Many teachers' teaching practice for many years shows that students' interest in playing games should be appropriately transferred to the classroom so that they can fully experience the fun of learning and have enough interest in learning. Junior students like talking, laughing, moving and playing. If this characteristic of students is ignored in teaching practice, classroom practice is just cramming, which may make them feel that the classroom teaching content is boring and can not achieve good teaching results. We can play the following games to improve students' interest in class, such as finding friends, winning red flags and driving. For example, when I say "Know 8", I consolidate the study of 8' s composition knowledge through these different game activities. The teacher and his classmates compete. The teacher takes out a digital card (the teacher shows it to the students gradually), and all the students and the teacher say the numbers made up of the digital card together. When playing this game, the students are more attentive. There are few mistakes. If everything students say is right (of course, nothing is wrong), they can get grades. As long as there is even one mistake, the teacher will deduct points. Whenever they win, the students applaud happily. Using various forms of games to teach junior students highlights the flexibility of teaching, improves students' enthusiasm and initiative, and students learn very easily and happily. Good teaching results can be achieved. The teaching practice in recent years has fully proved that a strong interest in learning can urge students to study more urgently, stimulate their enthusiasm for learning, greatly improve the teaching quality and effectively develop their thinking.
