, be, black… Kindergarten Sight Words Tracing covers this one.

The lists are ninety years old and still in use, for the boring reason that the commonest words in English have barely changed.

Which words to memorise and which to sound out

The honest answer is that many words on the Dolch lists are perfectly decodable — can, big, run, up, and, at. Those do not need memorising, and treating them as sight words teaches a child to guess when they could have worked it out.

A practical division:

• Sound it out if every letter says its ordinary sound: cat, big, run, stop, and.
• Memorise it only if a correct application of the rules produces the wrong word: said, come, one, who, was, of, are, they, there, what.
• Part-decode the rest. Have is regular except for its ending. Teach the regular part and flag the exception; that is more useful than presenting the whole word as a mystery.

How to practise each one

Phonics practice is out loud. Word families do the heavy lifting because the pattern is visible: cat, hat, bat, mat — only the first sound changes. Read the four aloud before writing any of them. CVC Words Tracing puts one family on each page for that reason.

Sight word practice is look, cover, write. Read the word, cover it, say it, then write it. Covering is the whole exercise — a child can trace where perfectly six times without once looking at the whole word, and learn nothing.

Four sight words a session is enough. A page of ten gets abandoned halfway and the last six get traced without being read.

Run them at the same time

The common mistake is sequencing: finish phonics, then start sight words. Do both in the same week. A child reading a simple book needs the, said and come on the very first page, whatever stage their phonics has reached — withholding them means withholding books.

What to worry about

One thing: guessing from the first letter. A child who says “horse” for house and “there” for they is pattern-matching on the opening letters rather than reading. It is the failure mode of an over-reliance on whole-word recognition, and the fix is phonics — cover all but the first sound, uncover the rest, blend.
