Lines and Triangles and Squares, Oh My!

Zoe Burke, illus. by Carey Hall. PomegranateKids, $10.95 (24p) ISBN 978-0-7649-7864-7

A gray cat named Bluebell helps introduce children to triangles, squares, circles, and other shapes. Writing in rhyme, Burke demonstrates how straight lines can form triangles and squares, and how, when tilted or stretched, a square can become a diamond or rectangle. Hall’s crisp, pastel-colored artwork emphasizes geometry whenever possible, sneaking shapes into wallpaper patterns, blankets, and landscapes for readers to identify. Burke’s verse can be clunky (“What shape are the pillows of yellow/ where Bluebell naps? That sleepy fellow!”) but it largely makes clear what characteristics define each shape. Up to age 5. (Mar.)
