Early Maths fun for 3-5 year olds, wipe-clean reusable addition book. The beginners wipe-clean workbook provides a fun way to introduce maths. The pages begin with smaller numbers and build up to large ones and includes the basic sums from 0+1 to 10+10 and represent the numbers as objects the child can relate to. Answers can be written in crayon, felt tip or washable marker pens and then wiped clean so the pages can be used again.
