Your child will help Dora and Diego find missing letters, solve puzzles and complete activities that will encourage development of essential reading and writing skills. They will learn spelling, opposites and categorization, as well as common words in categories such as toys, feelings, animals, actions and more. Children can fill in the blanks with the included erasable pen on the write-and-slide pages and slide the tab to check their answers, then complete the fun activities that will help advance their skills.
