Superphonics - the simplest, fastest way to teach your child to read. A superb series of graded readers using the phomic approach. There are four levels - Blue (the easiest), Green, Purple and Turquoise (the hardest). Each level is linked to one of the core Superphonics books. Purple Storybooks practise the sounds taught in Superphonics Book 4. All the Story books are fun to read and beautifully designed and illustrated in colour. Jack and the Beanstalk focuses on the following sounds: 'ee' as in 'tree', 'e-e' as in 'here', 'ea' as in 'bean' and 'y' as in 'hungry'.
