First, how to cultivate a sense of numbers
1. Cultivate the sense of numbers in activities. The cultivation of number sense cannot be achieved overnight. Teachers and parents should make use of the materials around students and try their best to awaken students' existing life experience through colorful life situations, so that students can feel and discover themselves in activities such as operation, observation, guessing and communication, thus establishing a sense of numbers.
2. Cultivate a sense of numbers in estimation. Estimation is actually a mathematical imagination and a strategy for people's thinking to explore the laws and essence of mathematics. Estimation can shorten the time of solving problems, gain the opportunity of mathematical discovery, exercise mathematical thinking and cultivate a sense of numbers.
3. Arousing a sense of number in communication is a spiritual feeling, and students can develop a sense of number in full communication.
Second, what is the value of number sense?
1, establishing a sense of numbers is helpful to improve students' mathematical literacy. It is an important symbol of students' mathematical literacy that they learn mathematical thinking and have mathematical sensitivity to understand and explain practical problems.
2. Building a sense of numbers helps students to build their own mathematical knowledge. Number sense is the network structure of number concept, and the formation and stability of the network structure of number concept is the key to the establishment of number sense. The establishment of number sense helps students to build their own mathematical knowledge.
3. Establishing digital consciousness is helpful to cultivate students' innovative spirit and practical ability. In the process of building a sense of number, students have many opportunities to contact and experience real problems, exchange personal views on logarithm-related issues with others, and think and solve the same problem in different ways. This will help to cultivate students' innovative spirit and practical ability.
Third, what is a sense of number?
Modern mathematics: "number sense" comes from English "number sense" and can also be translated into number sense or number consciousness. At present, people's understanding of this concept is diverse. From the relevant discussions of scholars at home and abroad, it can be observed that intuition about quantity is called number sense; Sense of number is an intuition about number, which can be expressed by expressing all the different meanings of number;
Sense of number is a general understanding of logarithmic sum operation, which can help people to make mathematical judgments with flexible methods and get useful strategies to solve complex mathematical problems (Ma et al., 2002); Sense of number can be understood as sensitivity and discrimination to numbers (quantity) (Zheng Yuxin, 2002); People's understanding of the correlation between numbers and their ability to solve digital problems flexibly are called the feeling of numbers or the feeling of numbers.
