Number of new calls in the nth minute: it is the total number of all players and teachers who have received the notice before.
It takes at least 6 minutes for 50 people to play, because the sixth power of 2 is 64 people, including teachers, and 64 MINUS 1 = 63 people, excluding teachers.
The legal provisions are as follows:
1. The number of newly notified players per minute is exactly the total number of all notified players and teachers, that is, the number of newly notified players in the nth minute is equal to the total number of notified players and teachers in the previous (n- 1) minutes.
2. In the nth minute, the total number of all notified players and teachers is a geometric series, and the general formula is an=2n.
3. In the nth minute, the total number of notified players is (2n- 1).

Primary school mathematics is to teach children a series of knowledge about number, four operations, the calculation formula of figure and length, unit conversion and so on through textbooks, which lays a good mathematical foundation for junior high school and daily life calculation. Frieden Noel, a Dutch educator, said: "Mathematics comes from reality and must be rooted in reality and applied to reality."
Indeed, modern mathematics requires us to observe the world from a mathematical perspective and explain the world in mathematical language. Judging from the mathematics learning psychology of primary school students, the learning process of students is not a passive absorption process, but a reconstruction process based on existing knowledge and experience.
Therefore, learning while doing and learning while playing will make children learn more actively. From our educational goal, while imparting knowledge, we should pay more attention to cultivating students' comprehensive ability of observation, analysis and application.
