Benefits of special exercises in mathematics
First, pay attention to the practice of special knowledge points, highlight key points and lay a solid foundation.

The teaching of examples and exercises is the main link of mathematics class, and its effectiveness determines the degree of implementation of teaching objectives.

Examples and exercises are not only classics of solving problems with knowledge, but also models of thinking training.

When explaining new knowledge, teachers can highlight key points with examples and carry out targeted special knowledge training.

Second, excavate the connotation of the topic and cultivate the thinking ability?

Live "-flexible use, broaden thinking and cultivate multi-directional thinking. ?

After the new knowledge points are initially strengthened by individual exercises, teachers should do in-depth exercises according to the content of the textbook, broaden students' thinking and cultivate their flexibility in solving problems through multi-angle analysis.

Exercise is an important part of mathematics teaching in primary schools, an indispensable link in students' learning process, the main means for students to master knowledge, form skills and develop intelligence, an effective method to improve students' ability to solve simple practical problems with knowledge, and the main way for teachers to understand students' knowledge. High-quality classroom teaching must be based on high practical quality. Specifically, on the one hand, exercises help students to deepen their understanding of mathematical knowledge, form a good sense of numbers, a scientific way of thinking and a reasonable habit of thinking, understand some important mathematical relations, laws and ways of thinking, and cultivate their initial sense of application and innovative ability; On the other hand, it also helps students acquire the necessary skills, thus laying the foundation and providing support for subsequent study and problem solving. At the same time, appropriate exercises can also help students build up their confidence in learning, feel the rigor and certainty of mathematics, improve their ability of expression and communication in mathematical language, and then form correct mathematical concepts.
