Implementation of Teacher-Made Mathematics Learning Media on Integer Counting Operations

This study aims to identify the teacher-made mathematics learning media on integer arithmetic in elementary school. Employing a quantitative description approach with descriptive statistics for data analysis, this study obtained the data from tests and interviews. The result revealed that from 12 students who were given the test, there were 11 students who obtained above minimum mastery criteria set by the school, which is 75 or 91.6% of students who completed. Additionally, classical completeness reached 86.6%, above the provisions. All in all, teacher-made media is particularly effective in building up student's learning outcomes in primary school.
