Because the game adopts the best of three games system.

The king of Qi only needs to win two games to win, and the result of the draw is the same.

Later, Tian Ji lost to Youma with inferior horses, won to Zhongma with superior horses, and won to Youma with inferior horses.

Suggestions on the Evaluation of Mathematical Tian Ji Horse Racing

Advantages and disadvantages of Tian Ji horse racing commentary;

Advantages:

1, the teaching design is novel and unique.

At the beginning of the class, teachers fully grasp the students' interesting and playful nature and design stories to introduce new lessons. The method is ingenious and the classroom atmosphere is active. The design of this link is successful.

2, reflect the strategy to solve the problem.

The teaching process is vivid and smooth, with distinct levels and solid and effective activities.

Teaching them knowledge through activities highlights students' new concept of solving problems. The teaching process is scientific and reasonable, cooperative learning is solid and effective, and communication evaluation is in place, giving students enough time and space for communication and discussion. Moreover, teachers also participate in students' group activities and truly become participants in students' learning.

The initiative of positive thinking is also completely in the hands of students. In the information exchange and activities between teachers, students and students, when students are faced with practical problems, teachers can guide students to try to use the knowledge and methods they have learned to find strategies to solve problems from the perspective of mathematics, which promotes the complementary interconnection of knowledge, enables students to learn to listen, learn to empathize and learn to find optimal solutions in various schemes.

It improves students' ability to solve problems and gives full play to their intelligence. Students experience the mathematical thinking method of operation in independent exploration and cooperative communication, and cultivate the sense of optimization.

3. It embodies the teaching idea that mathematics comes from life and serves life.

The arrangement of the whole teaching content is familiar to students. Teachers should guide students in time in life, be good at thinking, pay attention to strategies, let students feel the extensive application of mathematics in daily life, and try to solve simple problems in life with mathematical methods.

Disadvantages:

The mathematical wide-angle "Tian Ji Horse Racing" is a "countermeasure problem", which is the content of comprehensive practice and application of mathematics, and it is a relatively systematic and abstract mathematical method.

Primary school students' thinking is mainly concrete thinking, and they are not ready to learn this knowledge comprehensively. So when I first chose this course as an open class of the Spring Rain Cup Speech Contest, the teachers in the same group said that this course was difficult for students to learn.

In teaching design, we should pay special attention to how to change the difficult into the easy, and choose a teaching method that makes students interested and easy to understand.

Probability of Mathematical Problems in Tian Ji Horse Racing

If both sides arrange horses at will, the probability of Tian Ji winning is 1/6.

If the two sides have the order of appearance, such as Tian Ji coming out later, then the probability of Tian Ji winning is1; If Tian Ji goes first, the probability that Qi Weiwang will win is zero.

Everyone can take 1~4 cards at a time, which means they can take up to 5 cards at a time. So as long as you take four first, and then no matter how much your opponent takes, you win with one.
