Being able to read words aloud and understanding them are different skills; your child may be "reading" but not "understanding." One of the strongest predictors of reading comprehension is vocabulary: if the child doesn't know most of the words in a text, understanding becomes hard. Expanding vocabulary and processing what's read through conversation noticeably strengthens comprehension.
Detailed Explanation
This is a well-known situation and reveals an important truth: sounding out words correctly (decoding) and understanding what you read are two separate skills. Your child may be "reading" the text, but meaning is a separate door.
The key to understanding: vocabulary
One of the strongest predictors of reading comprehension is vocabulary. As Reading Rockets notes, a reader cannot understand a text if they don't know the meaning of most of its words. Studies on second-language reading also show that vocabulary contributes significantly to comprehension, both directly and indirectly through decoding and listening comprehension (PLOS One, 2025). So if a child can read the words but doesn't know their meanings, understanding naturally becomes hard.
Strategies that strengthen comprehension
Comprehension develops not only through vocabulary but also through strategies like predicting, inferring meaning from context, and visualizing what's read. Talking with the child about the text ("what do you think happens next?", "what could this word mean?") makes comprehension active. Reading together and discussing what's read is one of the most effective methods at this age.
To support reading comprehension
- Expand vocabulary; briefly introduce unknown words before reading.
- Choose texts suited to the child's level; most words should be known.
- After reading, talk about the text: what happened, why, what's next?
- Encourage the habit of predicting and inferring meaning from context.
- Read together; taking turns supports fluency and comprehension together.
Points to keep in mind
Giving a child texts far above their level, whose words they mostly don't know, undermines comprehension and can create reluctance toward reading. Also, fluent reading (sounding out words quickly) doesn't by itself guarantee comprehension. The real goal is for the child to visualize what they read; that comes through the right level, vocabulary, and processing through conversation.
Expert Note — Andrea Massari Rosario
When a child "reads but doesn't understand," I first look at vocabulary, because that's often where the issue lies. Then I turn reading from a silent task into a discovery we talk through together. When a child can retell the text, they've truly understood it; being able to read aloud isn't enough on its own.
