Build your child's vocabulary at home
Vocabulary is the single best predictor of reading comprehension after 3rd grade. Kids with bigger word banks understand more of what they read — and the gap compounds every year. The good news: you build vocabulary through conversation, not flashcards.
Three tiers of words
Researcher Isabel Beck divides words into three tiers. Tier 1 = everyday (dog, run). Tier 2 = rich, useful across topics (curious, enormous, vanish). Tier 3 = specialized (photosynthesis). The biggest payoff is Tier 2. Sprinkle 1–2 Tier 2 words into your child's day, every day.
Why conversation beats lists
Kids learn words best in real context — used by someone they care about, in a moment that matters. A word heard at dinner ('this soup is delicious — that means really, really good') sticks far better than the same word on a worksheet.
Read above their reading level — aloud
Picture books, chapter books, and even short news articles read aloud expose kids to words they couldn't yet read on their own. This is how vocabulary outpaces decoding.
Try these this week
- 1
Word of the day
Pick one Tier 2 word at breakfast (eg. 'reluctant'). Use it three times today. Bonus points if your child catches you.
- 2
Synonym swap
When your child says 'big,' offer 'enormous.' When they say 'sad,' offer 'miserable.' Don't correct — just upgrade.
- 3
Read-aloud one level up
Read books one level above what your child can decode. Stop on 1–2 words per page to define in kid language: 'gigantic — that's another way to say really, really big.'
- 4
Cook a recipe together
Recipes are dense with verbs (whisk, fold, simmer) and nouns (zest, peel, cube). Narrate as you go.
- 5
Movie debriefs
After a show: 'What was the character's problem? How would you describe how she felt?' Push for vivid words.
- 6
Wonder walks
Walk the block. Name what you see in precise words: not 'tree,' but 'palm tree,' 'maple,' 'sapling.' Specificity grows vocabulary.
What to watch for
- Vague language for everything ('thing,' 'stuff,' 'good') past 3rd grade.
- Saying 'I don't know what that means' on common words for their age.
- Comprehension drops sharply when text is on an unfamiliar topic.

- Is reading aloud enough to build vocabulary?
- It's the single best thing you can do — and it's even better when you stop to define one or two words per page in kid-friendly language. Don't quiz; just plant.
- Are vocabulary apps helpful?
- Some, in moderation. Words stick when kids hear them in real conversation more than when they tap them on a screen. Apps are a supplement, not the engine.
- My child has a big spoken vocabulary but struggles to read. Why?
- Spoken vocabulary helps comprehension, but reading still requires decoding. If decoding is shaky, the vocabulary can't show up on the page. See our phonics guide.
