Editorial Reviews

School Library Journal
Gr 2-4-This is a succinct, child-friendly history of how time came to be measured, from our early ancestors, who noted how the sun traveled across the sky, to the ancient Egyptians, who used "Shadow Stick clocks" to mark its path, through present-day quartz and atomic clocks. Wells discusses the Egyptians' lunar and solar calendars and the Roman calendar, and goes on to explain time zones, using meridian lines. Analogies such as "WITHOUT TIME PASSING BY, you couldn't play a computer game or eat a bowl of ice cream-" help children understand the concepts. The characters in the pen-and-acrylic illustrations look a bit like a cross between B.C. and Doonesbury comics; the hand-lettered text creates movement around the sometimes multiple images on a page, and the combination of art and words results in fun. A terrific teaching tool, enjoyable as a read-aloud or when read independently.-Wanda Meyers-Hines, Ridgecrest Elementary School, Huntsville, AL Copyright 2003 Cahners Business Information.
