Hours and days

Learning focus

Learn about the number of minutes in an hour and the number of hours in a day.

This lesson includes:

  • one learning summary
  • two interactive activities


In this lesson, you will learn how we measure time on a clock and estimate how long different events take.

First, look at the slideshow below to understand how we measure time using clocks. Try looking at a clock or watch in your home to help you to answer the questions.

Different types of clocks and units of time: seconds, minutes, hours, days, weeks, months, years

Time is a unit that can be measured. We use different instruments to measure time. We measure it in different units such as seconds, minutes, hours, days, weeks, months and years.

Just a minute

You can use words to help count a minute without using a stopwatch. You can say '1 elephant, 2 elephants, 3 elephants' and so on for each second until you get to 60 elephants for 1 minute.

Can you think of any other words that you could use to help you to count to a minute?

Now let's look at some more units of time on a clock in the next slideshow.

A clock labelled a quarter of an hour or 15 minutes, a clock labelled half an hour or 30 minutes and a clock labelled three quarters of an hour or 45 minutes.

How many minutes are there in a quarter of an hour? How many minutes are there in half an hour? How many minutes are there in three quarters of an hour?
