How to Build Reading Comprehension (It Starts Before They Can Read)
A child can sound out every word on a page and still not understand it. Comprehension is a separate skill — and you can start building it at story time.
Reading has two big parts: decoding (turning letters into words) and comprehension (turning words into meaning). Fluent decoding is necessary but not sufficient — plenty of children read a sentence perfectly aloud and can't tell you what it meant. The good news is that comprehension can be nurtured long before a child reads independently, through the way you share stories together.
Background knowledge is the hidden ingredient
Comprehension depends heavily on what a child already knows. A story about a farm makes far more sense to a child who knows what a barn and a tractor are. Every story you share widens that base of knowledge, which then powers understanding of the next story — a compounding effect literacy researchers emphasise.
Ask the questions that build understanding
- Predict: 'what do you think will happen next?'
- Infer: 'why do you think she did that?' — inference is the heart of comprehension.
- Connect: 'has that ever happened to you?'
- Summarise: 'what happened in the story?' — retelling consolidates meaning.
- Clarify vocabulary as you go, so unknown words don't break the meaning.
These are the same interactive habits that define dialogic reading, and the research on that approach shows gains in exactly the language skills comprehension is built on. You're not testing your child — you're modelling the thinking that skilled readers do automatically.
Frequently asked questions
What's the difference between decoding and comprehension?
Decoding is turning printed letters into spoken words; comprehension is understanding what those words mean. A child can decode accurately and still not comprehend — the two skills develop somewhat separately and both need support.
Can I build comprehension before my child can read?
Yes. Shared reading — asking questions, discussing characters' motives, and building background knowledge — develops comprehension skills well before a child reads independently.
Why does background knowledge matter for comprehension?
Understanding a text depends on what you already know about its topic. Every story a child hears widens their knowledge base, which helps them understand future texts — a compounding advantage.

You don't need flashcards or apps to raise a reader. The research points to something simpler: read aloud, every day, and make it something your child looks forward to.
Everyday conversation is wonderful — but it recycles the same few hundred words. Books reach for rarer ones, and that's exactly where new vocabulary comes from.
Reading is one of the few activities that supports language, thinking and emotional development all at once — and the evidence for the language part is especially strong.
