It's three books in one!Here's a rhyming and counting book that's unique: it's a book within a book within a book!Follow the zany adventures of the numerals as you count from one to ten. Then start all over again with the second, smaller book, and then the third. A pocket on the inside back cover of each book holds the next, smaller size book.Just the right size for small hands to hold, this is the perfect gift -- sure to entertain young readers for hours!.
