Circles

David. A. Adler, illus. by Edward Miller. Holiday House, $17.95 (32p) ISBN 978-0-8234-3642-2

Frequent collaborators Adler and Miller follow their books on fractions, time zones, triangles, and other topics with a thorough look at all things circular. After a brief run-down of two- and three-dimensional shapes with round aspects (cylinders, cones, spirals, etc.), Adler dives into what makes a circle a circle, unloading a significant amount of vocabulary along the way, including words like symmetrical, diameter, sector, and chord, all clearly explained in direct writing, assisted by hands-on project ideas and Miller’s playful circle-based animal portraits. By the time children get to the closing line—“We live in a world of circles”—they’ll be convinced. Ages 6–10. (Aug.)
