An interesting math class

On Friday, the school leaders came to the class and said, "Go to the multi-media classroom next Monday. Each person will bring a deck of cards and an A4 white paper. The principal will attend the class."

The class bell rang, and the school leaders sat in their seats and listened to the teacher very seriously. The teacher told me how many cards there were; there were several colors; there were several suits; how many of each suits were there; we all answered the basic questions with the teacher.

The teacher then said that 52 cards represent 52 weeks in a year. The four colors represent the spring, summer, autumn and winter seasons. There are 13 suits, and the sum of the 13 cards is 91. Days, representing a season is 91 days, the sum of the four colors and the addition of Xiao Wang is 365 days, is the number of days in a year, plus the king's point is 366 days, is the number of days in the next year. After the teacher finished speaking, we asked us questions. The students all rushed to answer the teacher. The school leaders looked at us seriously and were very happy. They were applauding.

This is a very interesting math class that reminds me of the hidden secrets in playing cards.
