Abstract
Mathematics learning is learning that develops student creativity to improve thingking skills, construct new knowledge to increase good mastery of mathematical material. In learning mathematics there are several obstacles, namely low student achievement, lack of student motivation and students still think that mathematics is difficult and difficult to learn. To overcome these obstacles there is a solution for learning mathematics that is using Realistic Mathematic Education (RME) assisted by the number of hours in the addition operation material. By using Realistic Mathematic Education (RME) assisted by number hours, it is expected to be able to improve student learning achievement in the addition operation material at SDN Batulawang. This research uses quantitative research using quasi experimental methods with the Nonequivalent Control Group Design. This research was conducted in SDN Batulawang with a population of thirty people and used a systematic sample that divided students into two classes using even odd numbers, so that the control class was fifteen people and the experimental class fifteen people. Data collection techniques were carried out through pretest and posttest. Data were analyzed using SPSS.

Summary
Sugiyono (2016: 14) penelitian kuantitatif adalah penelitian yang digunakan untuk meneliti populasi atau sampel tertentu dengan teknik pengambilan sampel secara random, pengumpulan data menggunakan instrument penelitian dan analisi data bersifat statistik yang bertujuan untuk menguji hipotesis yang telah ditetapkan. Sedangkan metode yang digunakan pada penelitian ini yaitu metode eksperimen. Penelitian ini menggunakan validitas konstrak yang dalam pengujiannya dilakukan dengan cara meminta pendapat para ahli atau sering disebut judgment experts. Dalam penelitian kuantitatif teknik analisis data yang digunakannya yaitu menggunakan statistik. Uji homogenitas dilakukan untuk mengetahui subjek populasi dalam penelitian bersifat homogen atau heterogen dengan ketentuan Jika Fhitung > Ftabel, berarti tidak homogen dan jika Fhitung < Ftabel, berarti homogen. Jika Ho: μ1 = μ2 maka tidak terdapat pengaruh atau perbedaan yang signifikansi antara kelas kontrol dan kelas eksperimen. Jika Ha: μ1 ≠ μ2 maka terdapat pengaruh yang signifikansi antara kelas kontrol dan kelas eksperimen
