As the phrase often expressed by the experts, that: I heard then I forget, I see then I know, I do then I understand. That's why in the teaching of mathematics in elementary school (SD) is still required the use of props. As teachers we need to know the various props that can be used in teaching mathematics subjects, especially in teaching mathematics in elementary. Mathematics subjects on the implementation should be pursued with conducive learning conditions in the sense of an active learning, creative, effective and even innovative.
