Lee and Pat have a very good week, and a very busy week. Every day, they visit some new and interesting place to explore and learn about.This entertaining new series of simplified, illustrated readers has been developed specifically in order to enable young children to learn to read by themselves, with only minimal help from parents or teachers.All the details in the book are revealed in language (words and structure) that has been rigorously selected to be as simple and understandable as possible for young readers.For example, did you know that just 25 most commonly used words make up about one-third of all words written or spoken in English? The first 100 most frequently used words make up about one-half of all written and spoken English. By the end of the 12-book Word by Word series, children will have learned the 1,000 most frequently used words which comprise more than 95% of all written and spoken English.The content of all Word by Word readers is based on extensive, diligent research into the most frequently used English words and structures. The key words and structures are presented gradually and systematically throughout the series. For example, all new words and structures are repeated at least 15 times subsequent to their first appearance in the series. This, together with the phonic emphasis in each book, ensures effective and rapid learning as well as maximum retention and comprehension. It is this very systematic control of vocabulary and structure that makes Word by Word graded readers unique.All the books in the series have been extensively trialed and repeatedly improved over a period of many years and are now proven to be extremely effective in building functional literacy in children of many ages and nationalities, including the author's own children.The series consists of 12 books in 4 levels:, Level 1Book 1: Lee and PatBook 2: Lee and Pat like to playBook 3: Lee and Pat go with DaddyLevel 2Book 4: Lee and Pat go to schoolBook 5: Lee has a friendBook 6: Lee and Pat like animalsLevel 3Book 7: A very good weekBook 8: Let's go shoppingBook 9: Pat's birthdayLevel 4Book 10: All about animalsBook 11: Our worldBook 12: All about peopleBy the end of the series, the child will have learned to read and understand all of the most important English words and structures.
