What's A Pair? What's A Dozen?

What's a Pair? What's a Dozen? The world is filled with numbers. From learning to count their fingers to learning to put on their shoes, children encounter mathematical concepts early in life. Steve Swinburne introduces children to number-related words in this bouncy, colorful photo-essay. From one to a dozen, lively photographs illustrate math words such as single, double, couple and prefixes such as uni-, bi-, and tri- ("A triangle is a shape with three sides and a tricycle is a bike with three wheels."). The second half of the book is presented as a guessing game in which children are asked to identify in photographs the math concepts they've been shown earlier in the book. Following Lots and Lots of Zebra Stripes and Guess Whose Shadow?, books that explored patterns and shadows, Steve Swineburne offers another "child-friendly" and entertaining look at an all-important concept.
