In book 2a, Peter and Jane are having fun at the beach in 27 new words including ‘look’, ‘to’, ‘go’ and ‘yes’. Once this book has been completed, the child moves on to book 2b.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 recognize these key words on sight (also known as the ‘look and say’ method of learning). Examples of key words are: the, one, two, he.
