Children who start to learn Olympic mathematics in the fourth grade can't keep up with the teaching materials in the fourth grade. How about changing textbooks in grade three?
No, it is to re-measure his mathematical olympiad foundation and find a textbook suitable for him.

For example, if the fourth grade can't finish the content of the fourth grade independently, it means that the foundation is still very poor, so it is recommended to lay a solid foundation.

If he can handle the third grade, he should start from the third grade. This is normal. Many sixth-grade students can't do the first-grade Olympic math problem, so they can do any level problem, regardless of grade.

Let children learn by analogy, which means that children should have learned knowledge in school, and hope that children can expand. However, in all the introductory textbooks of Olympic Mathematics, it is the most basic to draw inferences, and ordinary children can complete this tutorial independently.

According to your description, your child can't handle the fourth grade content by himself at present. My suggestion is to have a good look at the textbooks and master the knowledge points before learning extracurricular knowledge.

Essence of Olympic mathematics

profit

The Olympic Mathematics is relatively in-depth, and the vigorous development of mathematical olympiad has greatly stimulated children's interest in learning mathematics, which has become a useful activity to guide them to be positive, explore actively and grow healthily.

There are many practical problems, such as counting, graph theory, logic, pigeon hole principle and so on. To solve this kind of problem, it is generally necessary to analyze and summarize the mathematical significance of the actual problem, abstract the actual problem into a mathematical problem, and then use the corresponding mathematical knowledge and methods to solve it.

function

In this process of constructing mathematical model, students' ability to look at and deal with practical problems from a mathematical point of view can be effectively cultivated, students' awareness and ability to solve practical problems with mathematical language and models can be improved, and students' ability to reveal mathematical concepts hidden in practical problems and their relationships can be improved.

In this creative thinking process, students can see the practical function of mathematics, feel the charm of mathematics and enhance their sensitivity to the beauty of mathematics. Today, with the emphasis on quality education, this educational function of Olympic mathematics has more important practical significance.

shortcomings

Because of the emergence of various private competitions, "Zhankeng Class" developed violently, and most students began to hate math and Olympiad.
