“Mom bought 5 cakes, how to divide them equally among 4 children?”

Mathematics has many interesting things. Because it is not only a dry lecture 1 + 1 = 2, but also forces employees to use their brains and practical knowledge for even seemingly simple problems, including only basic addition – subtraction. – multiplication.

If you don’t believe it, let’s see the story of a primary school math teacher (China) who is moving many netizens. Specifically, the teacher gave a topic to the students: “Mother went to the market to buy 5 cakes for 4 children. Ask how to share the most fair and reasonable?”.

Question: Mom bought 5 cakes, how to divide them equally among 4 children?, only 1 student got it wrong but made the teacher cry - Photo 1.

Obviously, this is a purely computational exercise and the solution is quite simple. The correct answer is that each son takes a portion of the cake. Then, with the only cake left over, we just need to cut the cake into 4 equal parts and divide it equally among 4 children. This way of dividing the cake is the most fair because the 4 children all receive the same share of the cake.

Most of the students followed this solution and got a perfect score. However, there was only one question that the student had the opposite answer to all the students in the class. The boy wrote: “Each child takes a piece of cake. The rest of the cake is given to his mother.”

There are no sublime mathematical formulas to be applied here. Even this student’s answer completely deviated from the teacher’s original answer. But just the detail that the student always remembers to give a piece of cake to his mother made the teacher moved and shed tears in class.

The answer of this 2nd grade student was passed on to other teachers in the school by the teacher, making everyone touched with the sincere and emotional thoughts of the student.

On Chinese social networks, many parents also praised the students’ unique way of solving homework. Besides, there are also people who think that the boy is an obedient child and receives great love from his mother.

AQ account commented: “It is still not possible to determine whether this boy is smart or bad at math just by solving this exercise. However, compared to other children, I believe that he is a filial son and must love his mother very much. there”.

Shared ND account: “The solution of the 2nd grader makes many adults think. The teacher said that the best answer divides the last cake among 4 children, but shouldn’t we in life share the cake with the mother as well? I still know that math exercises have only one answer, but when applied to life, you will find many ways to solve them.”

And you, what do you think about the student’s solution?
