First of all, the teacher told a short story about the application problem: the first-grade students in primary school are in the growth stage, curious and in the transition period from kindergarten to primary school. Therefore, in mathematics teaching, teachers should have enough patience to guide students to learn more. In math class, teachers can change application problems into short stories to stimulate students' thinking and attract their attention.

Second, guide students to operate: the main way for ordinary primary school students to acquire knowledge is through brains and hands-on. Therefore, teachers need to design corresponding teaching experiments to help students acquire mathematics knowledge.

Third, create mathematics teaching situation: learning is a process of communication and integration between teachers and students and between students. Among them, the subject of learning is students, who are creative, active and independent, while the content of teaching materials is closed and passive. One of teachers' tasks is to make boring textbooks lively and enrich teaching contents in various interesting, open and energetic learning activities.

Fourth, set differentiated learning goals: traditional mathematics teaching in the lower grades of primary schools is mainly based on textbooks, but it is always limited to this range. The single teaching content reduces students' interest in learning, which leads to students' failure to improve mathematics in primary schools. Teachers can turn their goals to middle schools, refer to the teaching mode of middle schools, and start to implement classified thematic learning from the teaching content of lower grades of primary schools, so that students have more room for independent choice.

Precautions:

First of all, it is very important to teach children to count from an early age. Then, when the child can count from 1 to 10, he can be taught to count objects. For example, the stool at home, the apples on the table, and the candy given by the teacher. Then wait for the child to come home, count the number of people in the family, cook some dishes, go to the supermarket to buy some things, and let him count as long as he has the opportunity, don't bother. Only when it is applied to objects can children have the concept of number.

Children should keep in mind that the methods of "9-to-0/","8-to-2", "7-to-3", "6-to-4" and "5-to-5" are simple and easy, and the thinking process includes "looking at large numbers (looking at large numbers), dividing decimals (looking at decimals), doing ten and adding even numbers".

Teach children from a simple beginning, such as 1+ 1=2, 1+2=3. First, with physical objects, such as 1+ 1, you can get 1 apple and 1 apple.

Teach children to count objects first, not with their fingers. To deepen the concept of numbers, we should first let children calculate in kind and then teach them to use their fingers. Otherwise, children will rely on their fingers and don't understand the true meaning of numbers.
