1. Olympic mathematics textbook of Renhua School (commonly known as "textbook", six volumes, from grade one to grade six).

This set of writing is very detailed, covering the basic content of primary school Olympic mathematics, and the content is not too complicated, which is very suitable for children to learn by themselves! If the child is unconscious, you can sign up for a class, let the teacher teach and supervise the child to firmly grasp the content. Every lecture in it has examples and exercises, which not only have answers, but also have solutions.

You can learn examples and then do exercises. Attention, practice must be done, everything must be done! Because you can't learn just by looking at math! It is more suitable for children in grade three to learn Olympic Mathematics from this set of books.

2. The Training Guide of Mathematical Thinking in Renhua School (commonly known as the "Guide", consisting of two volumes, one volume for grade three and four, and one volume for grade five and six).

This set of books is actually a problem set and a problem set. Most of the topics are difficult, and some are even IMO (International Mathematical Olympiad) topics. Moreover, the content inside is not completely arranged according to the difficulty of the topic, but according to the required mathematical knowledge.

This leads to a more troublesome problem, that is, the mathematical knowledge required for a topic may be very simple, and it may only require four integer operations that a third-grade child knows, but the difficulty of thinking about this topic is far from what a third-grade child can bear. Therefore, this series of third and fourth grade volumes must be used with caution.

Especially for children in lower grades, such as the third grade, if they start to learn thinking guidance, most children will find it "very" difficult, and because the topic is too difficult, they often learn half a word with little effect. Thinking leads to some problems in the third grade, which can only be explained to children after the fifth grade, and even many children may not fully understand them by the sixth grade.

3. Olympic Training Question Bank (commonly known as Question Bank Author: Liu Jingyou Press: Beijing Normal University Press).

"Liu Jingyou Question Bank" is named after its author Liu Jingyou. In fact, the correct name of this book should be "Olympic Training Question Bank". This is a problem set that contains many competition questions.

Applicable object: children with a certain foundation of Olympic mathematics.

Advantages of this book: the topics in Liu Jingyao's question bank are selected by many key middle schools. Children who have used this book feel relaxed in the exams of key middle schools and have great advantages.

The characteristics of this book: the types of questions are better, and a large number of real cup questions are integrated; The number of questions is large, and there are more than 2000 questions in statistics. The exercises in this book are marked with different symbols according to different emphasis and difficulty.
