This "Green Storybook" will help children to learn to read using Ruth Miskin"s highly effective Superphonics method. There are four levels in the "Storybook" series - Blue (the easiest), Green, Purple and Turquoise (the hardest). Each level is linked to one of the core "Superphonics" books. "Green Storybooks" practise the sounds taught in "Superphonics Book 3". All the Storybooks are fun to read and beautifully designed and illustrated in colour.
