This research based on weaknesses of mathematic comprehenssion skills on student elementary school. This problem happened, because the student not active at the study. Mathematic comprehenssion is a skill to absorb and understand ideas. Remembered mathematic comprehenssion siklls that so important, need an effort to increase that mathematic comprehenssion skills, one of them alternative to solve the problem use the model Discourse Multy Reprecentasy (DMR). DMR have an orientation to contruction and USAge media with group study setting. This reseach aims to know (1)the improvement mathematic comprehension skills about use the model DMR study, (2) a differently about DMR study with convensional study. Population in this reseach are student at grade V in Cileunyi Subdistrict. Then Sample this research that 30 studen at grade V Cimekar elementary school as experiment class and 30 student at grade V Sukarasa elementary school. Sample choosen by sampling purposive tehnichque. Reseach method that use Quasi Experiment type Nonequivalent Control Group Design. Instrument in this reseach used quesion test comprehenssion mathematic skills, after that data analyze use t-test and the observasion page analyzing by descriptive. This reseach result indicate that: (1) exist a escalation comprehenssion mathematic skills to student after given a treatment with DMR, (2) exist a different divide DMR and convensional. This is evidenced by the comparison data gain of experiment class an control class of 0,4739 and 0,1844. Model DMR can be used in an effort to improve students mathematic comprehenssion skills.
