The first Key Words with Peter and Jane book, from Ladybird. Key Words with Peter and Jane uses the most frequently met words in the English language as a starting point for learning to read successfully and confidently. The Key Words reading scheme is scientifically researched and world renowned. Book 1b follows on from 1a and introduces 16 new words, including 'toys', 'has', 'trees' and 'ball'. Once this book has been completed, the child moves on to book 3b. The Key Words with Peter and Jane books work because each of the key words is introduced gradually and repeated frequently. This builds confidence in children when they recognise these key words on sight (also known as the 'look and say' method of learning). Examples of key words are: the, one, two, he. There are 12 levels, each with 3 books: a, b, and c. Series a: gradually introduces new words. Series b: provides further practise of words featured in the 'a' series. Series c: links reading with writing and phonics. All the words that have been introduced in each 'a' and 'b' book are also reinforced in the 'c' books The Ladybird Key Words with Peter and Jane series: Play With Us; Reading with Sounds; Boys and Girls; Read and Write; Fun and Games; Mountain Adventure; The Carnival; Books are Exciting; Happy Holiday; Jump from the Sky; I Like to Write; We like to Help; The Big House; The Mystery on the Island; Adventure at the Castle; Sunny Days; Out in the Sun; More Sounds to Say; Learning is Fun; Say the Sound; Enjoying Reading; The Open Door to Reading; Easy to Sound; Let me Write; Adventure on the Island; Boxset; Fun with Sounds; Games We Like; Have a Go; Fun at the Farm; Where we Go; The Holiday Camp Mystery; Our Friends; We have Fun; Things We Like; Things We Do; Look at This; and Flash Cards.
