Mathematics is a science that is universal and able to integrate with other subjects. One of the goals of mathematics learning based on Kurikulum Tingkat Satuan Pendidikan is to understand, explain and apply mathematical concepts in the context of problem solving. But in the field, the students tend to difficulties in resolving problems related to problem solving in mathematics. This is due to the low ability students in mathematical problem solving in students' learning because not used to thinking creatively. It required a real effort to improve students' problem-solving abilities in mathematics. One of the measures taken namely through mathematics model Multy Discourse Representation (DMR). Learning with models DMR is one alternative that can be used because it exposes students to work in groups, in order to issue a power of representation held by the students.
