The researcher did an repaired action with using a puzzle media on identify two dimention space subject. Thus, the study aimed to describe the use of Puzzle as a medium to improve the score of mathematics in the material of identification of the characteristics of two dimensien space media in the fifth grader of an elementary school and to identify the difficulties in the learning process. This study was a classroom action research and the data were described quantitatively. The data of this study were collected through the observation and students’ final score, observation was used to analyze the percentage of teacher activity in the class while the students’ final score was aided to know the students’ improvement.
