This brilliant Wipe-Clean Activity Book is perfect for helping 3-5 year olds build key Maths skills - it''s an ideal way to introduce them to counting up to 20! Each book comes with a wipe-clean pen so children can practise again and again. It''s full of bright and colourful exercises, 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!
