Book excerpt: Friends Charlie and Marv are trying to invent a new invention for a school project - but it's harder than it looks! Maybe Charlie's little sister Lola can come up with some ideas... Read it yourself with Ladybird is one of Ladybird's best-selling 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 four different levels of books support children all the way from very first reading practice through to independent, fluent reading. 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 puzzles, helpful notes for parents, carers and teachers, and book band information for use in schools. Charlie and Lola: I Am Inventing an Invention is a Level 4 Read it yourself title, ideal for children who are ready to read longer stories with a wider vocabulary and are keen to read independently.
