Good readers use three cueing systems while reading: syntactic (structure), graphophonic (visual), and semantic (meaning). Struggling readers tend to rely mostly on the visual cueing system.
To develop the systems your child is not using, you can provide the following prompts:
Did that make sense?
Look at the pictures.
What do you think it might be?
Can you re-read this?
Did that sound right?
