Children don't know clocks, we can take the following steps to teach:
Start with long and short needles: Tell your child that the long hand means "hours", the short hand means "minutes", that the hour hand goes one number, and that the minute hand goes one circle. While looking at the clock, it is more effective to explain at the same time. 
Teaching and learning in concrete lifeFor example, the time to wake up each day, the time to eat snacks, what time the child's favorite cartoon starts, etc., in these specific behaviors to consciously guide the child's concept of time. 
Associate time units with counting units: Parents can use the watch to keep time, walk by the second and say: "l second, 2 seconds, 3 seconds", through this counting method to let the child perceive the passage of time. At the same time, tell your child what he can do in 1 minute, for example, 1 minute to set the plates, 2 minutes to go downstairs, 5 minutes to sing a song, 10 minutes to set up the blocks, 15 minutes to read a book, etc. 
Learn with picture booksParents may wish to buy picture books about the concept of time with their children to strengthen their children's concept of time and make it more interesting to know time. Use games to teach: Some learning styles are more effective in deepening understanding, such as games. By simulating some scenarios, children can understand the concept of time in practice. 
Create a scenario exercise: You can use some situations from everyday life, such as using a clock to indicate the time you wake up in the morning, the time to eat, the time to go to school or work, etc. Study in units of 5Because children sometimes can't understand why the long hand points to 1 for 5 minutes instead of 1 minute. If you teach in increments of 5, it will be easier for children to understand. Learn how to represent time in a clock: Master the hour and minute hands of a clock, where they point at different moments, and the time of day represented by a circle of clocks. Practice a lot: especially to practice reading where the hour and minute hands are pointing. Exercises can be done using analog clocks or real clocks.
In addition, children can also be taught to know time through stories, nursery rhymes and other ways. It is important to be patient, understand your child's progress, and provide help and guidance on an ongoing basis.
