In developing of creative skills important role has the educational process, which is especially evident in the school where students spend a lot of time. The school should encourage and develop creative thinking of each student, encouraging them in any attempt to create something new, to create a pleasant atmosphere in the classroom and educate teachers. In this kind of school, students are happy, successful and satisfied. The objectives of this action research were encouraging students' creativity, improving their creativity in finding of new methods in math lessons and creating a pleasant working atmosphere. The students were creative during the research, they were free to express their opinion and they successfully cooperated in the group between each other, which resulted by their progress in that area.

Pleasant working atmosphere, another result of the research, we have created by common and spontaneous free activities.
