Hi SJ, I wrote something on this topic previously, so will copy and paste some ideas below:

Reading is an important skill for key stage 1 learners to develop.

It helps them to improve their literacy, expand their vocabulary and increase their knowledge of the world around them.

Reading can also be a great entertainment source and help children develop empathy, as they learn about different characters and situations.

Reading can also help children to develop critical thinking skills, as they learn how to analyze what they have read.

Finally, reading can help children improve their concentration levels and focus on tasks for longer.
