“Knowing the time helps you get to school without being late. Knowing the temperature helps you decide what to wear.”
By examining two measurements that affect children daily, this book first makes it clear that both clocks and thermometers are devices to measure units. Then, each system of measurement is explained with appealing photos, simple text, and concrete examples: “In a second you can snap your fingers once.”
Includes brief time and temperature tables. Paperback, 17 pages. Ages 6 and up.
