1. Help to understand the concept and relationship of numbers with the help of things in life. For example, we can understand the concepts of integers and decimals by observing the number of articles, and understand the size and comparison methods of numbers by comparing the values such as height and weight.

2. Through a large number of mathematical activities, we can cultivate the perception of the size of numbers and the ability to calculate numbers. For example, through basic operations such as addition, subtraction, multiplication and division of numbers, we can cultivate our ability to perceive and operate numbers.

3. Get mathematical knowledge through reading mathematical stories, participating in mathematical competitions and other channels, and constantly accumulate mathematical knowledge and improve mathematical literacy.

Expand knowledge:

Sense of number is a basic mathematical literacy, which refers to the ability to understand, perceive and use numbers and mathematical concepts. Just as people have an intuitive perception of the shape, color and size of objects. Sense of number is people's intuition and sensitivity to numbers in a certain range. People with a good sense of numbers can usually understand mathematical problems quickly and accurately, and use appropriate mathematical methods to solve them.

Improve the ability of mathematics understanding and application. People with a good sense of numbers can usually better understand mathematical concepts and problems, and can flexibly use mathematical knowledge to solve practical problems. This is helpful to improve math scores and application ability.

Enhance your confidence in mathematics. People with a good sense of numbers are usually able to face math problems more confidently and will not give up because they are afraid of difficulties. This self-confidence also helps to improve the learning effect of other subjects. Cultivate logical thinking and creativity. People with a good sense of numbers usually have strong logical thinking ability and creativity.

In the process of solving mathematical problems, we need to use logical thinking and creativity, which is helpful to cultivate these abilities. Enhance the ability to solve problems. People with a good sense of numbers can usually make better use of mathematical knowledge and logical thinking to solve various practical problems. This ability is of great help to daily life and work.
