Understanding Elementary School Students' Errors in Completing Number Operations

Integer operations are fundamental in math; students need to know how to do them before learning other things. However, students often have difficulty learning the material of integer operations. This study aims to describe the types of errors students have made in solving integer operation problems and suggests efforts that can be made to overcome these problems. This research was carried out on students at SD Negeri Pacing I Sukosewu. The study involved 19 students. The research instrument used were documents and diagnostic tests in the form of descriptive questions. The data analysis used was in the form of descriptive statistical analysis. The results showed that student errors in solving integer operation problems were reading errors at 26.32%, comprehension errors at 41.05%, transformation errors at 57.89%, process skill errors at 57.89% and conclusion drawing errors at 42.11%. One of the learning alternatives that can be used to minimize at SD Negeri Pacing I Sukosewu is guided discovery learning that involves the students’ real world.
