Gr 1-4--Employing bright photography depicting life-size representations, this informational picture book introduces young readers to the concepts of size, measurement, time, and scale. Everyday objects such as candy and colored pencils are used to help readers visualize the math. The text favors short sentences, while bold, primary colors are seen on the mostly two-page spreads. Doneiger uses a combination of science, math, and humor to explore an often disparate collection of topics. The photography incorporates numerical facts that could be a jumping-off point to studying and practicing math. An accompanying section, "Life-Size Facts for the Very Curious," provides more detailed information. VERDICT Libraries with elementary students hungry for fact-based reading or looking for real-life math connections could use this book as an introductory text.
