Traditional clocks that look like the ones here are called analogue clocks. These are the clocks we use first when we are learning to tell the time. They come in all shapes and sizes.
There are two long pointers on clocks. They are called hands. The big hand, shown here, is also called the minute hand. Each number the big hand passes is the same as five minutes in time. Each hour is sixty minutes long. The minute hand tells you how many minutes have passed in each hour. Click the red square for more information five minutes past ten minutes past fifteen minutes past twenty minutes past twenty five minutes past thirty minutes past thirty five minutes past forty minutes past forty five minutes past fifty minutes past fifty five minutes past sixty minutes past
This clock says 6 oclock. The little hand is pointing to the 6. The little hand is also called the hour hand. It moves more slowly than the minute hand. Click the red square move the clock on by sixty minutes. The minute hand has moved all the way around the clock but the hour hand has only moved a short distance to the next number. The minute hand moves more quickly than the hour hand.
It takes the big or minute hand 60 minutes to go all the way around the clock. There are 60 minutes in 1 hour. There are 60 seconds in each minute! It takes the little or hour hand 24 hours to go all the way around the clock. There are 24 hours in 1 day.
When the big or minute has moved to the number 3 it is called quarter past. When the big or minute has moved to the number 6 it is called half past. When the big or minute has moved to the number 9 it is called quarter to. When the big or minute has moved to the number 12 it is called oclock.
When the minute hand has moved to half past each hour we stop saying the word past and start using the word to. So… 35 minutes past is called 25 minutes to 40 minutes past is called 20 minutes to 45 minutes past is called quarter to 50 minutes past is called 10 minutes to 55 minutes past is called 5 minutes to
Click on the red square five minutes past ten minutes past quarter past twenty minutes past twenty five minutes past half past twenty five minutes to twenty minutes to quarter to ten minutes to five minutes to oclock
