Knowing clocks and watches is a math course in the second grade of primary school last semester. The essence of mathematics comes from life and is also used in life, so many common scenes in life are not difficult for children to learn.

For many preschool children, the intellectual development has completely reached the stage of knowing clocks. After knowing clocks, children will have a deeper understanding of time and a more convenient life. Therefore, as long as children are willing to learn, it is ok to know clocks earlier.

1, know the three pointers on the table.

First, find a clock with an hour hand, a minute hand and a second hand for your child. Tell the children about the composition of time first. For example, now it is 8: 15, so it can be said that it is 8: 15. Then show it to the children. Of the two black hands on the watch (the color of the hands can be adjusted according to the specific situation of the clock), the short one is the hour hand, indicating what time it is; The long minute hand indicates the present time.

2. Know the time.

Then I began to know the time of the hour, such as five o'clock sharp and eight o'clock sharp.

You can tell your child that when the minute hand points to 12, the hour hand must be aimed at a certain number, and what time is it?

Step 3 spend half a minute getting to know each other

Then start to know for half an hour, such as 3: 30 and 9: 30.

When the minute hand points to 6, it means that half an hour has passed. What time is it now?

At this time, the hour hand will just point to the middle of two adjacent numbers, and the hour hand should be pronounced as the smaller of these two numbers. For example, when the hour hand points between 3 and 4, it should be read as 3: 30 (except in one case, when the hour hand points between 12 and 1, it should be read as 12: 30).

The difficulty of learning at this stage has increased. Let the children get familiar with 1-2 days and master it skillfully before continuing.
