  • The ability to calculate integer operations on a grade IV SD Negeri Patereman 2 Modung still quite low as seen from the student learning outcomes, where the averageclass has not reached Kriteria ketuntasan Minimal (KKM), so the need for increased efforts through the media number card. This research aims to know the: (1) the use of media card numbers to improve operating ability to calculate an integer class IV SD Negeri Patereman 2 Modung Bangkalan and (2) the result of te upgrade operation to calculate the integer IV SD Negeri Patereman 2 Modung Bangkalan. This research uses qualitative research with this type of class action research (PTK). As dara sources, selected grade IV SD Negeri Patereman 2 school year of 2017/2018 which amounted to 14 students.

Pre stage action is done with data capture learning outcomes teacher, while stage of the action carried out by researchers in two cycles, each consisting of 2 meetings. The results showed: (1) use the media card numbers can improve the operation of the integer count views of learning outcomes grade IV SD Negeri Patereman 2 Modung. (2) the upgrade operation to calculate integer students using media card numbers seen from the increase in the average value of a class from 69,6 be 80. The results of this research, mediacard numbers suggested was used as a reference in the implementation of learning especially in the subjects of mathematics as well as develop other learning media can support the success of learning.
