Opis
In this book, readers learn what the clock measures and why knowing how to tell time--in seconds, minutes, and hours--is important. They learn the history of the clocks, including sundials and hourglasses. They also learn how to read analog and digital clocks to tell time. Sidebars instruct math by showing readers how to add and subtract hours.
