For an introduction to the concept of numbers, this combination of bone bare text and appealing pictures by the author's husband Aldren Watson nicely fills the bill. Playing in the snow Linda, just out of babyhood, asks the questions from what is one? to what is ten?- while her older brother Peter tells her what corresponds to the numbers- from a single pine tree to her ten fingers and toes. The familiarity here will cultivate the germ of knowledge.
