Clocks tell time and help people know when to wake up, go to sleep, attend meetings or games. They were invented in 1797 by Eli Terry and have changed over time, originally using Roman numerals instead of numbers. While clocks are useful for keeping on schedule, they can be inaccurate or take up space, though watches serve as a substitute. Clocks can cost anywhere from $1 to $500 and are sold at stores like Best Buy, Walmart, Target and more.

• Clocks help us because clocks tell time. We
just need to look on the clock and then the
clock tells us what time it is. Whenever we are
not sure what time it is, we can go to sleep
and use the clock to set the time. Then we
know if it is time to sleep, go to a soccer
game, or wake up. Clocks are very important
