Let's Do Addition and Subtraction is a brand new series of six titles in the popular 'Let's Do' range. Each book addresses the new National Curriculum maths specifications and contains a rich variety of activity pages and progress tests, with over 400 questions in total. Topics include column addition and subtraction by decomposition and practice of basic number bonds. Designed to be used at home with parental support, each book includes fun tips and clues, as well as extra challenges in Brodie's Brain Boosters. Building up speed and confidence is key, and so these books feature progressively more difficult activities with a progress test at the end of each section. There is a clear answer section for reference by parents and children, together with over 100 bright, colourful reward stickers.\
