In the first cycle by the students have been able to understand the concept (distinguishing example and not an example) as much as 57.58%, the students have been able to use the concept of the sum of as much as 69.69%, the students have been able to use the concept of reduction of as much as 42.42%,
and the students have been able uses the concept of a combined 60.61%. In the second cycle was obtained 96.97% of students have been able to understand the concept, 75.76% of students have been able to use the concept of addition, 72.73% of students have been able to use the concept of subtraction, and 78.79% students have able to use the combined concept. Based on the above inferred using comics media through STAD cooperative learning model can improve the understanding and use of the
