Illustrations that magically transform the number One into a Giraffe, Two into a pair of Ducks, Five into five colourful socks, and Six into half a dozen jumping yoyos, will being delight to children and double their fun while learning to count to 20. The technique of a flap hiding one of the objects creates the opportunity for children to play endless games with caring parents of "guess what is under the flap" and "let's count the pictures".
