Parents ask me this more than almost anything else: should I be teaching sounds, or should I be teaching whole words? The honest answer is that this isn't really an either/or question — but the two methods do different jobs, and knowing which one to reach for saves a lot of frustration.
What phonics actually does
Phonics teaches your child that letters represent sounds, and that sounds blend together to make words. "C-A-T" becomes "cat" because your child has learned what each letter sounds like and how to string them together. This is what lets a child sound out a word they've never seen before — the single most useful skill for becoming an independent reader.
The tradeoff: English spelling is inconsistent. Phonics explains "cat" and "sit" beautifully. It struggles with "said," "the," and "once." No amount of sounding out gets a child to "said" through pure phonics.
What sight words actually do
Sight words are the common words — "the," "was," "said," "you" — that a child memorizes by sight rather than sounding out. These words show up constantly in early reading, and many don't follow regular phonics rules. Memorizing the 100 or so most common sight words gets a huge amount of everyday text within reach quickly.
The tradeoff: memorization doesn't transfer. Knowing "said" by sight doesn't help your child read "paid," even though they look similar. Sight words alone don't build the tool a child needs for unfamiliar words.
Why the fight between the two methods is mostly pointless
Nearly every strong early-reading approach actually uses both, just without labeling it. Your child needs phonics to decode new words, and a working set of memorized sight words to handle the common irregular ones without getting stuck every other sentence. Treating this as a philosophical choice mostly just adds stress that doesn't need to be there.
What this looks like at home, practically
- Sound out regular words together. When your child hits a word like "jump" or "frog," help them sound each letter and blend it, rather than just telling them the word.
- Just tell them the irregular ones. Don't make your child struggle to sound out "said" — that word doesn't play by the rules. Say it, move on, and it'll stick with repeated exposure.
- Read the same books repeatedly. Repetition is how sight words actually get memorized — not flashcard drilling, just genuine repeated exposure through books your child enjoys enough to return to.
- Don't quiz mid-story. Stopping every page to test recall turns reading into an exam. Save any check-ins for after the story, if at all.
When to worry, and when not to
It's completely normal for a five- or six-year-old to mix up similar-looking sight words, or to need several attempts at sounding out a longer word. That's the process working, not a sign of a problem. What's worth watching for is a child who seems to have no strategy at all — not sounding out, not guessing from pictures, not recognizing any repeated words — after months of regular reading time. That's a reasonable moment to loop in a teacher or tutor for a second opinion, not because anything's gone wrong, but because a specific technique gap is often quick to close with the right support.
