This paper explores the use of gamification in math lessons for children in order to highlight the relationship between math education and its application to society. In school education, there is an existing problem about how to relate concepts learned in math to everyday life. One of the reasons for this problem is that it is difficult for teachers to set appropriate questions for students. We investigated a classroom using gamification intended for elementary school sixth grade students (34 people). As a result, it is argued that gamification is effective in math education.
