The purpose of this study examines effects of repetition (spiral) as a teaching method to make students re-learn math in learning activities on students' fixings of basic and fundamental knowledge and skills and their motivation. Spiral employed as a teaching method in this study means to make students offer opportunities to re-learn math already learnt in math learning activities for students' fixings of basic knowledge of math. In Japan, we have problems about uses of students' skills or abilities for target problems and their motivations to learn. Thus, this study set an opportunity for re-learning by dealing with units/contents already taught to them in the introduction of new content in math teaching. Additionally, exercises in math in the beginning of class and assessment tests were implemented regularly. Findings reveal that 85% of students are more likely to feel positive effects of spiral teaching in 9th grade math lessons and acquisition of basic math skills through this teaching. Therefore, this study suggests that the use of spiral as a math teaching method makes students fix their basic and fundamental skills of math.
