The clock face: Many clocks have a number by each mark to make it easier to tell the time. These are the hours. The shorter hand points to the hour.It is called the hour hand. Notice that the number 12 is at the top and the numbers 1 to 11 go around in the direction shown by the arrow. (Fun fact: this direction is called clockwise.)

An hour is made up of 60 minutes. The marks in the picture above show each minute in the hour. Try to count each of the marks and see if you get to 60. As you count, notice that every 5 marks are exactly the same as the red hour marks. The hour marks are bigger, but they are used to count the minutes as well as the hours. The longer hand points to the minutes. It is called the minute hand.
