Parents should instill the concept of numbers into their babies, and how much they should understand first. I have a concept of difference in my mind, which is the basis of the concept of number. For example, instead of letting him count at a loss, it is better to give him a chance to compare numbers from time to time. Concepts such as more or less, light or heavy, big or small, far or near, long or short, deep or shallow can be better understood by comparing objects. The 5-year-old baby is also interested in calendars and clocks, but the concept of time is still vague. If the exact time is mentioned in the answer, it's just imitating what adults say. For example, you ask him: When will the kindergarten have a holiday? When do you eat snacks? When is your birthday? He can answer all the questions, but what day is after Tuesday? When do you go to school? When do you watch TV? I often can't answer. How to cultivate the mathematical ability of 5-year-old children, parents should know that the baby has no clear concept of time, but is imitating what adults have said. And the baby is sensitive to specific time points only because it is related to something in life. It should be said that the baby at this time can clearly distinguish the past and the future, but it can't grasp the passage of time and the specific time. You still can't get him back at the right time.
