We have taken a class on an isoperimetric problem for lower secondary school students who have high motivation to mathematics. In this paper, we have considered the lesson plan on an isoperimetric problem for the students and decided the goal of this class is to prove the theorem as below. 'A polygon which has the biggest area with same constant perimeter is a regular polygon.' After the class on an isoperimetric problem, we have realized the goal of isoperimetric problem for lower secondary school students will be suitable and have recognized strongly the mathematical experiments will be an important impact for this class.
