Student's understanding of numbers through the number sense strategy

Abstract

Many students have difficulties to do arithmetic operations with fraction. One way to overcome student difficulties is to implement number sense strategy. Therefore, it is necessary to develop a learning instrument that consists of the lesson plan, worksheet, and test. This study is qualitative research that only discusses student understanding after implementation of number sense strategy. The participants are 19 students of year 7 in one of the secondary schools in Meurah Mulia, North Aceh, Indonesia. The test used in this study are number sense problems and unstructured interview guidelines. The tests were conducted before and after the lesson. The result of the research shows that the students' understanding of the numbers has increased.
