The book mirrors the content of 7/1 and 7/2 and provides extension material linked to these resources. It is particularly appropriate for developing and extending the requirements of the new National Framework for Teaching Maths. There is a strong focus on mental work and non-calculator questions. It also contains non-National Curriculum areas designed to provide stimulating and challenging activities. Look out for Escher and Limping Seagulls for example! It is written by best-selling and experienced authors.
