First: children should touch the clock, pull the hour hand and minute hand, and have a simple understanding.

It's boring to know the time only by comparing with the plan. Children must have a good contact and observation of the real thing, distinguish the hour hand, the minute hand and the second hand, and learn some little knowledge of clocks.

① There are 12 squares on the clock face, 60 squares, and one square has 5 squares. The hour hand walks a big square, which is 1, the minute hand walks a big square, which is 5 minutes, and the second hand walks a big square, which is 5 seconds. When the two squares of the hour hand are 2, the two squares of the minute hand are 10 and the two squares of the second hand are 10. ...

(2) When the hour hand moves a big square, the minute hand just moves 60 small squares, which is 60 points, 1 =60 points.

(3) On the clock face, the hour hand is 4 hours from 12 to 4 o'clock; From 1 to 5, it is 4 hours; When it is from 2 to 12, it is 10, and it is 10 hour. But remember that the minute hand and the second hand are different.

Second: be sure to draw more clocks manually, and know the time on the clock while drawing. There are three kinds of time to know.

① on the hour

The minute hand points to 12, and the hour hand points to what time.

② The minute hand points to a large number of squares.

What is the hour hand, such as 3 or 4, and the minute hand points to 6, which is 3:30.

(3) The minute hand does not point to the large grid number.

The hour hand is between 1 and 2, and the minute hand is between 3 and 4, which is the square of 1: 15.

Third, we should know two special periods.

12, the minute hand and the hour hand coincide.

At 6 o'clock sharp, the hour hand and the minute hand are in a straight line.

Fourth, it is not enough to know the time, but also to be able to draw and calculate.
