Read it yourself with Ladybird is one of Ladybird's best-selling reading series. For over thirty-five years it has helped young children who are learning to read develop and improve their reading skills.

Each Read it yourself book is very carefully written to include many key, high-frequency words that are vital for learning to read, as well as a limited number of story words that are introduced and practised throughout. Simple sentences and frequently repeated words help to build the confidence of beginner readers and the different levels of books support children all the way from very first reading practice through to independent, fluent reading.

There are more than one hundred titles in the Read it yourself series, ranging from classic fairy tales and traditional stories from around the world, to favourite children's brands such as Peppa Pig, Kung Fu Panda and Peter Rabbit. A range of specially written first reference titles complete the series, with information books about favourite subjects that even the most reluctant readers will enjoy.

Each book has been carefully checked by educational consultants and can be read independently at home or used in a guided reading session at school. Further content includes comprehension questions or puzzles, helpful notes for parents, carers and teachers, and book band information for use in schools.

Water is a Level 4 Read it yourself book, ideal for children who are ready to read about subjects in some detail with a much wider vocabulary. Lots of information, detailed illustrations and analysis of the subject, that appeals to children who are ready to read independently. Includes contents, index and a picture glossary.
