"The fourth of four levels of decodable books, providing the best start for children just starting to read. At every stage the words are within the reach of children as they use their letter sound knowledge and tricky words already taught.
Tricky words are shown at the back of each book. Light type is used as a guide for those few letters that should not be sounded out, such as the /b/ in lamb."
