Fascinating Fact:

Sixty minutes make one hour. Many cartoons are half an hour which is 30 minutes.

In KS1 Maths, children learn the units of time and when to use them. Short actions like a blink take seconds, brushing teeth takes minutes, and a school morning takes hours.

  • Second: A very short unit of time; 60 seconds make a minute.
  • Minute: A unit of time; 60 minutes make an hour.
  • Hour: A longer unit of time, used for lessons or journeys.

Practise ordering and comparing first: try the Numeracy Game before you start the quiz.

What is the difference between hours, minutes and seconds?

Seconds are very short, minutes are longer, and hours are longest. There are 60 seconds in a minute and 60 minutes in an hour.

How do I choose the right unit for an activity?

Think about how long it feels: clapping once takes seconds, eating breakfast takes minutes, and going to school takes hours.

How many seconds are there in an hour?

There are 3,600 seconds in an hour, because 60 seconds make a minute and 60 minutes make an hour (60 × 60 = 3,600).
