This brilliant Wipe-Clean Activity is perfect for helping 4-5 year olds build key Maths skills - it''s an ideal way to introduce them to their first sums with addition and subtraction! Each book comes with a wipe-clean pen so children can practise again and again.This book is full of fun and colourful exercises on how to add numbers to create totals up to 10 and subtract numbers from 10 or less. It also introduces children to Number Bonds of 5 and 10, and we''ve added in fun puzzles to bring together what they''ve learned to start working out sums on their own. This book can be used in class or at home, and it''s great for helping pupils develop their pen control too!
