1. Stimulate the interest in learning mathematics. Children will be interested in what they are familiar with, so we should start with what children are familiar with and introduce new knowledge. So the learning effect will be better.
2. Develop good habits. The logical thinking of mathematics needs organization, and the cultivation of good study habits is the cultivation of children's organizational ability. At the beginning of the third grade, we should pay attention to cultivating mathematical thinking and know how to draw inferences from others. Encourage children to communicate and express their ideas boldly, learn to express and communicate in mathematical language, and encourage children to express their understanding in order to better pay attention to their mastery of knowledge.
3. The calculation foundation should be firmly laid. You can't just know mechanical calculations. Let children understand the truth and why in basic calculation, and you will know why. Grasping children's memory characteristics, the first impression of learning is very important. The first impression of knowledge is correct, and later learning will be smoother. If there is a deviation in accepting knowledge for the first time, this false impression will not be easily eliminated.
4. Pay attention to practical activities. Cultivate children's ability to use mathematics. Connect mathematics with life, for example, when buying vegetables, you can learn to think about the unit price of vegetables, the total price of the last flowers, etc., and deepen your understanding by connecting with life.
