Book Description: Numbers & nonsense have never been so much fun as they are in this brilliant moving-parts book by Caldecott Medalist Paul O. Zelinsky. A young boy sets out on a walk -- pull the tabs & tiny old men from One to Ten act out the familiar refrain of the traditional counting song on & all around him. As dogs chase bones & old men roll home, paper doesn't simply pop up -- it seems virtually animated. The spectacular numerical extravaganza of motion at the end gives a whole new meaning to the idea of playing knick-knack. The words & music to the song are on the back cover. Paper engineering by Andrew Baron.
