Analysis of mathematics learning activities materials of operating skills of rapid number students in elementary school through online learning

This study aims to improve mathematics learning outcomes, especially in fractional arithmetic operations fifth grade students of SD Muhammadiyah 01 Paron, Ngawi Regency. In this study, offline and online models or what is often called Blended Learning will be implemented using case problems. type research descriptive qualitative research, the subjects are class Va Vb Elementary School totaling 19 20 from Vb, homeroom teachers principal Paron. The object outcomes elementary school students, on material fractions blended model learning. To test validity instrument data triangulation. were obtained observations, interviews tests. analyzed descriptively quantitatively qualitatively. results show that average still not effective because many constrained about mathematical concepts students' understanding numbers low. With this, a solution for concepts. who taught digital-based 70 while value conventional 57.5, it appears overall implementation process experimental more supportive mastering than classroom. control models.
