Abstract This study aimed to (1) describing Learning of the mixed integer operation in IV grade,(2) The students' ability in completing the mixed integer operation, (3) The constraints which were faced by students in completing the mixed integer operation and the solutions to overcome those obstacles. The type of this study was descriptive quantitative and qualitative research. The subjects of this study were the fifth grade students of SD Negeri 6 Banjar, consisted of 20 students and teachers in IV class. The object of this study were (1) Learning the mixed integer operation in IV grade, (2) The students' ability in completing the mixed integer operation, (3) The constraints which were faced by students in completing the mixed integer operation and the solutions to overcome those obstacles. The observation, test, interview, and documentation were used to collect the data. The data were analyzed using descriptive quantitative and qualitative approach. The results showed (1) Learning the mixed integer operation was categorized good with a value of 80 , (2) the average test results in classical 62.7 with low category with the highest indicators is to solve everyday problems which involves multiplication of various fractions 55.25% and the lowest indicator is determining the results of the mixed integer operation of various fractional 88.5 %, (3) The constraints faced by students are: forget the concept of the mixed integer operation operations, forget to put coma at the end of the answer and students are still confusein completing the essay task. The solution to overcome those constraints aregiving students a lot of exercises regarding the mixed integer operation fractions. So that students are better trained and familiar with the particular multiplication exercises.
