Math Antics - The Number Line

To teach viewers about measuring time, how different units of time are related, and how to read a traditional clock.

Seconds, minutes, hours, and days.

A day is the amount of time it takes the Earth to rotate on its axis one time.

To plan daily activities, as a day is a long period.

There are 24 hours in a day.

There are 60 minutes in an hour.

There are 60 seconds in a minute.

'd' for days, 'h' for hours, 'min' for minutes, and 's' for seconds.

A sundial.

It uses three hands: the second hand, the minute hand, and the hour hand.

The minute hand moves one mark per full rotation of the second hand.

One hour has passed.

Because there are only 24 hours in a day, not 60.

The hour hand makes two full trips around the clock face, six hours each time, using 'a.m.' and 'p.m.' for distinction.

'a.m.' stands for ante meridiem ('before noon'), and 'p.m.' stands for post meridiem ('after noon').

By writing the hours first, then minutes, and then seconds, if necessary, all separated by colons.

A digital clock can label the 24 hours of the day directly as numbers, from 0 to 23.

You determine whether it’s before noon or after noon or look for clues that indicate the time of day.

They might provide clues, such as 'soon the sun will set,' to indicate whether the time is a.m. or p.m.

The way to get good at anything in math, including telling time, is to practice.
