The main object of this paper is to explain the voting method.
The method is the method which makes everyone happy.
When I came up with this idea, I was remembering the memories of the social choice that is tough for elementary school students.
So, I considered how we do to decide the choice fluently in a small class of a lot of elementary school students.
A lot of elementary school students are selfish and don’t listen to other people’s opinions.
I will think of the method to make decisions that all student’s opinions was taken into account.
