What to do with a box of old buttons may seem like a slight notion for a book (and it doesn't made much of a story), but this lightly fictionalized enumeration of the ways that buttons' variety can open windows on critical thinking should provide an inspiration to parents and teachers. The young narrator explains how Grandma's buttons can be sorted by shape, size, color, material, and the manner of their decoration; and how they come from different sources, like uniforms, and suggest imaginative play (jewels for ""kings and queens and movie stars""). Chamberlain's bold linoleum cuts, with gentle color added, portray the buttons is loving detail and give the book an appropriately old-fashioned flavor. A good idea, well carried out.
