One tiny word that causes big Comprehension problems
There’s one small word that regularly trips children up in comprehension.
It’s not a long, complicated word.
It’s why.
When we see why in a question, we know it means: give a reason.
But many children don’t actually answer the reason. They answer something else.
Evidence is not the same as explanation
Take a typical comprehension question:
Why does the character decide to leave?
A child might go back to the text and write:
The character leaves the house and slams the door.
That shows they can find evidence. But it doesn’t answer the question.
The question is not what happens.
The question is why it happens.
They need to explain the motivation. The cause. The reasoning behind the action.
This distinction matters not just for exams, but for life. Being able to explain why something happens is at the heart of critical thinking.
A simple way to make this click
One way to demonstrate this is to act it out.
Ask your child to give you a “why” question. For example:
“Why are you wearing a hat?”
Then respond with:
“I am wearing a hat.”
They will laugh immediately. They know that isn’t an answer.
The fact that you are wearing a cap is already obvious. The question asks for a reason.
That small moment of humour makes the point clearly: a why question requires explanation, not repetition.
Why children miss this
Under time pressure, children often focus on finding the right line in the text. They are trained to look for evidence.
That’s useful.
But they also need to interpret that evidence and explain it.
The difference between:
Copying a line
Explaining a motive
…can be the difference between partial marks and full marks.
Turning it into a habit
Encourage your child to pause whenever they see the word why and ask themselves:
Have I given a reason?
Have I explained the cause?
Or have I just repeated what happened?
That mental check builds stronger answers and sharper reasoning.
Just be warned - once you’ve trained them properly, the next time you say, “Do it because I said so,” and they reply, “That’s not a reason,” you’ll know the lesson has worked!
