The fastest runner is the second hand, tall and in good shape.

The slowest runner is the hour hand, short and fat.

Not high or short is the minute hand, and running at a constant speed is very effective.

Steps to teach children to know clocks:

First, teach the child to know the hour, set the hour hand, and the minute hand has been aligned with the number 12, so that the child can see the time.

Second, teach children to know what time it is, such as:

Half past six, half past eight and so on. Move the hour hand and fix the minute hand at 6 to let the child see the time.

Third, teach children about free time, such as:

6:

25,8:

55 and so on. The hour hand and minute hand fluctuate accordingly so that the children can see the time.

How to teach children to tell the clock?

According to the standard progress of primary school mathematics teaching, the first-grade mathematics teacher should teach children to know clocks and watches! How to distinguish the hour hand, minute hand and second hand?

What do they stand for running around?

When my daughter first came into contact with clocks, she was very confused. Later, I taught her a small formula to identify clocks and watches, and I remembered it clearly at once.

It seems that paying attention to learning methods can get twice the result with half the effort ~ teach children the following tips to know clocks and help them know clocks quickly.

First, know that the second hand is the fastest hour hand, minute hand and second hand. Tall and in good shape. The slowest runner is the hour hand, short and fat.

Not high or short is the minute hand, and running at a constant speed is very effective.

Second, know that the clock is one hour and 60 minutes, and half an hour is also called 30 minutes.

Look for the minute hand after reading the hour hand, and carefully divide the length of the pointer.

You can't walk in minutes, step by step.

The minute hand went half a turn to 6, and the hour hand went half a step.

The hour hand is not half a step, but also the number before reading half a step.

Every time the minute hand steps on 6, it is half a minute. Please remember.

Third, Brother Pointer can race. Brother Pointer can race, and the top 12 is the starting point.

Big brother's hand is slow and the minute hand is fast.

The minute hand ran a big circle, and the eldest brother moved slowly.

Fourth, the small dial is round and runs in circles.

The minute hand is long, the hour hand is short, one is fast and the other is slow.

The long pointer refers to 12 and the short pointer refers to several hours.

The long minute hand points to 6, and the short minute hand has just passed a few minutes.

Hello, I am a treasure mother who likes to play games with her baby. The baby is 2 years and 5 months old. I also look for some good ways to "know the clock and know the time" in my parenting experience. I made a plan for the baby and shared it with you:

If you directly tell children the principle of clock recognition, this is teaching, and children will have a burden when learning to recognize clocks; But if children learn to tell the clock in play, they will not only have no psychological burden, but also feel the fun of learning.

The first grade clock is coming 12.

Explain it with a formula.

Formula:

There is a number 12 on the clock face.

Line up in order.

Long minute hand, short hour hand.

When the minute hand points to 12.

When the hour hand points.

When the minute hand just passed 12, it just passed a little.

When the minute hand is almost 12, it's almost time.

What do you know about clocks?

The clock is a timing device and a precise instrument for measuring and indicating time.

Clocks are usually distinguished by the size of the internal machine.

According to international practice, clocks and watches with a movement diameter greater than 80 mm and a thickness greater than 30 mm; A pocket watch with a diameter of 37 ~ 50 mm and a thickness of 4 ~ 6 mm is called a pocket watch; Watches with a diameter less than 37 mm; A watch whose diameter does not exceed 20mm or whose movement area does not exceed 3 14m2 is called a women's watch.

The watch is one of the smallest, strongest and most sophisticated machines invented by human beings.

Structural form:

There are many structural forms of mechanical clocks and watches, but their working principles are basically the same. They are all composed of prime mover system, transmission system, escapement governor, pointer system and winding system.

Mechanical clocks and watches take clockwork as the power system, and drive the escape governor through a transmission system composed of a group of gears; Then the speed of the transmission system is controlled by the escape governor in turn; The transmission system drives the pointer mechanism while pushing the escapement mechanism, and the rotation speed of the transmission system is controlled by the escapement mechanism, so the pointer can indicate the time on the dial according to certain rules; The winding pointer system is a mechanism for winding springs or moving pointers.

In addition, there are some additional mechanisms that can increase the functions of clocks and watches, such as automatic winding mechanism, calendar (double calendar) mechanism, alarm device, moon phase indication and timing mechanism.
