In Foundation Stage and Key Stage 1, the children are learning phonics regularly to help them become fluent readers. It can be a tricky task to read all those different sounds and still understand the story. Children may need to re-read a story a number of times to help them with their comprehension. The BEST way of children showing their understanding of a story is to read it with expression.
At home, some things to help with their fluency:
If they get stuck on an unfamiliar word, encourage them to segment the word, look for sounds they recognise and blend those sounds.
Ensure they take notice of punctuation, stopping at full stops and change their tone for questions and exclamation marks.
Once they're confident with reading it correctly, then have a go at re-telling with great expression.
