1, select the appropriate game content. When choosing game content, we should fully consider the age characteristics and existing life experience of students according to the needs of teaching materials. Otherwise, the game will not achieve its purpose or be difficult to unfold;

2. Define the purpose of the game. Games are just a way of teaching, not the purpose of teaching. In teaching, we should deal with the practice of methods and purposes. Not every teaching content, every class will design some games, which will only make the games a mere formality and worthless.

3. Design the rules of the game. Detailed rules of the game are the prerequisite for the orderly development of mathematical games. Teachers should formulate perfect rules and steps of the game according to the purpose and nature of the game;

4. Order should be "strict" when organizing games. Different games have different rules, and the rules of the game are put forward according to the game tasks. Every game participant must abide by these rules and play the game according to the requirements and steps of the game.

The proper use of game teaching in mathematics classroom teaching conforms to the psychological characteristics of primary school students' strong curiosity, hyperactivity and short concentration time, so that students can learn, discover, understand and master knowledge with their brains, mouths and hands in a relaxed and happy atmosphere, and achieve the trinity of teachers, students and knowledge. It is an important way to implement education by entertaining and entertaining education.
