Book 9c provides the link with writing for the words used in Readers 9a and 9b. Once the book has been completed, the child can move on to book 10a.
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.
