This brilliant Wipe-Clean Activity Book is perfect for helping pupils aged 3-5 build Maths key skills - it's an ideal way to introduce them to writing numbers up to 20! Each book comes with a wipe-clean pen so children can practise again and again. It's full of fun and colourful exercises on how to write numbers up to 20 by tracing and following arrows, and we've added in fun puzzles to bring together what they've learned to start writing numbers 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!
