Use this website https://www.oxfordowl.co.uk/for-home/find-a-book/library-page/ to read some reading books.
Go to Levels then Book Bands and you can select the colour reading book your child is working on. In EYFS, we start on pink then move on to red and yellow.
Remember to talk about the pictures and story/content first, as this will help with unfamiliar words – for example, we can’t sound out hippopotamus but if they use the picture and initial sound h you can work it out. Don’t forget to use your sounds and tricky words!
