This study begin form observation that done by researcher to math learning of fourth grade student of SDN Jeruk II Surabaya. Researcher find some problem, there is much of student still can'n finishing task of integer arithmetic. Teacher role also less optimal in creating effective learning. Teacher have not enclosing learning media as a guiding tool in conveying learning material to student. Teacher tends to focused with the implementation of lecture method so there is no feed interaction between teacher and the student. That causeing study result of student on integer arithmetic operation is low. Based on those problem, it need solution to solve it. Solution that proper with those problems is the utilization of learning media, in this case is the colourful picture media. The purphose of this study is to describe teacher activity, student activity, and student study result with applying colourful picture media. Math learning is learning that related with idea, process and logical reasoning that aimed to help human in understanding and mastering social economy, and nature problem. Learning media is teacher aid tool in conveying material/information/ message to student during learning process. This study use descriptive quantitative method. Data collection in this study using observation technique and test. Teacher activity experience improvement during two cycle, on first cycle is 70% and on second cycle increase to 95%. Student activity experience improvement during two cycle, on first cycle is 70% and on second cycle increase to 95%. student study result experience improvement during two cycle, on first cycle is 65% and on second cycle increase to 90%. It can conclude that applying colourful picture media can increase student study result on tnteger arithmetic operation on fourth grade student at SDN Jeruk II Surabaya.
