This paper explores the ways in which dual language books are used in England to support bilingual pupils in school. While pupils in many schools speak a wide range of languages at home, these hardly feature in the curriculum. In the context of a project in which an education authority provided dual language books to primary schools, the paper describes how two women used Albanian/English story books to teach their six-year-old daughters to read in Albanian. The study reports on how the mothers and their children used both texts to transfer skills from one language to another, to negotiate meaning in both languages and to compare reading strategies. At the end of the school year the girls were reading in English with the best in their class, were developing fluency in Albanian and using it more in the home. Their mothers had become closely involved in their daughters' schooling and reported improvements in their own English literacy skills. The teacher's role was crucial: by providing support and resources to parents she enabled them to help their children become additive bilinguals in a situation in which they were beginning to lose the active use of their first language.
