Practical ability is "the subjective condition that people can be competent for a task in the conscious activity of transforming society." Primary school mathematics practical ability, that is, the subjective conditions for students to solve problems in the activities of learning and applying mathematics knowledge. "Mathematics Curriculum Standards" clearly points out: "Effective mathematics learning activities can't rely solely on imitation and memory. Hands-on practice, independent exploration and cooperative communication are important ways for students to learn mathematics. "This requires that our primary school mathematics teaching should pay attention to the cultivation of students' practical ability and promote the all-round development of students.

Pupils are in the primary stage of thinking development, and many senses can't coordinate their actions. Psychological research shows that children's wisdom is concentrated at the fingertips, and thinking begins with action. This also shows that the development of students' thinking should start with hands-on activities. Therefore, teachers should organize and guide students to carry out practical learning activities as much as possible in teaching activities, so that students can observe, think, find and solve problems in learning practice activities. Studies have shown that the development of students' thinking ability in this environment is much faster than that of a single listening and speaking method.

Create a happy learning atmosphere and promote the rapid development of thinking

People are open-minded in a happy environment. Einstein once said that imagination is more important than knowledge. To let students give full play to their imagination, we must first make them happy physically and mentally. This requires teachers to create a relaxed and happy learning environment for students, and then give effective and reasonable guidance for students to imagine reasonably. This can not only cultivate their logical thinking ability, but also improve their learning enthusiasm, thus shortening the time to solve problems and getting twice the result with half the effort.

Give play to the multiple functions of activities

Although the class type of each class is single, the activities should be flexible and diverse, and various activities will also play their different functions. Summarize the following ideas: 1. We can help students to know and understand through teaching, picture display, demonstration experiment and other activities. 2. Stories, sketches, dialogues, competitions and other activities can be used to improve students' interest in learning. 3. When strengthening memory, you can use activities such as analysis, induction and recitation. 4. While exercising the subjective consciousness, cooperative learning activities can be carried out to let students learn to be independent in cooperation. 5. When cultivating team spirit, we can carry out activities such as group competition and research study. When you are relaxed, you can do some relaxing exercises by playing music.
