Each double-page spread provides a complete teaching unit of about one hour. The illustrations are in full colour and are always shown close to the relevant text. The reading age of the sentences and the number of words on a page have been carefully controlled. The sentence structure is simple, accessible and friendly, with clear personalised questions. The pages are carefully designed to show the pupils a very clear route through each spread. Every page has a 'Things to do' section of questions. These are useful for homework, or as extra work for faster students, or for work during staff absence.
