The Clever Mini Board Books are more than just adorable, graspable books – they are also an engaging learning tool! The format includes activities – stacking, sorting, counting, matching, and identifying colors – that encourage interactive learning of basic concepts. The colorful 5-in-1 gift box features a magnetic closure and individual interior cells to keep the 15 mini books in place. The books’ durable board pages introduce children to numbers and counting in a funny and interactive way and present examples of adding and subtracting. Each mini book – shaped like a stacking block – has rounded corners, measures 1.5” x 1.5” x 1.5” and is created to withstand the wear and tear of a preschooler’s active lifestyle. The books are a perfect tool to help children develop hand-eye coordination, curiosity, and emotional intellect.
