Write and Wipe Practice: ABC 123 introduces children to the letters of the alphabet (capitals and lowercase) and for each letter, provides pictures and words for children to trace. It also introduces children to numbers, with objects to count and both the numeral and the number word to trace. Practice workbooks provide the essential repetition needed for the long-term retention of key learning points. It's the perfect hands-on format for children who are just learning about their letters and numbers and want to get a head start on their handwriting. With convenient, on-the-go spiral-bound wipe-clean pages and an embedded wipe-clean pen, kids can practice their ABCs and 123s anywhere, anytime! 3+ years.
