There have been a few mathematic education programs that based on operating activity considering cognitive development level of elementary student, although we can find a variety of computer-aided mathematic teaching methods for elementary school. The purpose of this paper was to examine the effect of mathematical program based on operating activity developed as teaching materials in plain figures. As results of the post-achievement test and attitude test, it was found that the math program has been improved the achievement positively. By a result that inspects mathematical learning attitude of the experiment group, it was found that variable factors such as interest, confidence, self-learning were changed significantly more important in statistics.
