The Oxford Reading Tree Green Sparks series explains and illustrates the 17 UN Sustainable Development Goals in an age-appropriate way. The series supports development of all reading skills by combining phonic progression with essential vocabulary, as well as extending the reader's comprehension of the issues around sustainability in global and local contexts. This will boost general knowledge and subject-specific vocabulary, as well as promote learner engagement and student wellbeing. The 42 levelled fiction and non-fiction books from Oxford Reading Levels 1 to 6 are linked to subjects in the wider curriculum, as well as to international curricula, such as the Oxford International Curriculum and the IB's Primary Years Programme. The Teacher Handbook includes cross-curricular activities designed to support children's understanding of the SDGs. Selected titles from this series can be accessed through the Oxford Owl eBook Library subscription. Free Teaching Notes are also available on Oxford Owl. The Oxford Reading Tree Green Sparks series will inspire young readers to become the problem-solving global citizens of tomorrow.
